Is there any risk/downside to me under volting my cpu, other than the slight performance hit? My new build is running really hot - clocked it at 95C and the fans go mad and so after looking up some guides online i've changed the curve optimiser doodar to negative 30 and also limited the voltage. Now its running at 80c max and the fans don't sound like they are about to explode. Everything else seems fine and the performance hit seems negligible.

No risk to the hardware, just don't forget you did it if you run into any stability problems

It took me forever to figure out but cyberpunk has random gpu driver crashes on my system unless i run my cpu at stock, years ago my system was perfectly stable with curve optimizer at -15 in various stress tests and games (and still is) so i just set it to -10 to be on the save side and forgot about it. Never had the idea it might be the problem in cyberpunk until the intel cpu disaster with nvidia blaming intel cpus for gpu errors, so i removed the undervolt and haven't had a crash since.

I think I recall Hitman 2 (or maybe it was 3, time is difficult) started having seemingly random gpu crashes for me with an undervolted rtx3070, while all the stress and stability testing were fine.
It's entirely possible that if I had just goosed up the voltage a little bit while still undervolting it might have been stable again, but I never bothered to test thoroughly, rather just stopped applying the undervolt.
