would it be fine? just having the cpu fan on and the rest off.
my cpu idles and light workload between 26-30C depending on ambient
Yeah, should be fine. If your CPU fan is still on, you've got nothing to worry about.
Sure, it'll be fine as long as the CPU cooler is still on...but the real question is: "why?"
silence? less dust? :3
Good enough for me. Noise from computer fans has never bothered me, hahaha
most modern motherboards allow for a software/firmware version of Qfan or similarr that can control your fan speeds when connected to the motherboard, based on board temp, CPU temp, or CPU load. I have my ASUS baord set up for ultra-quiet mode, and unless the PC is really under load, you can't even hear the thing running.. CPU is liquid cooled with 4 120mm fans, another 120mm exhaust fan, and a 140mm top fan in an S340 NZXT case. The only time it's really loud is for a moment during reboot before the BIOS quiets the fans.
Hopefully it is fine i think.
