I have a Dell T3400 deskto pc running win xp. When you turn on the pc the cpu fan is quiet but one the xp logo comes on the fan goes at full speed and sounds a plane taking off. The fan and heaksink have been reseated but this made no differance. I have read on the net that this is a quiet machine but yet a google search showed lots of people with the same problem but no answers. I have even tried flashing the bios to a09 but this made no differance. Help!!! Thanks Joe

Check your BIOS settings to see if "smart fan" settings are enabled or disabled.

If they are disabled, your fan will run at max speed all the time.

Once enabled, the fan should only speed up as your cpu heats up, and then turn itself down once a lower temperature is reached.

Dell Dimension 8250 ,FAN TOO FAST & Noisy but CPU COOL...


The fan settings can be found in the BIOS. On a Dell machine, when you turn the computer on repeatedly hit F2 until you are brought to the BIOS. Search through there until you find something named Acoustics, change the option to run at a lower level. Remember to save the changes before you exit.

Server starts to boot then powers off.


Check your CPU cooler. If it is not properly mounted your CPU/s could be overheating. There is a safety mechanism in Pentium chips that shut down the processor when it reaches a certain temperature. If your heat sinks are mounted correctly, check your Heat sink fans. Ball bearing fans are notorious for making a little noise then quitting.
