I just opened my case and I realized that my fan on my cpu was slowing down and turning off for a couple seconds and back on. Some times it doesnt go totally off but slow then back up to full speed. And on my fan monitor it would not show the rpms then in a few seconds go back up. Any ideas :uhm: Specs are in my sig.

Either your power supply is going bad, or the CPU fan is starting to go out. I would test the fan by removing it from the computer, hooking up to a 12V power supply and letting it run. If it starts to slow down, then you need a new fan.

I went into the bios and found out that "Cpu smart fan" was enabled; thanks anyway mullet. Btw: should I keep it enabled or should I disable it?

I prefer to have mine running all the time. The choice is up to you, but the cooler, the better. I would turn CPU Smart Fan off.

Disable it, it is an option to reduce the sound your PC creates but usually the cpu fan isn't as loud as other parts of your pc anyway. Also, the cooler your CPU the more stable your system.

you definately dont want the fan shutting off at all... too much risk of the computer overheating and frying the processor core.

Only ever reduce fan speed if your CPU doesn't achieve scalding temperatures. For example, a Mobile Celeron processor (Which my laptop is blessed with - Joy roll%20eyes%20%28sarcastic%29.gif) will happily survive with the fan off for light work such as word processing and browsing the Internet (The BIOS will enable the fan if it starts to get warm, though), whilst a 3GHz Pentium 4 or a 2GHz Athlon 64 needs constant cooling to keep the chip from frying.

Indeed. Programs become more unstable and the system hangs a lot more at high temperatures so the lower and constant you can keep your CPU Temp. the better.
