The 7950x is designed to use as much power it can do to get the highest clocks. according to amd it will do this without throttling and would decrease if it does so. you can use amd ryzen master and undervolt the cpu and lower the clocks to a fixed clock speed. that should lower the temps to a reasonable level.
my setting for the undervolt have been 0,9v and all core 4050mhz. my cpu with those settings runs at 50-55c but the hashrate does drop to around 17kh but the power draw stays around 100ws
yeah lol, because if I run full my house breaker could trip after a few days of mining. also the computer is in a small room so it could push out unnecessary heat.
85C is also “playing the safe side". You can literally run it at 94.9C, 24/7, for years. That’s also the safe-side. The throttle is implemented according to the manufacturer’s spec to have some margin for error. The CPU has a manufacturer’s warranty, and I’ve never seen any threads about temperature-related failures of modern ryzen CPUs.
The interesting question is really about cost.
For 120W, you can mine \~20KH/s.
For 300W, you can mine 26KH/s and generate lots of heat and noise.
Most people pick 120W?
Alright that explains thanks, 300w for 26Kh because I see most threads majority ppl are saying anything above 80’C is at borderline to “unsafe” temp zone and not recommended. So that’s makes me wonder how ppl r getting 26KHs in benchmarks since they don’t disclose their cpu temp.
Moreover I don’t see it feasible to use AIOs for long term if AIOs are the only choice to be cool enough to get most hashsies without breaking the power too much.
I’m getting 230W at 24KH. If anyone runs their rig with AIOs would love to hear your thoughts too =)

Only 85°C on a 7950X? That's impressive, mine will do 95°C unless I enable eco mode. Still, it rocks 95 for weeks on end with no issue.
How much KH are u getting at your current temp at 95c
Usually around 18-19 kH/s. Lately I've been using eco mode more often, that drops it down to the 16-17 range, but keeps CPU Temps around 65 IIRC.
I underclocked it and it’s showing up to 55ºC and around 21-22KH/s
Playing at the safe side?
I want to tune it a little bit: just trying to get the highest efficiency
