My workaround for limited fan control via GPU temps was to just water cool my entire PC. I could have tied it to my water temp, but my components are rarely above 50C. I have two rads though, overkill for my 3080 and 3700X.

At least that’s my excuse, had to justify spending a dumb amount of money for cooling on top of the dumb amount of money already spent on the computer. Basically is spun up for a handful of Rocket League games and that’s about it.
