Loud motherboard fan on Dell Dimension 9100

\015 My motherboard fan on my Dell 9100 Dimension is running at high speed, loudly. I replaced it with a new one, but I have the same problem, at the recommendation of a computer techie friend. Is there something else in the are of the fan that could be causing the noise?\015

Answers :

To much voltage coming from the motherboard which is why its running loudly, the ic's on the motherboard aren't controlling the amount of voltage coming into the fan which is why its running loudly. I would suggest another motherboard but I know they can be costly.

The other thing I would suggest though before the motherboard is try a different power supply cause that could be putting out to much voltage and also swap out the CPU could it could be not receiving the information properly and causing an overload.



Depends on the noise. Rattling: Ensure that all cables are out of the way and not touching the blades. Loud screaching noise: replace the fan immediately. now when you say mother board fan is it inbuilt?
