I seem to have a good GTX 1080 hampered by a crap cooler: a PNY XLR8. I'd always thought that was the end and have enjoyed undervolting and overclocking it as needed to match games but now that GPU-Z reports edge temps, I noticed something unique to this GPU:
Edge temps are 14C lower than hotspot temps.
On my Phoenix 1050 Ti, Gaming X 1060 6GB, Ventus 1660 Super, and Pulse 5600XT, edge temps are all only 8-9C lower than hotspot temps. These coolers seem to range from decent to great (edge temps stay under 70C @full OC) whereas the PNY 1080 is crap (edge temp can stay under 80C if fan is above 80% @full OC). All tested in the same case.
Opinions on whether this is due to a bad cooler fit or paste job from the factory? I've repasted CPUs and APUs (in NUCs) but never a GPU. I notice that the GDDR5 chips all have cooling pads to connect to the heatsink, so I assume I need to scrape those off and buy new ones if I detach the cooler to repaste. Getting this right is where I hesitate, what thickness pads should I get— 0.5mm more than measured gap?? I dunno. Because this GDDR5 overclocks like a champ, all the way to 12GHz, as high as Afterburner will go. I'd rather not lose that by being a repaste Neanderthal.
