17 R1, Windows 10, GPU fan not working

17 R1 GPU fan not working on Windows 10, yes on bios. 

Hello people, sorry for my bad English I'm not native. Since 12 weeks more or less laptop start getting hotter and hotter and I notice the GPU fan is always turned off.

I got a problem with GPU fan when I do the test on Alienware FN+ turn on gpu fan move, so slow but move.

I have try HWinfo, fantest and another 4 programs I got always the same problem, the no detect the fans. OR they detect both fans together and when I try to make them move only the CPU fan move.

I have upgrade BIOS alienware control panel center and everythings but still not working. I try a new game and  it is impossible to play that hot. I'm gonna broken the computer.

Any solution for this?
