GTX 460 beeping while Folding @ Home

Why is my GTX 460 beeping when running Folding @ Home for fermi? Version 6.30r2.

The beep is more of a silent non intrusive beep unlike the normal boot beep when you mobo boots up succesfully. The beep loudness is like 1/4 of a normal boot beep. And the beep is constant, one beep every second with beeps as long as 1 second.

I know it is my GTX 460 beeping because whenever i quit running F@H, the beep stops almost instantly. When i run it again, the beeps re appear. And F@H for fermi V 6.30r2 only uses the GPU.

I did try to search for the beep by opening my case and searching for it by ear to where the beep is loudest and yes it is coming from my GTX 460.

I did find another person with the same problem but he has a GTX 480. So it is apparent that GTX 400 series are beeping when folding. [...] 94&mpage=1

"Coil whine" or any sort of solid state hardware sounds were popular before manufacturers were still using electrolytic capacitors and coil chokes for video cards in the past. But GTX 400 series and any other 2010 cards are all built with solid capacitors and solid state chokes.

I dont see any monophonic speaker on my GTX 460 to reproduce a beep unlike what you can find on a motherboard. (that little thick black round thing with a silver hole in the middle, no not the cmos battery).

And my video card's temp while folding is just 61c while folding. But whenever i play games, the card reaches up to 79c without beeping. So its has not something to do with heat or overheating.

Anybody experiencing the same?
Why is it beeping despite all the solid caps and chokes on it?

Please someone help me be enlightened about this. Any advice will be greatly appreicated, thanks.
