HELP!!! Cpu fan stopped working!!!!

When i booted up my computer this morning, there was a screen that told me cpu fan error and i checked and the cpu fan wasnt working. i plugged the cpu fan into another 3-pin connector and it worked. Do u guys know whats the problem?

M4a79t deluxe motherboard
Zalman cnps 9700 cpu cooler
amd phenom II x4 955

no im not using the controller. well last night everything worked fine and the fan noise and everything is regular. its only when i turned it on today that the cpu fan doesnt work. i mean i plugged it into another 3-pin connector and it worked but there's a couple of problems:

1. i have another fan over there
2. right after the bios screen it tells me that the cpu fan isnt working even tho its physically spinning

Nope the power's dead on that socket. if i just leave that socket alone then i would lose 1 case fan and on top of that i would have a cpu fan warning everytime i boot up

RMA?

The easiest solution is to disable cpu fan warning in the bios and run the fan directly from the psu as mentioned before. However you won't be able to control it anymore. You don't have any spare sockets left on the mobo?

Yes you can use the fan speed controller but you need to be careful that your CPU stays cool.
I would not recommend running it off another socket in your board because it might try to control it based on NB temps or some such, and result in overheating.

And yes, you should open a ticket with Asus.
