The Cuda enabled work puts my 2090tis right at the power limit. OpenCL was more likely to be around 80%.
I foresee alot of people finding unstable overclocked and power supplies with these high performance work units.

Only if CUDA and OpenCL WUs are mixed. If you only get CUDA WUs, you could OC for it.
Also, always cap the power on GPUs.

Are the cards running that hot because you're letting NVidia control the fan curves? If you don't intervene that's what NVidia will do - run them up to 82C.
My 1070s never go much above 25C over ambient but that's what water-cooling will get you.
I’m running Ubuntu 18.04 (can’t get things to work under anything later) and I seem to have limited control of things (or I’m just too ignorant). I think I could maybe force power consumption to 125W a card rather than the roughly 150W each they’re currently using. Maybe I can use the nvidia-smi command on a Linux terminal if that’s working (haven’t tried recently) to try to tweak some settings. The cards aren’t supposed to throttle until 90C and if neither goes over 82C, maybe I shouldn’t worry. Ambient is typically 25C.
I am running an Ubuntu variant, Pop!_OS. To enable fan speed control in Nvidia X Server Settings, I added the line
as the next-to-last line of Xwrapper.config. Restart the computer and set the fan speed manually. My Titan X runs at 65 to 70C with fan speed set at 85%.
You should try Pop!_OS. The Nvidia driver 525.85.05 is available in the Pop!_Shop but it will force you to install version 515.65.01 first. I am running Folding@home version 8.1.11 beta (recommended).
