Hello, I made a thread the other day about looking for the right thermal pads to do a clean up on my graphics card and apply some new pads. Name of the cooler is in the title, I'm on a 2080ti.
Long story short that's what I did (I've triple checked the pads thickness too, I only ended up changing the pads on the VRM and they are 100% 1.5mm as stated by the manual), but now I just can't get my core temps right, they soar under any stress test and the card downclocks itself/system shuts down. My first guess was a bad paste application, but I've reapplied several times now (using MX-4 and Kryonaut).
Is it a matter of tightness on the backplate meaning that contact isn't high enough? I've tightened it to a comfortable degree (where I'm at right now) and the idle temps are mid 40s (compared to 20s before) with the aformentioned high temps and thermal throttling problem. Temps will shoot to 88c on a stress test with severe downclocking, and I'll just close the test down to save it rebooting. This to me speaks of a lack of good contact with the chipset but I just can't figure out what I'm doing wrong.
When I first put the card together over a year or so ago everything was fine, I had 20C on idle and mid 50Cs under load, I simply repeated the process in reverse and reassembled it and now I'm stuck with this issue. I think I've disassembled and repasted it 3 or 4 times thus far, I don't think I'm that incompetent with the paste for it to be the issue! I usually default to a decent blob in the center for it to spread once the heatsink comes into contact, but I've also tried applying it in a cross that goes across the chip for a shot at better coverage, still with poor results. When taking the card apart, it doesn't seem like paste coverage is a huge issue as the chip always seems to have a covering.
I tried tightening the card as much as it would go without damaging it, tightening all the backplate screws crosswise and going little by little more until each wouldn't go any further without any extreme force, and this resulted in the graphics card simply not working. The system would boot but I'd get no output, a loosening of the screws again allowed it to boot so I guess the PCB was was under stress from the cooler being just too tight.
I just can't find this middle ground for tightness for good contact and thermals, and not making the card stop working. I'm stressed and at my wits end here lol, any help would be greatly appreciated, thank you so much.

The thermal paste that you are using is one of the best on the market. If you give us a call we can disscus this issue on the phone. Is it possible to send or post some photos of your build ?
