My CPU fan in my computer is pissing me off. Everytime the processor isn't idle, the fan runs at full speed. It's kinda loud and annoying. My housemates think there is a plane taking off in my room or something. Is there any way or any good software that can control the speed of the fan? When the fan is running at normal speed, it's quiet and I don't mind it. I just don't want it firing up everytime I play solitaire or open a window. Does the fan really need to be running so fast to keep the CPU cool?
