I recently bought an MSI GTX 970 and it has started to make a very strange high pitched noise when GPU Usage climbs up. It starts immediately with the GPU Usage climb and is unrelated to the spinning of the fans. GPU voltage is a trailing indicator of the noise, obviously it's related to GPU Usage but it is not directly correlated with the sound.
As for the sound itself, imagine a tiny mechanical part spinning really really fast, like a centrifuge or the turbocharger in a car. It's very high-frequency, very high-pitched, and changes depending on what's on the screen. Although the best correlation is with GPU Usage, currently I'm running the Kombustor benchmark and the pitch of the sound is changing with the GPU Power % chart.
The existence of the sound does not change whether the video card is overclocked or not. Temperatures top out at 65 degrees Celcius.
Any ideas what could be causing it? Should I RMA the card?
