a few days ago, i noticed my cpu was overheating, turns out the fan was running slow (500-600rpm instead of the usual ~1300). opened the case and cleaned a layer of dust from the fan/behind it, and now it doesn't spin at all - bios shows 'n/a' and speedfan shows 0 rpm.

the other fans are working fine, and the fan seems to try and spin during startup - it turns about 1cm and stops a few times

cpu's an amd athlon x2 240, cooler's an arctic freezer 64 pro, anyone know what'd fix it?

If you had to "clean a layer of dust" get a vacuum and go clean your computer... all of it... a lot..... repeatedly.....
