There is a high pitched sound when fans start to spin. Like a whistle. Snow informer midi. It's not very loud bit it can be heard. Ati radeon hd 3870 driver windows 10. The faster fans spin the higher/louder the sound. There is a normal sound of air being pushed out of the laptop and there is that high pitched sound, like a little, quiet turbocharger. Some component that is moving. The movement produces the noise. A great technician will know to SHELLAC any and all coils on the main circuit board to reduce that noise. There is one thing that really bothers me. There is a high pitched sound when fans start to spin. Like a whistle. It's not very loud bit it can be heard.

Hello all, I have recently purchased an HP Envy 17 Notebook Touch and there is a noise coming from somewhere on the inside of the laptop under the keyboard that is a super high pitched noise. I have done tons of research on how to stop this noise. So far I have tried disabling the idle processor but I failed.
Laptop Fan High Pitch Noise
I have a VERY annoying issue with my laptop. The right side (side with kensington lock) fan whines at low rpms, so during desktop use and non intensive games, it's all I can hear.
At high RPMs in intensive games the whine is drowned out by regular fan wind noise. The left fan is operating fine at all RPMs, no high pitch sounds at all.

I know 100% it's the right fan doing this. If i stop the right fan using 'notebook fancontrol' program, the whine goes away instantly.
I also think the dc brushless motor itself is defective and is producing the whine because it sounds exactly like coil whine and I think oiling the bearing wouldn't really fix it.
The sound is driving me mad, it can be heard from 3 meters away or more in a quiet room. So it's all I hear when using the computer, extremely disappointing coming from such an expensive laptop.
Anyone else have the same problem with one of their fans?
