or Pulse Width Modulator-related switching circuitry
(power supply stuff). usually these have switching
frequencies above human hearing @ 20 kHz.

also i skipped the class on how subharmonics are
generated.

open the window & let the bats & the dogs listen.
there might be a whole symphony going on & you
can only hear the part below 20 kHz.

I think it's normal, mine makes the same noise under load. Not a fan noise, but a high-pitch osillation type noise. Comes from the digital circutry, gpus, whatever. I think it's normal. Crank up the speakers a little.. :thumbsup:

thanks guys..i did some research and also called up powercolor and the engineer told me it is normal as most of the power hungry cards have the same issue..and i have affirm with quite a number of my friends..

So does this noise drive you crazy?

well if there is a way to solve it i rather it not have sound.

It has special fans that try to suck more money out of your wallet.

Inductor sing/coil whine - fairly common with these things. I made a recording of my 8800 doing it when stressed out and it was creepy.
