Is a 20c delta between gpu and gpu hotspot bad?

gamecat · Sunday at 19:04

I've been out of the building game for a while, but recently built a new PC and have been messing around with overclocking and watching videos.
A recent Jayz2cents video showed him getting concerned about a 20c delta between his gpu and gpu hot-spot, with him taking the system apart to fix the problem.
My system has exactly that. It's cooling itself fine, with a full load pushing the hotspot to around 80c and the gpu sitting around 60c, which I had been happy about, but now I'm concerned. It's a 4080 super OC and only a couple of months old, so it shouldn't be developing issues just yet should it? Even with a modest overclock.

My gpu hotspot is 5'c hotter than the main temperature. I've got thermal grizzly paste on it and a waterblock. If I take it apart again I will replace it with a themalright heilos v2 pad (it doesn't degrade over time, same as thermal grizzly cryosheet but that's electrically conductive). I might just upgrade it though with a 9070xt and waterblock. You're right though, a two month card shouldn't have a hotspot that out of whack.

Pretty normal I say

I don't think I'd worry about it, but keep an eye on it and maybe take action if it keeps creeping up.

From what I've read 20°c is higher than average for an Nvidia card, but my 6800 XT had that from day one and ran fine for 4 years until I upgraded a couple of weeks ago.

Not sure if anyone else is interested, but I found this article over at Tom's Hardware, and it could be that Nvidia (or at least their partners) are cutting corners with the thermal paste.

Nvidia GPU partners reportedly cheap out on thermal paste, causing 100C hotspot temperatures — cheap paste allegedly degrades in a few months

Most (if not all) AIB partners allegedly use this dirt-cheap paste that looses performance in months.
