Recently ive been having a number of computer woes, but the latest one involves my CPU fan. Whenever I try to turn on my computer my fan trys to spin up but fails miserably. It tries and tries, but never manages to spin up fast enough to keep turning. This is remedied however if I physically try to spin the fan, then it maintains a steady speed of about 400-650rpm. Now this from my eye's point of view looks VERY slow plus there is very little air flow actually coming out of the fan. What should I try to do to fix this? The PC doesnt overheat during general usage but I fear if I try to game on the machine ill break something. Ive thought about just buying a new fan but I dont want to do this unless this is all it can be, I dont want to spend £20 on a new fan only to find that it was a faulty connection on the motherboard. Cheers for any help.
