Upto what temperature should I keep my case fans off?

[Farhan_]

Currently the case fans turn on only if the temp goes above 55°C at 60% fan power duty. By 60°C, fan power duty is 80% and at 70°C, fans run at max speed. Should I reduce the threshold? 55°C feels not too hot when I touch the cpu heatsink

80 degrees is max for most chips to really damage anything in the long term. 55 is fine

Thanks for the quick reply. Temp almost touches 75°c during prime95 and ~62°c during gaming. I'm good to go right? I just want my pc to be silent when idling

seems fine to me

really just depends on what you are comfortable with. ive seen cpu on stock coolers run at 100-ish °C in offices for years with no problem. gpu usually step down their clock way earlier though i believe the factory max they are trying to maintane is usually 70-ish? im not sure. 

id set up profiles and turn it up a bit when strssing and let it cook when idle. but thats just me.

well, knowing that the max temps for intel is 81,2 (or something around that) before it can damage by heat on the core, I really wouldn't recommend going over 80 degrees. but they can work a couple years on those temps, but especially for an office I wouldn't do it

not saying its ideal. just saying cpu's dont instantly die as soon as they go 1°C over. there usually alot of margin for error. also those office workhorses were pretty old machines. dont know if it has anything to do with it but maybe back then temp range was higher? idk

absolute temp limit is 105 on intel chips (most of them), well, a single degree can actually differ between 3 and 6 years, at least if we're talking all the time those temps. hitting 90 once doesn't hurt that much

Where'd you get that number? Intel cpus should shut down at ~100c before temps are dangerous.

It should be about the same but the quoted 'safe temp' of 80c is basically a guess. Killing a cpu from high temps isn't very common and it's more often from thermal cycling with temps going up and down repeatedly more than consistent high temps.

It was a certain value that came from a certain safe temp value (not fully remember, discussed it a while ago), I know that the throttle temps on intel is 95-105, but that wasn't what I'm talking about
