What does the hotspot temp on the a 3080 FTW3 indicate exactly?
Mine is Watercooled with a Bykski block and has been for like a year.

I've noticed a few random crashes lately (mainly during playing FF7 Remake), just black screen/sound keeps playing but picture doesn't return, have to hard reset the PC.

I had Afterburner open and temp sits around 65Degree's (hot 31Deg day today in Australia) with zero offsets on speed/voltage/etc, all stock settings.
So i opened GPU-Z instead and immediately saw PerfCap Reason as Therm.

Everything is great, all sitting around 50-60 degree's across all the ICX gpu/mem/pwr temps, but Hotspot is reading 102-105.

Now my cards been mounted to the waterblock for quite a while and i've been waiting for a water distro plate for my Core P5 case to turn up so i could drain it all/remount everything/fresh coolant. 

Could it just be simply a thermal paste issue, or since everything else is in a nice range, am i looking at a card issue?

I dont ever remember the hotspot being much over the regulard gpu/gpu2 temp sensors or ever having a therm performance cap reason even when i mucked around OC'ing it under water

I'll have to repaste it before all the new gear turns up and see that fixes it.....
