My itx htpc sounds like a jet engine in my livingroom regardless of use.
I tried the "silent" setting for the cpu fan in the bios of my mobo (asus 61-i) but it changed nothing.
My cpu temps are around 55 and the fan RPM is constant around 2800. Task manager shows cpu load at 2-5 % when idle and the fan is still loud????
My cpu is an I3 2100, and i'm using a pico psu 120wide in a habey case. Connected is an ssd and a external usb tv tuner.
I'd like to be able to leave my pc on 24/7 but noise and heat are too much to handle.
