Processor Fan Wont Spin, Sometimes


Recommended Posts

This is actually in regards to my bro's computer, i built it, and it seems like the processor fan sometimes wont spin, then ill touch the fan and it will.

but only sometimes does this happen.

 

It's an MSI mobo, intel stock cooler, on dual core proc.

 

any ideas?

windows xp

 

or is this normal, i thought maybe it only starts spinning at a certain temp, but it keeps his comp temp pretty low so i dunno?

it almost seems random.....

Check the bios and see if dynamic fan control is enabled. My board did that for a while until I disabled it(called smartfan on my board or something). Got really annoying with the 120 inside my Tuniq Tower constantly spinning up and down...

Most boards these days have some fan control built into the BIOS, you can either disable it or lower the threshold temperature to make the fan stay on all the time. With the stock cooler, it's probably best to lower the threshold temperature, because the fan is noisy at full speed.
