RTX3080 Laptop meets Upsiren UX Pro thermal putty and Honeywell PTM7950

[@thomasjohnson8517]

Finally, the video I was looking for! 1. Using the PTM + UX Pro. 2. Initial testing. Decent improvement. 3. 5 week later testing with temps, usage. Dramatically better results. I am officially sold on it now. Thank you for your video. I’m running a i9-12950HX with a mobile 3080 Ti. I hope to get some improvements as I am sitting at 95°C doing absolutely nothing. The LM was applied incorrectly from factory so it’s been throttling like hell. And I don’t care for LM, as I’ve been researching these better hassle free pads. Kind of upsetting for such an expensive machine!

[@fuji748]

Same here, on a predator 300, CPU went from 94°C, 3800MHz, 35W to 79°C, 4200MHz, 45W. Got some improvements on GPU as well ~13°C. It was on thermal grizzly before.

[@TheAwwWtf]

Strix 17 SE? I opened mine up today and the LM was literally everywhere EXCEPT the die exactly as you described 💀 It all pooled up around the cpu and gpu but nowhere on it, I'm waiting for my PTM & U6 Pro to arrive, anything is better than LM atm considering it never stays where it needs to be.

[@thomasjohnson8517]

@@TheAwwWtfYup, G733-CX. It’s annoying. I didn’t know it would look like such a mess. From what I’ve gathered is that if you travel or store your laptop like normal and it tilts, the drip happens. If you can always keep it laying flat, you should be ok. A shame for such an expensive machine.

[@TheAwwWtf]

@@thomasjohnson8517 Exact same model as me, it just took me 3 hours to clean it because of how much liquid metal they put on, like they put a crazy amount on mine, I swear they just ketchup bottle farted out a glob onto the die.. it was ridiculous.. And yeah I figured it had to do with my traveling, the heat issues only kicked in after I had gone on a few work trips where it was lugged around in a backpack and I can only imagine what the turbulence of planes does to it, suddenly went from playing top end games to throttling when I played Half-Life 2...

[@kookymonkey]

How are your temps now comparatively?

[@goorthiss]

Nice to see a PTM test with UX Pro. I tested with U6 Pro and it was also better than on the standard thermal pads from the laptop producer. I suggest for your next tests do a 10 minute throttling test in Cinebench and show the average frequencies of the cores their temperatures and the number of points before and after applying new paste.

Great video man. I ordered some on amazon instead of moddiy as I did not want to wait weeks for delivery. Hope it turns out good

[@snarksdomain]

I'm assuming you're referring to PTM7950? It works really well

[@zqzj]

I've never been a fan of IHS lapping but due to the ultrathin bondline of Honeywell PTM, I could see it being hugely beneficial, especially if the heatsink is lapped on the bottom.

[@K543]

PTM7950 works great on my laptop CPU. It is very hard to find a paste that works as good, I tried many many pastes in the last 3 years. Actually only two pastes were able to match PTM7950 (Koolingmonster Kold-01 and Aerocool Fuzion). Soon I will try the paste version of PTM7950.

[@snarksdomain]

I definitely want to try KOLD-01. Will look into the other one.

[@K543]

@@snarksdomain Maybe it works on your laptop too. I don't understand why so many pastes are so much worse than these two+PTM7950 on my laptop CPU. Maybe Kold-01 and Fuzion are the same, not sure. Some of the specs are identical like thermal Impedance, density, Viscosity. Consistency is very similar to me and performance within +-0.5°C.

That looks really good. Personally I am now using the Kryosheet and its not great but its fine on my Asus advantage edition.

[@Code_String]

This seems like pretty good stuff. I've heard of PTM7950 but never bothered looking into it much. I'm assuming while doing the PTM7950 application, it's recommended to put UX Pro on the chips that need them? I've been looking at Aliexpress to grab both since I've been thinking about replacing the stock stuff Asus put into the two G15 AE's I have.

[@snarksdomain]

I would say most people you ask don't even know what thermal putty is and would recommend pads, but yeah, I'd recommend a quality putty like UX Pro on VRAM, VRM's and anywhere else where there is a pad. If thermal Putty and PTM are good enough for Lenovo to use in gaming laptops, then it should be okay for us too. I'm pretty happy with my laptop results thus far. I will revisit this same laptop a year from now to report on how the thermals are holding up.

[@ultr7712]

Hey snark, I have some questions I'd like to ask regarding Upsiren UX Pro, 1. Will 20g of putty be enough to replace the pads on a PS4 and 3080Ti? 2. How long can the putty last after application? 3. How long can I keep the putty assuming I have excess putty leftover in the container after applying them onto what I want? Thanks in advance btw, keep it up with the tests and vids!

[@snarksdomain]

I would recommend getting 50g. That might even be a bit tight to do both. It should last a very long time, so I would also recommend picking something like PTM7950 for the core. That way you don't have to open it up again for a long time (until thermals tell you otherwise). As far as how long unused putty lasts, it may differ between the putties, but I have ~3 year old TG-PP10 that is still soft and easy to use. I store it inside a zip lock bag at room temperature. My presumption is that most silicone based putties should behave similarly in regards to longevity of storage. As an example, MG860 has a shelf life of 5 years (not very high performing, though). Putties are generally used in long life applications, often never being replaced.

[@ultr7712]

@@snarksdomain thank for the reply! Greatly appreciate it.

[@luisescobedoom2053]

When i come back from my vacation I will try this on my RX 5700 XT for OC purposes, because what really holds back the gpu, Is the hotspots temp Normally if i were to try to overclock my gpu the temp would be this Hotspot: 110c GPU core: 79-85 With those Temps my gpu would normally throttle. So if I used ptm7950 it would help with the Hotspot temp by a lot, Give me thermal headroom for overclocking, And a Rx 5700 xt with good temps will happily overclock. Can't wait to get the full potential out of my silicon chip.

[@KikipasBG]

Hey Snark, thanks for the great video! I was wondering if you have any updated insights on how the Putty holds up over time. Have you noticed any signs of degradation after a year of use? Would love to hear your thoughts!

[@snarksdomain]

I'll see if I can borrow my friends card which has had UX Pro in it for 14 months so far. If so I'll test it again with same parameters as before and see what the temperatures look like.

Hey Snarks, I'd like to repaste my laptop ( ASUS TUF A15, RTX 4050, RYZEN 7 7735HS ). Will this combo do the job? Upsiren PCM-1 and Upsiren UX Pro thermal putty or should I use ARCTIC MX-6 and normal pads?

[@snarksdomain]

@stefonimircea5416 I likely go with Upsiren UTP-8 or Halnziye HY236 if the gaps are really thin. For the core either Honeywell PTM7950, Thermalright Heilos, Upsiren PCM-1, or one of the other similar Phase Change Materials.

[@th3_g0dz_of_Vict0ry]

Great work as usual. Thanks for sharing. I have some unused PTM7950 sheets in my bag and will def be trying them on my Area51m R2 laptop after viewing your interesting results. My laptop has a standard issue 10700K desktop CPU in it though and the gains might not be as signficant when using the PTM7950 on the lapped IHS top surface. The CPU *is* deildded, however and having gotten decent but not great results using LM on the CPU die, I'm wondering if the PTM7950 might be worth experimenting with in place of LM and in between the CPU die and IHS underside.

[@snarksdomain]

It can't hurt to test it out. It's certainly safer to use than LM.

[@th3_g0dz_of_Vict0ry]

@@snarksdomain I've seen some interesting tests (forget the source) comparing LM to PTM7950 and the delta between the two was slim to none after the same repeated heat cycles you demonstrate with your own testing. I believe it was on a typical IHS and in place of thermal paste, though and also on a bare GPU die. Since the A51mR2 laptop is a bit of a special case internally, the typical nitpicky process of getting the LM application *just* right between the CPU die and delidded IHS underbelly is exponentially more tricky. The results were good, especially the freakishly low delta (~1c to 2c) between the 8 CPU cores but the overall thermal gains were not as good as desktop delid projects I've done. Better than the stock Indium "solder" but still not ideal imo. Even though the laptop mb uses a typical and standard 3-point 10th gen ILM bracket with a regular 10700K CPU, the fact that all of that has to be designed within tolerances appropriate to the very dense confines of a mobile chassis make getting that crucial LM-to-IHS equation to resolve is a bit more vexing than say on my 13th gen desktop rig which is also using a delidded CPU; there are just too many design variables (and perhaps compromises) that afffect precise alignments within the laptop chassis and thereby also the end results when buttoning up the CPU delid/relid. As per our other DM on Reddit, I have some Upsiren UX Pro on the way and will be trying that in lieu of the typical TG-PP10 that I've used for a few years now. I opted for the Pro vs the Ultra simply due to your helpful comments on it being a bit more tacky than the drier, clay-like Ultra material. I'll share some info once I have a moment to do the work. Best regards and have fun...

[@snarksdomain]

@s1rrah I believe that was an LTT video where he compared it to LM. That does sound like a tricky laptop application. I've got some Indium thermal pads I need to test out once I do all the shim testing. I bought 2 thicknesses. 1.8mm and 1.6mm (if me.ory serves correct). Will have to see how they perform. Also have Aluminum Nitride shim material.

[@giaanluu1583]

Thanks for the video. The only reason I'm not buying these Upsiren putties right now is because they put the name of computer system gr (the lab that makes K5 pro) on the box. It is kind of sketchy.

I can totally understand that. Hopefully that gets sorted out at some point. If you're still interested in using a high end putty with similar performance and consistency, then I'd recommend Penchem TH949-1.

UTP-8 is cheaper than the other 2. You'll need about 20g of whichever putty you decide to go with. Have you considered using a Phase Change Material on your CPU and GPU core?

Don't know where to get the putty and how to too put the application on it and what kind of brand is good? UpSiren? Cause I cannot find it here in Europe. and I'm going to pair it up with an llano 2024 Laptop Cooler just to get good cool temps overall. Thanks :D

[@snarksdomain]

@Carlos-if4mr Hey Carlos. For PTM7950 you will need at least 1 piece .easuring 40x40mm, but 40x80mm would give you extra in case you run into issue and need to redo it (both CPU and GPU core). As for where to buy PTM7950 you have some options. LTT, Moddiy are both legit and also expensive. You can also buy what is most likely legit stuff from "Passionate Girl Store" on Aliexpress. The Aliexpress stuff seems to have similar/matching results as the Moddiy stuff. There is also PTM7950 on Ebuy7, Amazon, Ebay, Alibaba, Lazada. You'd only want to buy from a seller with very good reviews for that specific product. It might be hit or miss though. You could also go woth something like Upsiren PCM-1, Thermalright Heilos, or similar. Heilos has verification stickers to check if it's real. As for putty, you'll need at least 20 grams. Upsiren UTP-8 is quite good and I think you can find it on Ebuy7 or Alibaba for Europe. You could also go with Fehonda LTP81 or LTP65, Laird T-Putty 607, Honeywell HT10000. CX-H1300 13.5 is good, but recently they've had significant batch variance with it being stuffer. If you get a soft batch it's great, but if you get a stiff batch it is harder to compress during reassembly. Fehonda putties can be bought on Aliexpress or directly from Fehonda website (contact sales and ask for quote). Halnziye HY236 or HY256 are another good option for laptops as it is soft, cheap, and performs decently. Can be bought from Aliexpress, directly from Halnziye website (contact for a quote). Once you have the bottom cover removed, disconnext the battery cable. As for application I recommend rolling logs and placing anywhere there was a thernal pad, then test fit the cooler and tighten cooler screws and press down on the cooler and hold for 20-30 seconds. Then take the cooler back off and see how the putty has spread. Add or remove as needed. Once you think you have the ideal amount then apply the PTM7950 or other PCM of your choice. I recommend cutting it smaller that the CPU and GPU core by 2-3mm on all 4 sides. It makes it easier to do 2nd peel. 80% of it will squish out once you melt it, so all the CPU/GPU will get coverage. I recommend reshaping the putty and then install the cooler, press and hold to squish putty, then reconnect battery cable. I like doing a ~2 hour burn in with Furmark and Prime95/Cinebench (Multi). That way the PCM on the CPU and GPU will both melt and flow out excess. Expect to see initially bad temperatures, with is improving during the burn-in and gradual improvement in the coming days and weeks.

how much of the thermal pad did you use? the dimension? because I'm planning on buying one but I don't want to waste money buying too much

[@snarksdomain]

I didn't weigh the putty before and after, unfortunately. For a laptop, if you only replace the pads on the VRAM, then 20g is enough. Otherwise, I'd recommend getting 50g. It is likely closer to 30-35g by my estimation.

[@TheGal9989]

Appriciate the great detailed video! Would you recommend this putty over the U6 for a laptop?(seems less greasy) combined with the PTM7950 for dies

[@snarksdomain]

I kind of like both putties. Clay like putties are nice to work with, but I can also see use cases where a softer and stickier putty could be more ideal where ocassional flexing/compression are applied to the assembly. Most laptops should be stiff enough to not run into issues, of handled with care. I suppose it comes down to personal preference and budget.

[@nday76]

Hey Snarks, Thank you so much for this video!!! I followed this video to re-do my 2024 Scar 16 4090 laptop with Upsiren UTP-8. I went less than 5mm with a log diameter(probably 3mm). It initially didn't work and I was thermal throttling with 105C GPU hotspot. I assumed GPU VRAMs putty was too thick, normal mounting pressure was not enough to keep the gpu die contact with the heatsink. I generously hand pressed the area where the putty was put near GPU die, and I finally achieved a good temp. I hope others who have a problem with bad temp after redoing thermal putty, they should try to press down the heatsink to squeeze the putty a bit while mounting and screwing the heatsink.

[@snarksdomain]

This is the way. Nicely done :) Yeah, laptops have much less mounting pressure, so it's definitely a good idea to apply some manual pressure to help squeeze the putty. And if anyone runs into issues, a good place to ask for help is the Discord server. It's a growing community and the members have been great at helping each other out.

FYI i have a 2021 ROG Strix G15 G513, should i put something similar to what you have put on yours ?

[@snarksdomain]

That's correct, you don't want to use too much or it can create core contact issues. I like UX Pro, but there are better options for a laptop, and some that perform the same or better than UX Pro and are cheaper. My current go-to is Upsiren UTP-8. It just slightly beats UX Pro, is softer which makes it easier to compress, and cheaper. I also really like Fehonda LTP81 as it is also similar performance and nice and soft (but not runny, just a good soft, easy to form by hand). Fehonda is currently a little more expensive than UX Pro. I'm hoping Fehonda will soon sell it in largewr quantities on Aliexpress. As for the size of the logs I'd recommend taking a look at the Putty Calculator I made on Google Drive (Test Chart Repository). You can also take a look at the latest charts there (VRAM TIM folder > ETCHASH folder) I likely used a little too much and so it took a bit to get the Phase Change fully melted and ideal core contact. It CAN be done with UX Pro, but it takes some care not to use too much.

@@snarksdomainhey! love your content man. would you say that 10g is enough for doing an entire set of thermal pads on a blade 14?

[@snarksdomain]

@sy4nr 10g is never enough. For a laptop you will likely use around 30-40 grams. It's closer to 30 once you get used to using Putty. As an example, on my 3070ti test card I use ~15 grams just for the 8 VRAM modules. You can use the putty calculator to figure out how large of rolls/logs to use. It's located in the Test Chart Repository link in video description. Feel free to "Make A Copy" and modify as needed for your own laptop or videocard. You basically punch in the dimensions of a thermal pad, and it will tell you the amount of putty to match the pad, and diameter to use. The density can effect it, but most good putriws AR in the 3.2 - 3.8 grams per cc.

[@ViperUnleashed]

Can I ask a favour? Is the UX Pro still malleable at Fridge/Freezer temps? Thinking that you could 3D print moulds for the components/strip of components to suit the right shape and thickness. Would help to minimise waste and wouldn't set off the same OCD triggers as the log rolls lol :P

[@snarksdomain]

I hear you on the OCD side of things. I'll try to roll smoother rolls. I'm not sure how malleable it would be at lower temps. May have to experiment. That being said, if you wanted to make moulds you could make them fit around VRAM and then fill them up like Cement forms and then scrape along the top to collect excess. Just be sure to have the "pad" height matching stock thermal pads. With math, we can be very accurate with putty and use the log method.

How many putty did you use in gram?

[@snarksdomain]

@vugiabao7tc425 most laptops can be done with 20g or less. UX Pro is not the putty I'd recommend for a laptop as it is stiffer than others. Laptops have less ability to compress putty so it's better to use softer putties. Better options include: Honeywell HT10000 Laird T-Putty 910 Upsiren UTP-8 Fehonda LTP81 Fehonda LTP65 Laird T-Putty 607 Halnziye HY236 or HY25 For performance comparisons feel free to reference the charts located at the Google Drive link below (Test Chart Repository>VRAM TIM>ETCHASH)

[@snarksdomain]

Upsiren asked me a few months ago if they could include links to my videos in their product listings. I gave them permission to do so, as well as screenshots if they wanted to. That being said, I've seen some charts that look similar and use similar colours as the charts I previously used in my videos (Green text on black backround). Going forward, I'm including a "Snarks Domain" watermark, which they are also okay to have in their product listing if they so choose. I'm not getting any money from this, but it does potentially increase viewers/subscriptions. I do receive some free samples from them, although I have bought more myself than received for free. Originally, when I posted the 3D Graphite video, there was discussion about receiving a portion of profits from sales originating from the link I posted on that video. The sales never amounted to enough to justify actually getting anything though and I'm no longer interested in receiving any form of payment for sales of stuff. To be clear, I made the video of those pads before any discussion regarding any form of compensation, and bought the pads myself.

2:26 that´s how "pump out" effect looks like and Kryonaut is known for this. Arctic MX-5 does the same (but worse, literally all paste will be gone within a month, that´s why they stopped making it). GPUs and laptops simply require different paste, than CPUs. Most of the usual CPU stuff, like Noctua, Arctic MX-4, Thermal Grizzly etc. won´t work there for long. I can only confirm from personal experience, that Arctic MX-6 does work and has no pump out. At least so far.

I just wish I hadn't left it so long. Luckily I mostly game on my Desktop PC. I'll probably get some MX-6 for testing. I've got some Upsiren PCM-1 on the way as well as a piece of Thermal Grizzly Kryosheet, so it will be interesting to see how they all stack up against each other. Will likely test them out on a standalone CPU testbench.

From my experience with Kryonaut and Extreme pastes are not suitable for laptops with high TGP, TDP where the temperature is close to 80°C for a longer period of time.

Hi, thank you for the video. Aorus 15g KC user here (1yr older model slim case). My temps are high and I want to apply PTM7950 to it. The problem is, the difference at thickness will probably make me change my thermal pads too. After seeing your video, I thought "ah.. why don't I use that?". But I have some conserns and questions as ; 1. I know you said the consistency is better but wil I still have to use toothpicks when I want to remove? 2. Why did you use too much? Can I spread it approximately as thermal pads' thickness? 3. Would 10g enough? I also wonder if the PTM7950 is electrically conductive.

[@snarksdomain]

I think you'll be happy with results, although the slim model may have more restricted cooling capability. I'm guessing yours has 115 watt TGP or lower for the videocard? 1. This UX Pro removes MUCH easier than a sticky putty like TG-PP10 or U6 Pro. It will leave a light grey coating that can easily be cleaned up with isopropyl alcohol and a Q-Tip (cotton swab). 2A. I'm using the correct amount as it will squish down easily to the thickness of the gap. 2B. I prefer placing a "rope" of it in place rather than trying to shape it like a thermal pad. It is my opinion that during assembly, the squishing/flowing effect helps to scour both surfaces with flowing putty and does a better job of "prepping" both surfaces and improving adhesion. Another viewer and user of thermal putty (@s1rrah) has a different but equally effective emethid of improving adhesion by rubbing both surfaces with some putty first to apply the light putty film beforehand. I will definitely be trying out their method in the future asit certainly won't hurt and might turn into a "best practice" even. 3. 10g is not enough. You should purchase at least 20g for a laptop. 10g is only 2.875 Cubic centimeters of putty. PTM7950 does not conduct electricity. Lenovo uses PTM7958 on their gaming laptops (along with Jeyi 8100 Putty). PTM7958 is an even higher performing Phase Change Material, and I'll switch to using it as soon as it is available in sheet format. I find the syringe format is difficult to apply and also need extra time and steps to allow the solvent to evaporate before assembly.

[@fatihmtlm]

@@snarksdomain Mine is 105w 3060. I didn't know about the adhesion, I just thought it could be less messy with less unintended spread. I will check the PTM7958 and consider the putty since you conviced me. Lastly, did you use max fan in the benchmarks? Thank you very much.

[@snarksdomain]

@AmanSingh-xk1me 30g of UTP-8? You must have order a 20g and 10g container I'm guessing? 20g will likely be enough. Before you go to apply the PTM7950 I recommend applying the outty and then doing a test fit woth your heatsink and start the screws in partially. The press down on the heatsinknwoth younhanda and hold for maybe 20 seconds. Then tighten the screws until they come to their natural stopping point (don't use excessive force). The. Remove screws and cooler and inspect how the outty has spread, and remove excess. Once you are happy with the amount of putty then you can go ahead and apply the PTM7950. I recommend cutting it smaller than the die size by ~3mm (1/8") on all 4 sides. It will make application easier, and 2nd peel easier too. Peel one side, place on die (don't worry if you don't get it perfectly centered). Run finger over it (with top plastic film still in place), and then use tape/stick at a corner and slowly peel towards the opposite corner. Stop if it starts to tear. On finally reassembly you will want to reshape or at least pinch the putty a bit to make it "stand up" a little. You want the putty to get it'a final compression during assembly. Don't flatten it like a pad. I prefer rolling it into logs myself. If you run into any issues or want share pictures and ask for feedback while doing it the you might want to join the Discord (link below). *Edit: I used too much putty in this video. I made it work, but had to apply more pressure than ideal to get it to compress properly (partly because UX pro is a bit stiff for laptop applications).

It's possible it could be throttling for some reason, but hard to know for sure without testing a few things out. I'd recommend installing HWINFO64 and running "sensors Only" and then recording a log (bottom right). Then make sure your laptop profile is set to a performance mode and playing a game or even running a stress test with Furmark to see what the wattage is. Then you can go back a look at the log, voltages, temperatures, and have more data to go off of to try figuring out what the main issue is. If the VRAM or VRM's are not getting adequate cooling then it could definitely effect performance. If that were the case, then either new pads or Thermal Putty would likely help. I'd personally opt for putty over pads, but that's my personal preference.

This is true for 30 series laptops. HWINFO64 can show/log other stuff though like "Reliability Voltage" if it was running unstable. You should also be able to Conditional Format the voltage numbers for each voltage value and see if voltage changes after a while of the laptop warming up.

Check the charts in the video description (Test Chart Repository)

[@RGRG-vc6ii]

I have UX and I'll give it a try. PTM 0.2mm on CPU and GPU, not too much UX on the vram so that ptm hopefully makes contact. Thanks!

[@RGRG-vc6ii]

Oh... One more thing. If PTM 0.2mm will not make proper contact, is it possibile to stack 2 layers of it? When it melts, the 2 layers should fuse, isnt It? 😂 Higly experimental

[@snarksdomain]

@RGRG-vc6ii You should be fine with just the one layer. Having 2 layers would not be ideal as your CPU and GPU core temps would be horrible with a gap that large. Of you run into core contact issues it would be best to apply some pressure to the cooler to help squish the putty and try again.

[@RGRG-vc6ii]

Hey it's me again. Had to service another laptop and got mad messing up with gelid pads thicknesses. Now it is ux time on my Msi GS75. I beg you for one last tip please: From factory it had 0.5, 1 and 2mm very very soft thermal pads plus a thin layer of a paste similar to k5 in a small socket. What diameter for the ux rolled logs do you suggest to apply? I'm trying to pinpoint a single diameter for everywhere to simplify the whole thing... Thanks!

I can verify that not peeling the film leads to bad thermal results.. facepalm

This tells me my 140w rdna2 shiddy MSI mech has plenty of thermal headroom with this pad. It has the Same heatpipe design and tdp as that 3080 laptop but with an extra fan for chuckles sake since its a dgpu.

[@snarksdomain]

It's quite possible you could see some improvement, but obviously I can't guarantee anything. Lots of variables at play. I will say that the faster we can transfer heat to the cooler, the hotter the fins get, which increases the delta between fin temperature and air temperature. The higher the delta, the more joules of heat that get dumped into the air passing by, and the higher the cooling affect. For some it will result in lower temperatures (fixed or max fan speed), for others it will mean lower fan speed and a quieter PC. Depends which matters more to you.

[@TheDocatron]

Awesome videos, you're extremely informative! I purchased a Asus Zephyrus Duo 16 (2023) about 5 months ago and recently started getting signs of thermal throttling. My GPU memory junction is reading 102c and gpu Hotspot will hit over 87c (seen it as high as 91c). CPU temps on this thing run hot too, over 95c in games unless I turn boost off and it'll stabilize around 73c (also in games). I repasted the gpu with thermal grizzly paste, and the cpu I redid with thermal grizzly liquid metal. However, still getting these ridiculous temps, so I'm thinking I missed a spot somewhere or didn't get a great application. Finally got my ptm7950 sheets in, and I have Upsiren UX Pro coming today too. Hoping to see some great results with this. Questions I have though, is how much putty should I roll up for that laptop? Im sure you don't have the same brand laying around, but what size diameter log should I shoot for? And how to know I'm not adding too much that it's causing stress on the Vrms? Again, solid stuff, your vids are such a great resource!

[@snarksdomain]

That's a nice laptop. Cool that it has memory junction sensors. For putty log diameters you can calculate it based off OEM pad thickness x OEM pad width (or width of component). Examples: (numbers in brackets = log diameter) A) 2mm x 8mm pad = 16mm^2 --> (4.5mm x 4.5mm) x 0.7854 = 15.9mm^2 B) 2mm x 15mm pad = 30mm^2 --> (6mm x 6mm) x 0.7854 = 28.3mm^2 C) 3mm x 6mm pad = 18mm^2 --> (5mm x 5mm) x 0.7854 = 19.6mm^2 D) 3mm x 15mm pad = 45mm^2 --> (7.5mm x 7.5mm) x 0.7854 = 44.2mm^2

[@TheDocatron]

Update: I cleaned up the laptop pretty thoroughly last night, replacing the liquid metal on my cpu with PTM7950 and use ptm7950 on gpu. Upsiren UX Pro went on my VRMs and VRAM components, I rolled logs about 4-5mm thick. Air duster on fans and all that fun stuff. I fired up a quick game (didn't have much time to do benchmarks for a burn in on ptm7950 before bed), played for about 30mins. Usually during this time before replacement I'd get thermal throttling within 10mins and then practically every 1 min intervals. No thermal throttling in that 30mins after replacement. Temps did seem to get slightly lower as time went on, and I expect they'll only get better. Memory Junction temps went from 102-104c max down to 96c max, which I can live with. Gpu temps with 100% usage in the game was hitting a max of around 79c, Hotspot hovered around 85c with a max at 89 only once at the beginning. CPU just runs hot on this thing, with it sitting at 99c at the beginning then went down towards 85-88c towards the end of that session. So far, I'm satisfied with these results, as again I expect as the ptm7950 gets settled my temps will only get better. Awesome stuff between the ptm7950 and UX Pro. Also, I'm a little avert to liquid metal now after seeing what it did the the plate of my heatsink after only 5 months, I can't see that stuff being great for your heatsink long term.

I've also locked the CPU at 4300MHz at 1.225 volts and plan to use those as the parameters. I'll need to redo the MX-4 test, but so far PCM-1 looks like it has decent performance, even after only an hour of running. I had been testing with an AMD Wraith Prism cooler, but have now switched to using a Noctua NH-U12S. This will allow me to test liquid metal and be able to compare the results (nickel plated) I can confirm that PCM-1 is definitely a phase change material. Moddiy purchases have been smooth.

Hi. Maybe someday you can test laird products. That´s what i use, so i´m curious. But gives me good results. I use laird tpcm 7400 phase change material for bare dies. (7400 is 0.4mm thick, 7250 is 0.250 and 7100 is 0.1mm). I use tputty 502 (bulk, not the sheets, that have fiberglass) for vram and vrms. You also have tputty 508, 607 and the new 910. I never tested those. I like tputty 502 because doesn´t have silicone bleed and when it´s reusable. I just grab it, make some small balls, compress it to 1 or 2 mm more that the gap to fill and it´s done. I´ve not seen any thermal degradation on my 3080 after 1 year of continuous use, but i´ve applied again(the same putty that was used) when i replaced carbonaut for the tpcm 7400(for testing purposes). The same temperatures were observed. You can find those products on mouser. Thanks

I'm considering testing the PTM7950 material in lieu of LM on a delidded 10700K in an A51mR2 laptop and may throw the 7400 in with the rest of the testing. I'm curious what the slightly more consistent (possibly more stable) thickness of one of the phase change sheets might make in mitigating the common difficulties one will see in getting the highly liquid LM contact just right between the CPU die and underside of the IHS. It would also be nice if it's effective as the need to apply LM to both the CPU die and IHS would also make things easier overall. Thanks for that referral. I have not looked at the 7400 option but will be reading up on it shortly...

[@chicozeb]

@@th3_g0dz_of_Vict0ry i used on an rtx 3080 desktop and gives me 10 to 11°C difference between the die and hot spot. That difference rises to 12 to 13°C with carbonaut, but die temp only rises 2 °C. With hydronaut the hotspot difference is 11°C after application, 15°C after 6 months of light usage and rises to unusable levels after 1 year(105°C total hotspot temp). I've also used on my legion 5 pro. That laptop does not make good contact on the gpu. I have to use thick phase change material. I have no experience with lm. I only touched it on the ps5 because it's ready for lm. If you use a thick phase change material like the 7400, it will cover all the spots that may not be making good contact. It will flow rapidly and compress to the right thickness after 2 or 3 minutes of reaching something like 70°C. Maybe you will get better temps if you dont use the ihs, but you risk damaging the die that way. If you use the ihs, maybe dont glue it, because if you do and the glue dries, if can prevent the phase change to compress to the optimal height. If you put the glue and can heat the processor before the glue dries, it may not have that issue.

It has vram heat problem due to poor stock thermal pad contact. With the u6 pro, temps goes from 108C to 75-80C avg. Unfortunately the gpu temp goes higher than stock. Could it be the better vram heat absorption affecting the gpu temp? Before it only reach 70C or so but now it can hit 87C throttling it at same fan speed. Reapplied 2x times.

It could be too much putty if your CPU temp is that high on the second laptop. Lenovo uses PTM7958 on laptops which is said to achieve temperatures that are a few degrees cooler than PTM7950. It could also be that it just needs a burn in. I'd maybe expect a couple degrees warmer with the improved cooling of VRAM, and maybe a couple degrees changing from the PTM7858, but not in the 80's.

As long as your temperature isn't going over 90 you won't be hurting anything. After it gets it first melt, little air bubbles will work their way out as the now fluid Phase Change Material very slowly flows out like a normal paste would. This allows it to gradually make the layer of material thinner. A higher mounting pressure would achieve good results faster, but I wouldn't recommend playing around with mounting pressure unless you are co fident in doing so and understand any potential risks. From my experience the thermal.al performance gets better quite a bit in the first couple hours of stress testing/full load, and even further slight inproveme t over the next few weeks of normal use.

Hello. I consulted one laptop service center guy, he said that after applying laird instead of stock thermal pads, in order to not risk to crack the chips(because of increased pressure), he uses some custom silicone washers. Can you comment on this? Thanks.

[@snarksdomain]

I've heard a few people mention the possibility of increased pressure on the core before. I haven't used any silicone washers myself, but it likely wouldn't hurt if you were concerned. Lenovo uses thermal putty in their laptops. Perhaps they've designed the mounting pressure with this in mind. For my laptop, it didn't seem like there was a lot of spring action by tightening the screws. In my mind, a GPU with a stiff springy "X" mounting bracket, it would have potentially higher risk of such. Either way, if using those silicone washers doesn't affect core contact, then it can't hurt. The PS5 similarly uses thermal putty. I think a lot of people don't like the idea of a putty simply because it is different than what we are used to. Putty lends itself well to automated application, whereas pads need someone to put them in place. In general, I think we'll start seeing higher quality pads and putties used going forward. With GDDR7 coming soon the power density will likely be higher and so we will need high performance thermal solutions to deal with the added heat. We'll start seeing more GPU's with vapors chambers and laptops as well.

@@snarksdomain Great reply, thanks a lot, will think what to do. The washers are tricky, because I don't know which ones to use, will probably have to order them from the same service center, where I order ptm (which they claim is the original one).
