CPU fan issues

\015 Fan is noisy, comes on durin start up then stops, comes on intermitantly and is noisy\015

Answers :

The fan may not stay on all the time - its a feature of laptops to help save power. The fan is also variable speed. As the CPU gets hotter, the fan speeds up. When the CPU isn't being used as much and is cooler, the fan slows or even stops. It turns on to full speed when you first turn the laptop on as part of the BIOS system check.

The noise is another issue. You could have a broken "fin" or fan blade. The bearing could be going out. Something may have simply "crawled" inside the fan's output vent. In any case it may be worth your time to have a professional open up the laptop and look at the fan. I have heard a LOT of noisy laptop fans in my day, and believe me it's not the worst thing to put up with.
