I'm currently running AMD Athlon 64 FX-55 proccessor. Recently i've been noticing that the CPU fan (that came with the proccesor) sounds like its under alot of stress. I'm currently/nor have I been overclocking anything in my system. I don't really leave my pc on for long periods of time maybe a day or two then I turn it off.... The loudness of the fan is the worst when I first start my pc, sounds like its going to fly away or something. Any help would be apperciated, thank you
