My GPU fan suddenly stopped working. Everytime that i startup my laptop the fans are tested and i get an error stating that my VGA(GPU)  fan is not responding properly.

I know that the both fans work because from the alienware command center I can turn both fans on, but when i try to turn them off only the CPU fan turns off, but the GPU fans keep working.

I have updated my BIOS, but this dint fix the problem. Even during the BIOS update both fans were spinning.
