Since today, my GPU fan has started making weird noises. It just stops in between sometimes and i have to rotate it by hand to make it start spinning normally again with that sound. Here's a video to show it.. help me guys .. its a sapphire hd6850.

I downloaded MSI afterburner and reduced the fan speed to 25% manually. The noise disappeared completely. As soon as I take it above 40, the noise returns back. I'm sure there is a problem with the fan because if dust would have been there then the noise will be present at all speeds!
Stress tested the GPU for 1 hour with 20% fan speed. Result >
