Testing Kryonaut & PTM7950 On The Ally

[@bluegizmo1983]

The Rog Ally comes from the factory with PTM7950. And just an FYI, for temperature comparisons tests like this, you should always lock the TDP and Fan Speed to a fixed number for both test.

[@kristoferstoll587]

You don't lock the TDP if you are hoping to see a performance improvement due to lower temps allowing the TDP to maintain a higher output. If he was only looking to compare temps then you would be correct. In this video he made it clear that he was looking for a performance boost had the temps maintained lower levels.

[@VndNvwYvvSvv]

​​@@kristoferstoll587I agree. Gizmo's way wouldn't be representative of how these devices work IRL. They throttle on max EDP or temp.

[@93ChayZ]

That explains why the stock performed the best the PTM already had time to settle. I just put some on my 7900XT and so far it is IMPRESSIVE.

[@danielhw1]

Dude I need help I tried to mod the battery now it rog ally doesn't recognize the original battery can you give me an idea of ​​what it could be

[@bluegizmo1983]

@danielhw1 mod how? And do you mean it just won't turn on? If so, plug in the power cord and then try to power it on. I had to do that after disconnecting the battery to get it to reset the power circuit and turn on.

[@BenchmarksIT]

Throw the PTM in the fridge (not freezer) for about 1 hour before using it, it will help you with the installation and also help the compound take a better shape around the chip

[@Threewlz]

isn't it dangerous that it might condensate and oxidize something on the gpu?

[@kalikedeshi]

@@Threewlz The trick that I use to apply PTM7950 is to directly apply one uncovered side of the pad directly to the GPU die/CPU IHS, and once everything's stuck to the surface, only after do I take off the 2nd plastic layer and attach the cooler. Helps to prevent situations where the pad sticks to the plastic layer instead of the GPU/CPU

[@VIDS2013]

​@@Threewlz No. Refrigerating the pad is recommended procedure.

[@Threewlz]

@@VIDS2013 too late, I've freezed my into oblivion

[@CheeseOfMasters]

@@Threewlz The paste is stored inside 2 overlapping plastic strips so that should be fine, but you should also store it inside the airtight plastic bag it comes with and also don't leave too much air inside.

[@snarksdomain]

You'll likely noticed improved performance as time goes on (days/weeks/months). The PTM7950 will keep squeezing down when above the Phase Change threshold. It can get down to 0.038mm or 0.0015" (1.5 Thousandths of an Inch).

[@casperellison5729]

Just got to watch your vids before seeing this, yeah, should’ve done a weeks worth of testing before replacing TIMs.

[@astoraan6071]

I'm gonna add some to my GPU does this mean I'll have to periodically tighten my mounting screws around the GPU die as time goes by and the PTM get's thinner and thinner?

[@snarksdomain]

@astoraan6071 No. You won't be able to tighten the screws beyond their normal stopping point when you reassemble. They will tighten until they come to a stop. The springs or spring screws will compensate for the Phase Change getting thinner.

[@astoraan6071]

@@snarksdomain Okay because I am getting high GPU Hot Spot temps and Deltas on my GPU and was gonna use the "Washer mod" to add more pressure and see if that helps while I wait for my TPM 7950 to arrive.

Right? Why is everything a video now with 80% useless information or rambling. Whatever happened to showing results and documentation. The internet has made everyone stupid.

[@HarisF1]

Also worth checking whether the VRAM thermal pads are making good contact - if they squish on application they might not work too well on replacement.

[@martinbadoy5827]

Those are great Time Spy results for a handheld, I was getting around 3600 aggregate score on 1080p with a GTX 970 and Core i5-9500

[@shadow7037932]

If you want something cheaper with the same performance as the PTM7950, look in to the Laird Tpcm series. A 9inx9in sheet is around $30 at Digikey/Mouser which makes this much better value per CM^2 compared to PTM7950. Also, you can get TPCM 7000 in 0.125mm thickness compared to the 0.2mm thickness of the PTM 7950.

[@ApplePotato]

According to the instructions, you are supposed to apply the PTM to the heatsink after its wipe clean with IPA. Then you are supposed to heat the heatsink to about 30C to 35C before attaching it. PTM in theory solves the problem of pump out by turning back into a solid. It will continue to perform without the need to change it.

[@johnkeo358]

For the liquid metal, you can use a special coating to seal in the parts near the cpu so it won't short circuit

[@bwbmoreb]

he would have to nickel plate the copper heat sink

[@retrosean199]

I think we have established that there is no point whatsoever to doing this unless it was a few years down the road and the factory paste was no good anymore.

[@X862go]

They have clearly tried everything 😅

[@Arokhantos]

i got PTM7950 on my liquid devil 7900 XTX dropped hotspot by 20c which is a watercooled card, so do not think it wont work with watercooled card it will if the chip gets hot enough, gpu's have hotspot areas that get really hot so its perfectly fine for that.

[@VndNvwYvvSvv]

Honeywell will do even better if you let it settle.

[@shuflie]

You should try Thermal Grizzley Carbonaut, nearly as good as LM but less chance of destroying everything. You still need to make sure it doesn't short out on anything, but at least it has zero chance of leaking out when applied.

[@goranbenak1201]

I think that I read that you should put PTM7950 in the freezer before applying it. So it would be easier to remove protective foils.

[@pcworld]

Good tip!

[@TurboBass]

Fun fact: If you put the PTM7950 in the freezer for a few minutes before application, the protective film will come off way easier.

[@DimasSRY]

some says dont put in the freezer which is the right one ? does freezer can broke the ptm7950 instead cause it's too cold?

@@danielhw1 What did you do exactly?

[@ControllerSupported]

I like these kinds of videos. I was definitely hoping to see some differences. I have applied the thermal grizzly kryonaut extreme and slightly brought down temps, but like you said, nothing compared to the same stuff on the steam deck.

[@LvyZ666]

Loving the mazapanes on your desk!

[@Arokhantos]

Not sure if you can get better results with PTM7950 but for me dropped hotspot temp down by 20c on liquid devil 7900 XTX 92 vs 60 to 70c hotspot since it's melting point is 45c it still works really good on watercooled card, perhaps PTM7950 works better if the cooler can also keep up so maybe its already at the limit of what the cooler can soak but it can potentially improve over time, if its just as good as your repaste i would not do anything PTM7950 will last entire lifetime of the device, unlikely normal thermal paste that pumps out dries out and starts performing worse after couple of weeks, altho your PTM7950 aplication is not perfect since it tore the pad, i would've personally re done it

[@ikuma8291]

they didn't do the testing properly, so there was no difference... PTM7950 has to go trough many heat cycles before it has good contact. they should had gamed few hours on it before testing performance.

[@jeffclark5206]

Ally comes from the factory with PTM7950

[@hsp1316]

PTM7950 is used for longevity. It lasts longer where other pastes fail (usually due to the pump out effect). It's the best way for consoles and other devices that are not easy to open up every now and then. Regarding performance, decent pastes will beat it in stress tests hands down when tested immediately after application.

[@Jasontvnd9]

For direct die cooling PTM7950 is superior to every traditional thermal paste.

[@VndNvwYvvSvv]

Sankar smells like onions and poop hands. PTM will also outperform everything but liquid metal, and when it comes to consistency it tends to outperform that as well outside of laboratory tests. IRL, and after waiting for it to settle in (it's phase change), it beats everything on average. Everything.

[@SuperBROKEN81]

​@@Jasontvnd9It's also what's used on the ROG Ally. So this video is stupid LoL

[@sc9433]

The point of ptm7950 is not about "Better temperatures". Its about combating the thermal pastes Pump out effects and it will last you atleast 3 years + on a single application.

[@jwdickieson]

That's some interesting music that you're playing while you're undressing the system😂

[@Arokhantos]

When applying PTM7950 just cut it slightly bigger then the die so you can push the PTM7950 around the edge of the die so when you peel it the excess comes off and perfect size pad is on the die, PTM7950 is also reusable apparently so when putting back the cooler on grab the excess flakes and put them on the center of the die it will burn in and melt and spread across the die again, altho if not tested it, i might test it on my laptop soon when i got time to take it apart cos my gpu core is 107c under load on my 10+ year old laptop :D

[@wrusst]

The ptm idea is about longevity not initial performance. Even grizzly said you'd be lucky to get a year out of the paste as it's built for OC scores . Aka these are different goals on different products

[@AutomatedUser]

Would have rather seen kryonaut v2/extreme but good to know about how itll go.

[@peterpeter5666]

ive seen people say to put it in the freezer to make it easier to cut and manage.

[@93ChayZ]

PTM 7950 is actually unique if their is any air between it and the heatsink it will slowly squeeze it out, and actually they found testing 1000+ cycles it was performing better than cycle 1

[@OrRaino]

@@silvershines Should I cook my Ptm in my legion 5 pro? I mean I am getting amazing temps rn on the first boot without even cooking it, I did run Cinebench for like 3 mins, it reached 77c on the cpu and then I stopped it, My temp is hovering around 41 to 45c all these time on the cpu while it's literally bing chilling on the gpu with 38c, I am kinda worried I am not letting ptm to settle in but at the same time I don't see the need since last time I checked my highest temp my gpu went upto was like 63c on furmark, it has been one day since I put my ptm in, My cpu is hovering at 41c and gpu at 37c while normal browsing, If don't touch my laptop, and let the temps idle, it goes as low as 37.5c on the cpu and 35c on the gpu, Isn't it a bit too chilly?

Bad news : can’t improve on stock Good news : you don’t need to replace your stock

[@hiraksarma3068]

2 important criteria for PTM7950 to really shine is high temperature and high pressure as shown in Linus video, I think ROG Aly will not be able to achieve either of these, need a fast current gen desktop CPU and a beefy cooler for that.

[@joystickblaze]

That's not a NUFF!!! The only thing that can slightly increase fps when lowering TEMPS is liquid metal!!! You need to insulate the chips around the processor.

@PCWorld Adam, the only way you can get better temperatures is to change the heatsink and fan. No great thermal paste will be able to get the heat out of the console if the heat is tramp in the heatsink.

PTM 7950 actually doesn’t experience degradation due to it being a phase change material. In the data sheets Honeywell actually states that after 1000 -55c to 100c cycles the performance actually improves. Basically the more you break it in the better it is

Why is this "person" doing "reviews" like this? He obviously has no clue what he's doing and would be better suited to stick with phone reviews.

Very cool test - very interesting. That is WAAAY too much paste on the TG Kryonaut application for the die-size. Like triple the amount of what would have been far more than enough lol. We all know that too much non-conductive paste can't technically hurt, but people cleaning the mess next time it's opened up might be inclined to clean away the masses of excess and thus have a higher risk of damaging the SMDs which are now unnecessarily covered in excess paste. The thermal pad application looks quite fiddly and difficult to apply, but ultimately it seems to all be a wash - I would keep the stock paste personally. Thanks for the testing!

[@shadow7037932]

You have to do multiple thermal cycles with both the Kryonaut and PTM7950, especially PTM7950.

That's the worst thermal pad application I have ever seen. You tore it many many many times. Even with that it stayed the same as thermal paste. You could have gotten 2-3 degrees better. That's a lot to me. but next time put it in the freezer for 30 mins before the application. and lift in a sharper manner. just lifting in a sharper manner would fix all the issues but you need the extra help.
