There seems to be a more specific issue with CPU temperature fluctuations in the game. I didn’t notice there was already a thread about this on the EU forums, so I made my own (which will probably be deleted now, because you know, duplicates) where I tried to give some more insight into the issue.
Nevertheless, I just wanted to add that I’m also having a problem with temperatures on my Ryzen 7 5800X. My temperatures are otherwise fine (in the 60°C to 70°C range) but occasionally they’ll spike up to around 85°C for a few seconds, which makes my computer fans go mental.
Makes playing the game a bit stressful when I have to be constantly monitoring my CPU temperatures to make sure my computer doesn’t fry itself.
