If my CPU fan is not spinning does that mean that the processor is not working? Or is it my motherboard?

if the fan is plugged in its either the fan or motherboard thats faulty.

there may be another connector on your motherboard that you can plug your fan into...

there may be afan2 connector or casefan connector you can use :)

it most likely means the fan is dead. You may just need a new fan on the heatsink. That being said, it could be your motherboard its power circuits shorted, the processor COULD be bad, but even if it was, the fan should spin up when you turn on the power.

its really wierd though because the case fans are all spinning and this one isn't.

by david.wallis

plug it into one of the sockets a case fan is in and see if it spins :)

it is by no means unusual for the CPU fans to die, especially if it is dusty.

If you can just unscrew the fan from the heat sink, then it is cheap and easy to replace.

If it is a custom heat sink, then you will have to replace the whole sink.

then replacing the fan on the heatsink is the way to go. Do a little research, some go out more often the others... you may have a bum fan on the cpu, or it may be dust and wear. Either way, simple fix, as JD has said.

If that specific fan plug is dead, you may need to cut a solder a longer cable to reach another header thats live.
