High Idle Temps

[Consoomer]

I recently built a computer with a 7700x and a arctic liquid cooler II 360 aio. I’m wanting to have near silent operation but I’m not looking to run my pc in another room with long cables to my desk. I was thinking what if I created custom fan curves using the asus software so that the case fans only spin if the cpu hits 80c with long delay in spin up time so if it bursts above 80 for a second it doesn’t kick them on. Basically they would never spin unless I’m actually doing something intensive for a longer period of time like playing a video game. I already have the cpu set to -20 voltage offset using bios pbo setting to help keep it cooler. It was unstable at 30. Seemed fine at 25 but I dialed it down to 20 just to be safe on the stability side.

 

Tldr

can I run my cpu at high idle temps constantly without damaging it?

 

Edit:

im currently running the pump at a constant 80% on the aio which I can’t hear and the radiator soaks the heat and stabilizes around 55c. When I do something like a quick download/software install I have seen it pop up to the 70s before going back down. So realistically it idles around 55c with no fans spinning just the pump going but I want to set the fan curve to 80 so they never kick on unless it’s a prolonged work load.

You shouldn't worry much about hight temps, the chip manages itself to keep max 95C, if it's too high for you crank it back in BIOS to 85C or whatever

Another option to keep temps down is to reduce somewhat max PPT, say 125W vs 142W stock, won't lose any gaming perf and maybe 5% in multithreaded/all cores perfs (test with CB23)

About fan speed, I suggest

- Pump speed 100% they're designed to work full speed

- case fans at constant say 40% (so they're silent) usually, with maybe one step up to 70% on hi temps (80C) but they may become noisy (depends on model)

- as for rad fans, a curve from 20% idle up to 50C/ 50% up to 70C/  80% above is usually ok, check if 80% is enough to keep a stable 85C max (but again above 80% fans tend to get loud)

On my 5900X it works quite well, keep temps below 80C and noise below 40dB (incl a GPU watercooler with 360 rad)

Focus on load temps, not idle temps. And more specifically, don't focus on temps at all and watch clock speed under load. Even more so with Ryzen 7000 that's the statistic that matters most. Throw a Cinebench load up and observe the all core clockspeed in something like HWiNFO or Ryzen Master.

Thank you for your advice. Running r23 for 10 mins with hwinfo the highest temp I touch for a moment is 94.1c on the ccd but mostly see it at 91c. I bounce between 5.225mhz and 5.325mhz all core. Voltage bounced between 1.22-1.36.
