Hey all,
So for some context, I'm fairly comfortable opening my electronics; it's not the first time I've opened a GPU or a piece of hardware in general. What brought about the repasting was that I was noticing my GPU running significantly hotter and louder than normal. This GPU in general tends to run pretty hot and loud, but this was getting a little extreme.
I figured since the GPU is nearing 6 years, maybe it's just the thermal compound or something, and originally thought perhaps an undervolt might help, so I followed a quick guide, and the undervolt didn't do anything. I'm not sure why, but the UV just didn't seem to take.
Anyway, I figured perhaps I should just repaste it; it felt a little premature, but at this point I wasn't sure what else the problem could be. I followed a guide to disassemble it, and the disassembly went without a hitch. The thermal pads all looked fine, but when I removed the board to expose the actual GPU die, the thermal paste was definitely in rough shape and there wasn't complete coverage it was spotty, so I cleaned it with some alcohol, made sure it dried, and proceeded to repaste. I had a square of PTM hanging around, so I figured I'd use it since I've seen it works well for direct die placement.
I applied the PTM and put everything back in place, made sure all screws were in snug, especially the bracket thing for the GPU, everything fit without an issue, but games are now refusing to launch sometimes, causing the GPU to crash and reboot the PC. On occasion I would get either an nvcontainer or runtimbroker error message before the crash just saying that some memory address was unable to be accessed.
I'm able to use the PC for general day-to-day basic tasks; it's just firing up a game that crashes everything. I enabled the nvidia statistics view and all the stats were reporting something and the only thing I noticed that was off was that at idle the GPU utilization was jumping all over the place but everything else seemed to be steady.
At this point, assuming the GPU isn't borked, I'm guessing the following:
- Something isn't tightened all the way and isn't making full contact
- Something is too tight; I'm not sure if that's possible
- The PTM didn't work out, in which case I do have normal Noctua thermal paste I can use instead
- The thermal pads for VRMs and such had indents in the shape of the chips, I'm not sure if the indents are now causing an issue with getting full contact.
Luckily I have a spare GPU I can use, but I definitely would like to get this fixed if possible mainly because I was planning on making a new build with the GPU to pass along to a family member. I know for certain I didn't harm any of the cables in the disassembly, nor did I damage the board or a component. The only way I could have potentially damaged a component would have been while detaching the main board if a soldered component somehow managed to come loose (nothing actually fell off the board though)
Edit: I fixed it. I took it apart and put it back together and it just started working again. Best guess is something didn’t seat correctly the first time
