How LOW Can It Go? | Steam Deck Thermal Modding

[@cryobyte33]

As a note about the vented backplate: 1. I tested VRMs, ICs, the SSD and the RAM for temperatures with the vented backplate and saw less than 1 degree difference from the stock backplate. 2. A lot of air still gets taken in through the rear vent, even with the vented backplate, so I have very few concerns with device longevity, but wanted to be fully transparent! Edit: I used the "sensors" command for SSD and motherboard temperatures, spot checked with the other results I gathered from MangoHUD. The ICs and VRMs were a bit more difficult. I used a temperature probe wired through the back vent to measure the surface temperatures, and verified its accuracy with a backplate-off IR thermometer test. Obviously the backplate-off results are cooler, but I verified that the probe was accurate that way.

[@bits2646]

OK that's the answer I was looking for :)

[@Meninem_]

Finally bro, thank you for relieving my stress with the vented back plate. I bought it but started to think about how tf air passively cools the Ics, ram, etc

[@lanydaen2702]

I love this video, but I wish you went into as much detail about your validation of all critical component temperatures as you did with the rest of the testing methodology. The airflow the way Valve designed it is very much needed to keep things like the charging IC and MEM4 within safe temperatures, as per GN's analysis. While I am definitely open to the idea that the JSAUX backplate could be an improvement all around and would love the performance/aucoustic gains, I would need some more details than (crudely put, I am sorry) "trust me, I did some testing and it all seemed fine to me" in a comment. It seems like you actually did some thermocouple testing, I would have love it if that was included in the video! I'd love to modify my Deck in this way, but as it stands the details as to the thermal safety of doing so just aren't enough for me to risk my Deck.

[@Frencho9]

👍 Thanks!

[@GogOlo4]

Your videos are really cool! But what about the power consumption? If the SoC has more headroom in terms of temperature and therefore keeps the clock more stable, it should also consume a little more power, right? Or is that compensated by the lower power consumption of the slower rotating fan?

[@jackinabackpack7599]

Kyle. You are the gift that just keeps on giving! There is a lot of scattered content on thermal modding but the video you created has the next level of polish to it. Sincere thank you from the community.

[@warpathh]

It would be awesome if you did a Steam Deck OLED thermal mod including re-introducing thermal pads, thermal plate mod (to accommodate the pads contact), and PTM9750 APU instead of thermal paste, and the JSAUX back!

[@cryobyte33]

I haven't heard of the thermal plate mod, could you send an email with a link to the address on my about page? Thank you!

[@warpathh]

@@cryobyte33 the new thermal plate on the OLED unit has an insulating layer, and cut-outs in it for where the thermal pads from the heat pipe touch the metal plate. You’d have to cut the black insulation plastic layer wherever a thermal pad touches. The new OLED model doesn’t have thermal pads on most components now… It’s a cost cutting measure. You’ll see it if you look at the Gamer Nexus teardown to see what I mean.

[@TheDarKris]

I have the OG JSAUX Backplate and I also did a repaste but after watching this video I bought the thermal pad as well as the new jsaux backplate. My temps on my OC Deck have been basically always in the 80s so seeing those temps drop will be greatly appreciated

[@jompkins]

Thanks for the video! Some dB(A) info for you: - This measurement is on a logarithmic scale - Every 10 dBA is equivalent to a doubling of sound pressure. - Example: 2.7dBA is NOT 2.7x louder - that's closer to 30% louder IF measuring the exact same tone. - Example: an 80 dBA sound is 4X "louder" than a 60dBA one. This is the difference between a normal conversation face to face and a movie theater. - dBA is a measure of sound pressure - not necessarily perceived volume, and: - Higher frequencies will generally sound much louder to us than lower ones at the exact same dBA measurement.

[@cryobyte33]

I knew about the logarithmic scale and the frequency thing, but not the rest, thank you so much for explaining! I'll screenshot your comment and be sure to follow up with more research where needed, I appreciate it! ❤️

[@bruhwhirl]

Would you consider making a follow up video on this when used in the long run? As you stated, there *could* be issues with removed airflow to other components, but it's probably impossible to tell in such a short amount of time. Would be interesting to see how or if it changes with time.

[@cryobyte33]

I might be able to later, but I might be doing other mods in the meantime so it'd be hard to isolate changes. What I can tell you, though, is that: 1. I tested VRMs, ICs, the SSD and the RAM for temperatures with the vented backplate and saw less than 1 degree difference from the stock backplate 2. A lot of air still gets taken in through the rear vent, even with the vented backplate. Hopefully this alleviates some of your concerns, thank you for watching!

[@Frencho9]

Jsaux new backplate with thermal pad and fan intake vent looks promising especially if you want a quieter Steam Deck, but I'm worried it cools down the APU better but removes airflow to other critical components like SSD, ddr ram memory dies, voltage regulators, battery and other components that might get too hot now and fail earlier!

[@cryobyte33]

I mention that concern near the end of the video, but also mention that I watched all those temperatures and that they stayed identical and have given me no reason to worry about them 🙂 Thank you for watching, I'm glad it helped you out!

[@brcosmin]

wondering if covering the circular fan intake with duct tape does anything to performance and temps of the SOC.@@cryobyte33

[@jinx20001]

when you think about it... its much like a normal desktop pc right... the only components that typically get direct contact cooling with fan assistance or water cooling are the gpu and cpu with some motherboards getting a fan on the chipset but its often not required. everything else will have a smaller heat sink that is cooled passively, as long as that original opening is not blocked then even with the fan being open to get its air supply it should still drag air in from the original opening, i just dont see it being an issue, all components should get adequately passively cooled.

[@mickw1523]

I recently fitted the 'old' jsaux back plate. I removed the thermal pad prior to installing the shell.. I wasn't after a shell to cool the deck down, more for the looks, since I opted for a transparent purple back plate. I don't notice any difference in temps... but now I feel that I maybe shouldn't of removed the thermal pad.. The reason I removed it, because I heard that the pad actually blocks the air from passing from the vent at the back to the fan.

[@dinglebop9998]

Audio engineer here. With the acoustic measurements in the A weighting (which refers to how the volume of sound reacts to what we here, as we hear different frequencies at different perceived volumes), a 3dB difference is twice the acoustic energy - audio is measured on a logarithmic scale so it would be perceived as a small increase in sound, but the "2.7dB increase," for example, is not 2.7 times louder. It is less than twice as loud, but would be perceived as a small increase in volume.

Kyle, another great video. I'd like to share my setup, experience and also ask a couple questions. First, I am running your CryoUtilties and followed your excellent Undervolt & Overclock video. My best stable setup was UV = 40/30/40: OC = CPU 3950 / GPU 1800 : TDP = 17 Watts. After replacing my back plate with the newest JSAUX, my current stable setup is UV = 40/20/40: OC = CPU 4300 / GPU 2100: TDP = 20 Watts. The back plate made a monster difference in deck temps. Second, I've used a few different tools for benchmarking & stress testing (cpu-x, Superposition, gtkstresstesting (locks up on me) & mprime) however, I've never seen my CPU run @ more than 4058 or my GPU @ over 2000. So, it doesn't seem to matter if I tweak the BIOS settings above 4000 & 2000 respectively. My next step is to crank up TDP to see if it makes a difference. Any thoughts on a better tools for benchmarking or what I may be doing wrong? Temps at my current config are low 70's to low 80's while pushing the deck hard, seems there's room for more juice.

[@spookysack]

This is a great video, but I had to pause on your charts quite often to read them. One thing that would aid their digestion is to color code. Since you often had 2 or 3 direct comparisons shown on the same chart, you could use related colors to distinguish the tiers. For example, you could use two shades of red for the overclocked comparison and two shades of blue for the non-over clocked comparison. Hope this helps and keep up the highly informative videos!

I actually did test the VRMs, SSD, RAM and ICs (and mention it in the concerns section), they were within 1 degree of stock and gave me no reason to worry whatsoever 🙂 The fan still pulls air through the back vent and the metal plate also contacts the heatsink (which is getting better cooling). Thanks for watching, I hope this helps!

[@RetroWaveArcades]

@@cryobyte33 apricides for video but I must ask - how you measured temps of IC, SSD, VRMs and battery? I heard yours concerns but I have mine as well kzbin.info/www/bejne/hJa0eZKVjbuUbJY With this hole above fan I treat this backplate like there is no backplate at all because negative airflow is interrupted. I wonder what temps of battery are at your tests while gaming with docked deck.

[@cryobyte33]

@@RetroWaveArcades While negative airflow is interrupted, it still pulls a ton of air through the back plate. The fan can pull quite a bit more air than normally gets to it. As for the temperatures, I used the "sensors" command for SSD and motherboard temperatures, spot checked with the other results I gathered from MangoHUD, and checked. The ICs and VRMs were a bit more difficult. I used a thermocouple temperature sensor wired through the back vent to measure the surface temperatures, and verified its accuracy with a backplate-off IR thermometer test. GN does really good work, and I want to make it clear that I'm not trying to argue with Steve's results. All I know is that I did the best I could to to verify that this would be safe for long-term use. 🙂

I was thinking about getting the PTM7950 and new JSAUX backplate, but was concerned what the actual games were. This video definitely helps make my decision easier. I might just get the backplate and use some thermal paste I already have. Don’t want to setup the PTM7950 if it is all going to come out for a p3r. FYI I saw Salocin900 posted a video of an updated Steam Deck which has different mounting screw locations for the heat pipe. Might be an issue for the p3r if Valve has significantly changed the design.

[@johnboy2436]

whats a p3r? Would like to know what you mean as im thinking of ordering the thermal pads but have some mx6 paste here? Cheers

[@kris2501100]

Thanks for the insights. I’d like to add 2 cents to it. The stock backplate isn’t that great in terms of thermal design. Warmer air has higher static pressure. Stock plate has intake vent right above the silicon cover, which is heating up the air and causing elevated pressure that will hinder cool air from flowing into the chasis. That’s why fan speed has to go much higher to counter that effect to keep air flowing into the chasis. I think the best backplate will be a vented cover with metal plate exposed for magnet peltier cooler.

[@DeadExplorer]

Fantastic video! Definitely gonna get the vented backplate when I get a steam deck.

[@CosmicApe]

While dropping ~5C is definitely awesome. This just goes to show you how well designed the Steam Deck is from the get go. Valve really has some amazing engineers on this product.

[@HekaWaset]

Thank you for this video. I have been on a cooling odyssee ever since i bought the deck myself. I tried out all the methods you demostrate in this vid, its really good to have you coming up with pretty much the same results. Cheers mate, keep up the awesomeness. Edit: With that being said, the weirdest thing: I spent half my time in a desert country, andwhen I'm there the old JSAUX backplate combined with a magnetic fan is what worked out best for me. Not so when I am back in western europe though. Also, there are concerns with JSAUX new backplate in regards to internal airflow and cooling of other elements, specifically the SSD. I even think to remember that Valve had once mentioned waz back that this was the reason for the absence of a second vent in the stock configuration.

[@cryobyte33]

Thanks for watching and for sharing your results! The locational difference is almost certainly humidity, with drier air you'd need more fan/watt to keep temperatures down. As for the new backplate: 1. I tested VRMs, ICs, the SSD and the RAM for temperatures with the vented backplate and saw less than 1 degree difference from the stock backplate. 2. A lot of air still gets taken in through the rear vent, even with the vented backplate, so I have very few concerns with device longevity. Hopefully this helps 😁

[@chamamemestre]

This is so cool, thank you for having the JSAUX. I have both, although I noticed that JSAUX might have taken into account one of my emails to them, because the RGB backplate (still hasn't arrived, so I can't say for sure), looks like, according to the images on their website, to have a section cut-out on the thermal pad to allow for the original Valve fluid dynamics diagram. If true, it will help a lot. I have also got a cheap (from Amazon) aluminium heatsink (40x40x11) with thermal adhesive to directly put over the aluminium backplate. This setup is perfect to use with the JSAUX also new RGB hub. I know it sounds like an ad lol, but I am just really excited for it to arrive (September according to their website).

[@cryobyte33]

Thank you for watching! I love JSAUX products thus far and don't have many complaints. I don't have an RGB plate, but hope to get one after I'm in the US to test.

[@DominicMalta]

Seeing you’re video hit my sub box always puts the biggest smile on my face because i know how much hard work and time it takes testing things like this take, And someone with OCD&HDHD I really appreciate the effort you put into your testing with all the different independent variables there is when it comes to testing the smallest of things. I’m planning on water cooling my steam deck in an upcoming video if you ever have the free time I have some questions about attending to dd this stupid idea of mine

[@cryobyte33]

Thank you so much for watching the videos and being subscribed! I'm happy that you enjoy them as much as you do, and that it can hold your attention since both my wife and I have ADHD. As for water cooling, feel free to either email me at my business email, or join the Discord server and start a thread to chat through it 😁

[@CapsuleCorpDude]

Need that clip on fan. Honestly I had one of those jet airplane ps4s so I’m sure the noise won’t be anything crazy lol.

[@f.ferenc88]

Thank you very much for taking time doing all this work!

[@paolo705]

Today I've tested the undervolt settings on the 118 bios, I'm on -30 cpu, -40 gpu, -50 soc, any higher I would start to see corruption/random shut downs. I stress tested with Doom eternal (raytracing, low resolution, low settings), with a 4k video running on the background (gpu at 99%, cpu at 95% average), and also with mprime (for ram, altough I used "blend" option). My termals were pretty good already, as I'm rocking the old jsaux plate and that does already some good job at lowering the temps, but noticed the new backplate that you showcase in the video.I decided to make a hole in the superior part, where the top of the fan would be, the hole is about 70 x 200 mm, and my temperatures have gone down by 2-3 ºC compared to the unmodified old backplate, fan speed lowered about 600 rpm. The way I cut the backplate is by warming up a cutter and a lot of pacience, it definitely doesn't look clean but pretty functional, thanks for your videos.

[@SeesSean]

Your dedication to your test earned my sub! i hope you keep it up brother man.

[@detroitfinedining]

This is exactly the video I was looking for! Thank you!

[@peanutbutter625]

I don't even have a steam deck (still thinking whether to get one) but this is fantastic. You're like the Steve (from gamers nexus) of steam deck.

[@PopCultureGamers]

In terms of the clip on fan from Jsaux which is only compatible with the stock backplat, I purchased two different versions of this, there is a kickstand built into the foot of the clip on fan which allows you to stand it. Also, there is a version which does not require the clip from Jsaux and is sold seperately as part of the ModCase, but it includes a metal stick on connector that also gives you the latch from the ModCase which lets you add other ModCase components (but not at the same time). I also tried PTM7950 and that was a total bust, in fact in some cases it made my Steam Deck hotter and definately made the standard case back a lot warmer. Maybe it depends on what model of Steam Deck you are testing on and if Valve used different paste in construction.

[@blade8424]

Didn't know you could replace the fans and thermal paste. Good to know. :) Saving video for future reference. Ty. :)

[@rafaelr5754]

JSAUX back plate is no Joke, my wife's steam deck used to thermal throttle and just froze the games FULLY if the game was demanding. I used the JSAUX back plate, the one without the vent and changed the Thermal paste, added a thermal pad to the aluminum cover inside and BOOM, the temps were SOOO MUCH cooler. This is a must mod for the STEAM deck.

[@cryobyte33]

I didn't have the same issue with stock, but I agree that the JSAUX backplates are both big wins for thermals 😁 Thank you for watching and sharing your experience!

[@carmenandcasey]

Didn’t skip a single second. Definitely subscribing after this!

[@klausschwab11]

I bought the magnetic fan a while back and no one had any tests on it. I did notice it worked but it is cumbersome in some regards. I ended up modding my JSAUX old backplate by cutting holes where the fan is like the new backplate they offer. Then I added heatsinks on top of the metal plate. It has cooled down the Steam Deck alot. I did my own testing with before and after results and it does work. My deck is overclocked as well. My settings are undervolt 30-10-30. Overclock 4077 CPU, 2077 GPU and 20777 for the battery.

[@cryobyte33]

Sounds like that was a great idea, I was thinking about cutting a hole in my metal plate backplate too! I'm also glad that my testing aligns with yours 🙂 Thanks for watching!

[@klausschwab11]

@@cryobyte33 Yeah I ended up buying two of those backplates before they announced the New one so I had a spare to experiement with. I cut down a mesh fan screen and a used non scented dryer sheet to protext the fan from dust build up on the fan. I wonder if that maybe helps with back pressure as well? I also added a few thermal pads inside the deck in a few spots to help disapate the heat. I will have to try that thermal pad you mentioned in your video. I keep my house around 25c degrees and luckily I am able to keep the deck pretty cool. It is all thanks to you that I was able to learn how to unlock the potential of the Steam Deck through undervolting and overclocking. I look forward to any other videos you do.

[@inudesu5572]

I live in the desert. (AZ) It's usually no cooler than 80°F in my home. Currently have the old metal plate Jsaux that is effing HOT! I used these links to get the new back and the Honeywell pad. Liked, subscribed, and will look into your patreon.

[@Frehgin]

Thank you so much for this video, I will be looking into the ptm7950 thermal pads, sticking with the stock back plate believing in the air flow pattern valve went with.

[@cryobyte33]

Thanks for watching, nothing wrong with that! The negative pressure flow that Valve went with is definitely great and well-researched, but falls over a little bit when pushing more than 15w into the APU. Regardless, it's great that we have the option to use whichever we want 😁
