(Redirected) Alienware Aurora R5 PSU issue

Hey all,

I have some issue with my alienware, when the computer is not under load (watching youtube and netflix), the PSU fan randomly spin at very loud noise. The noise is so loud that i can even hear the sound from netflix or youtube. It got very annoying as the fan spin at max en stop suddenly and resume at random time at will....

Temperature is ok

cpu 33 C
Ambient Sensor 31 C
GPU 35 C
GPU Fan 27 %

It s alienware Aurora R5, I7 6700, 32GB Ram, GTX 1080, windows 10 pro, i believe it s a 460 W psu (or 480w)

Any suggestion for the issue? I have already run a full test and nothing come out...

Thanks for reply
