I recently bought a new video card for my pc.
It's a Nvidia Geforce GTX 560 Ti with dual fans on it.
Now the problem is that the smaller fan on the right starts making a very strange ticking noise once in a while. It usually lasts for hours, and only stops when i give the fan a little flick. Then it goes back to spinning normally, without that sound.
I have taken the videocard apart, taken the big metal casing off to confirm it is not touching that. But even with the whole case off, it still make that noise. I can confirm that it isn't touching anything (as far as i can see). Also the fan is clean, no dust.
I prefer not to have to send my card back to nVidia as that would leave me without a working PC for too long.
