Speaker squeel with SLI

[Devious]

Ive just added my second gtx970 and I am now confronted with a horrible high pitch squeal from my speakers. It does it a little on the destkop but is ear wrenching when a game is running.

As soon as I heard i remember having it before when I have used SLI in the past on this system.

Is there any way to stop is happening?
The top card is quite close to my soundcard, so could it be that?

Specs
MSI Z68A-GD65

2x msi gtx 970
Asus XONAR Essense STX sound card.
Coolermaster V850 PSU

cheers

Seemed to have fixed it by disabling my mic in recording devices (not that i have a mic attached). Not an ideal fix though as I will want to use a mic sometime.

Strange I get the samething from the misses when I add new GPU's and play games...
