Sorry, that should read CoolerMaster, not mastercooler :-)

I  have a similar bit different problem, about three out of four times that

If you arent comfortable working on electronic equipment and have the proper
test equipment, I would suggest
taking it in for repair.    Otherwise, you can check the fan with a power
supply or even a battery to see if it runs.
You can hook up a motherboard to a power supply (a bench model or some
computer power supplies will work)
and then check  the voltages to be present or missing on the Motherboard.

The problem is entirely unrelated. Get a new fan, or oil the bearings
in the current one, if you know what you are doing. Yoiu probably have
a cheap fan using sleeves instead of ball bearings.

Therefor the fan works, the motherboard doesn't.

Yes, a few times with different boards. The problem may be that the
fan is asking too much from the power supply, they often limit to 300
ma. On the other hand it is likely that there is built in current
overload protection circuitry in the controller, so scratch that
theory. Back EMF from the fan motor may be a problem, but I am
guesstimating and to every guesstimation I can find a reason why the
guesstimation is probably wrong.

>Any suggestions for solving it?  

There is probably no solution other than replacing the fan power
supply/controller circuitry, and that is a decidedly non trivial job,
if it can be done at all.

Go to the top of the class! :-)

The advantage of the motherboard connection is that it is speed
controlled, but the fan may as well run flat out, that doesn't do any
harm except to aurally challenged cockroaches.
