GPU Overheating after new paste and pads

@@northwestrepairi have a problem with my 3090 ti too, at like 250-300w powerdraw its already at 70° degrees, hotspot at 100°+, 30° delta, you think its just the paste or could it be more? best regards

Your videos are so therapeutic 😊👍

[@northwestrepair]

thank you. i try.

[@kulilin3104]

The 4090 FE cards use Honeywell PTM7950 on the core. It phase changes above 50°C. Looks like the owner left that on the core and only changed the pads to the wrong size. Due to PTM7950's phase changing nature, it looks dry like that until it heats up. It's designed for extended life while still being highly efficient with thermal transfer. I've used it in laptop paste replacements. It's pretty awesome from my tests.

[@Jasontvnd9]

I used honeywell on my reference 7900XT after the paste kept getting pumped out after 3-4 weeks. It's really good stuff it now runs 60c gpu and 73c hotspot. Before with TFX paste even after I had repasted I got 63c core and 84c hotspot which was actually OK until a few weeks went by and the hotspot was close to 100c again. I've had it with ptm 7950 for 2 months now and it's actually improved slightly, was a 16c delta between gpu and hotspot and now its pretty much always 13c. I'm very happy with it.

[@kulilin3104]

@Jasontvnd9 I finally got around to using PTM7950 on my 7900xtx after my hotspot temps crept up to 85°C. After three extended burn-ins, it's now maxed out at 70°C at full load. This stuff gets better and better the more burn-ins you do it seems.

[@harrydijkstra9936]

I fully switched to PTM for laptops and vga cards with natural high temperatures and turboboosts, paste, especially low viscosity (high silicone filler content) degrades/pumps out fast with temperatures of 80'c and higher. Also depends on contact pressure and uniformity/flatness of both surfaces, it lasts longer on perfect surfaces. Pumpout resistance is specified on the "real" manufacturers datasheets: DOW, Shin-Etsu, Laird, 3M etc, a lot of known consumer brands don't make their own paste, example Thermalright TF3 is most likely rebranded Shin-Etsu X23-7921-5.

I was hoping you'd use the pad roller to squish the pads out. Thanks for the video!

[@dano5238]

You are an old world craftsmen. Great video.

[@UrokLizard]

As far as your furmark stress test goes, there is a very big difference with how furmark stresses the memory subsystem of rtx 4000 series. I believe most of the data fits in the large cache which is why memory temperatures appear to be very good. You may need to experiment with other 3D apps to get higher memory temperatures

[@northwestrepair]

Yes but for diagnosing a problem, it's enough. I don't need to complicate it anymore than it already is.

[@tourmaline07]

Also I know that modern nVidia drivers massively downclock the card with Furmark running to protect the card , I used Port Royal Stress Test to check stability of my 2080ti when I overclocked it. But Furmark is still good enough to reveal issues with broken cards (not overclocked ones though).

[@taiiat0]

it's fine, the vRAM on Lovelace Cards runs pretty comfortable. guess they got enough flak for high end Ampere Cards being a miniature disaster.

[@GoonyMclinux]

He found the issue correctly and fixed it, no further work was needed.

[@Helifax19]

yes, Furkmark (which is heavily bottlenecked since at least 10 years and the GTX 480 dramas) are not a true representation of a real time scenario. Port Royal or Speed Run are better representations. However, you can still use it to load parts of the card and immediately see if there is an issue or not.

It might be just me but I always enjoy watching a reflow.

[@andrey.003]

also planned to replace pads and paste. this video will serve as the right guide to it. i didnt even realize that the pads could make such problems to GPU if the thinckness is wrong.

[@EliteRock]

So many people just don't get how important it is to get pad thicknesses right on graphics cards, and how difficult it can be. You can get away with thicker pads (a mm or more over) for some of the (very) small components scattered around the board, but for any chip more than a few mm on any side they need to be precise, as in c. 0.1-0.2 mm thicker than the gap they bridge (depends on the type of pad - squishy, mineral-based ones give you more latitude, crappy silicone-based ones practically zero).

[@TTTorpedOOO]

man, you are dedicated, no joke. 👍

[@stuartX11]

I bought some of the black and red screwdrivers you use. They’re very good but I learnt that if alcohol is spilled on them the size markings drip off with the solvent.

[@fadedninna]

i love your vids sir, keep doing them please

[@gennavandella]

I used thermal paste instead I got 83 degrees. I dug around and found out it wasn't the right amount and spacing. So I spread a tin layer on gpu processor and right chips. And then applied thermal paste in the middle, mid drops of it. I then put the cover and applied less pressure on the screws. I found out once the screws are lock when tightening stop, and got 78 degrees on max stress and 40 on no stress. Note I only have one gpu fan working at the moment. There has to be a tiny gap between the cooling plate and cpu/chips etc. That gap must have a tiny bit of thermal paste in it. If the screws are too tight it would have almost no paste on the components. So just apply the right amount of pressure. Also thermal pads get squished when pressure is applied, so reusing old ones means more pressure to have contact. Once you set new ones down close it, then open it back. You beak that connection. The connection has to be tight that's why thermal pads stick. Another thing I found out is all case fans has to be pushing air out, none should pull in air. If you have any blowing air in then you will be disrupting air flow in the case and bringing in more dust. Dust is a big risk for damaging components especially in humid places. Put all fans to blow out and see the big difference.

[@Sinjito]

What music at 1:57?

[@gucky4717]

Nvidia uses VERY squishy thermal pads. They are almost paste with a fibercloth in it to keep it togather. You can get those from Alphacool. They are called Eisschicht with 3W/mk. With OC to 600W 1,1V, +250Mhz on core and +1250Mhz on VRAM, my 4090FE runs cool even in my small case, if i ever have to test it. So why ever change pads? Of course i am not running it on 600W constantly, that isn't worth it. I UVed it below 300W.

[@8K240hz]

Hey my stock evga 2070 super's gpu hot spot reaches 99c while playing certain games. Basically just shooting my shot here, but a simple step by step gpu thermal re-paste tutorial for an evga card would be amazing coming from someone as skilled as you are. No problem if it can't be done, i appreciate your videos !

[@S3Bayaya]

I just did my first gpu repaste on sunday, after watching your video. After opening the heatsink and fan the board itself was so dirty I thought the card is fried. so much rust and soot. Turn out there are more than just changing the thermal paste. I don't know how to clean the rust on the heatsink and the port.

[@bjhe9068]

The original design had a thickness of 1.5mm, and the variation in the video memory position from 1.5mm to 1mm was caused by fatigue deformation of the PCB

[@Oceanborn712]

So... why does someone replace thermal pads on a 4090? That card isn't even a year old.

[@MetalWar04]

What did you use to clean the chip?

[@tony359]

I made this mistake myself, I had no idea the thickness of those pads was so critical!

[@siedliko]

I have used some random thermal paste on CPU and GPU before and I have switched to MX-5. Cpu went down from 80 to 65. Rtx 3080 went down from 84 to 64.

[@POLARTTYRTM]

What the hell, what would cause so many small parts to corrode so bad in a brand new card like that? That's insane. Does the owner lives just by the sea by any chance?

[@quintit]

From a few other comments I’ve seen, that appears to be a potential cause

[@chiyapet]

This is my card. I spilled coolant on it.

[@The_Man_In_Red]

@@chiyapet And that is why I love air cooling and undervolting. You get similar results but nobody ever complained their PC had too much ambient air blasting around inside it. I get it's not an enthusiast thing to do trying to push the limits of the silicon so I won't begrudge anyone who wants to do those things, it's just what I like.

[@chiyapet]

@pottingsoil723 Can relate after spending thousands of dollars on custom loop parts and days building a loop, seeing marginal gains, while nearly destroying a card in the process.

[@The_Man_In_Red]

@@chiyapet Admittedly it's a lot harder to keep modern CPUs cool on air without resorting to things like power limiting. Maybe if they ever figure how to install vapor chambers in a NH-d15 so there's definitely merit to cooling CPUs and keeping fan noise down with a loop or AIO. It's becoming truly insane how thermally dense CPUs are getting.

Buys a $2000 graphics card. Thinks a random eBay thermal pad kit can improve anything. When it makes it worse, recognize his own incompetence and sends it in for repair! Excellent.

[@ArtisChronicles]

​@@hugomatos1999 the i5 4670k I have actually runs better and a bit lower than stock after delidding it. It's been running fine for 3 years now. It's obviously not dead. Though I honestly can understand why you wouldn't wanna do it. The risk certainly is there. The stock thermal paste under the IHS really should've been a solder job so that the paste on your IHS would've been the biggest issue next to the heat sink choice.

[@South_0f_Heaven_]

I tell people this all the time. Little as 0.5mm too thick and this happens, usually easily seen if they just looked at the PCB as it will be warped after the GPU is put back together. Far as “Random eBay Pads” they do make pads with better thermal conductivity then what’s usually used by the OEM so can’t fault the person but the bone dry die is not excusable.

[@Tore_Lund]

@@hugomatos1999 Very wise words!

[@Ryan_DeWitt]

The engineers that do countless test and design these cards usually do a sufficient job with thermals for the stock specs of the card. Rarely do you see someone who went through a terrible amount of trouble to overclock something say they noticed a dramatic difference in real world use. However those synthetic bench mark numbers went up a fair amount.

[@South_0f_Heaven_]

@@hugomatos1999 did a delid and replacement of the material used on a 6700k that ran hot. Waste of time. People can say what they want about 80c-90c being normal but it’s not. Wasn’t that long ago CPU’s would shut the PC off if they hit 90c. Even if the chips do survive they are being severely kneecapped by thermal throttling at those temps.

Once I read the title I knew it was incorrect thermalpad thickness, but I was wondering why repasting and replacing pads on an RTX 4090? My GPU since 2018 (2080) and still running perfectly good no heat no issues! Repasting needed after 3-5 years of use! I bought a rusty 3080 and found that the first owner sold it as clean meanwhile probably he washed it by water to sell it as clean. The card has over 110°c in the hotspot and the pads were exactly like cement so I replaced everything now the core is 64c memory was around 65 now it is 74 because I did connected the separate heat sink to the main heatsink and maybe that’s why and the hot spot is 74

[@AwsBadr]

@@chiyapet well glad you got your card fixed :) Thank you for explaining to me otherwise I would be still thinking why repasting. Probably you used thermal grizzly pads they are one of the best if not the best, but extremely expensive as I bought some for my 3080 and ended up with less than what I needed just 3 memory pieces missing from the back side. An easy way to know how to choose the perfect thermal pad by using a clay or some sort of putty, place it and squish it and screw in your gpu and then unscrew and measure it. I had 1,2,3 mm so I just put the pads side to side with the putty and I choose the right one. Good luck and enjoy gaming

Next time you repair a 4090 FE or something with PTM7950 on it i would recommend looking into it and research options cos these cards if repasted with regular paste will never be as cool as they would be with PTM7950 unless something better exist, the PTM7950 is probably used to avoid pumpout cos these chips are very high wattage, uneven die or cooling surface can also contribute to pumpout, its expensive stuff but i would pay you good amount to put on PTM7950 on my card if you had to repair it or any other repair vendor, its probably best solution to overheating AMD graphics cards due their dies not being flat.
