GTX470 makes weird noise.

[sincere]

Hi folks,

my Hackintosh is completely functioning, but my GTX470 makes some weird noise.
I can't describe it very well. The noise is very annoying. I hope you can help me.

Regards

Uh... it may be difficult to articulate what the noises sound like, but without you trying I don't think you're going to get very far.

Ever listen to Car Talk?

may be it is chokes whistle on full hardware load?
sometimes chokes on hardware is not fixated fully and on high power passing through them they starting to vibrate on voltage frequency and making high pitch sound.

go to some hardware forum and read about this, there are many solutions about that.

Thanks for your replies guys.

I think choke whistle describes it perfectly. I didn't know how to describe it in English.
The weird is, that it is appearing from time to time. If I click on Parallels Desktop, the noise stops for 2 seconds and then it appears again.
I hope there's some software-fix for that.

Regards
