MSI GTX 1070 Gaming X High Pitched Buzzing

[TheMightyChris901]

I got my 1070 today and I have noticed a high pitched buzzing noise when playing games under high loads. I don't think its coil whine because its a constant buzz not a fluctuating one with different frame rates. If I put my ear to the top of the PC and put my fingers on alt tab, the moment I alt tab the buzz stops. Any Ideas what it could be?

P.S. I don't hear it unless I take my headphones off and nearly touch my PC with my ear so its not a huge deal and the cooler is certainly quieter than my reference 970 because I can't even hear it. But I am curious to see if anyone knows what it is. Thanks

The sound disappearing the moment you alt-tab makes me pretty sure that it's coil whine. If it were the fans vibrating or something, it would continue for a bit after you alt-tab as the fans need time to slow down when the GPU temperature drops. Coil whine isn't necessarily a fault, unless it really bugs you because it is unusually loud, but as you mentioned you can only hear it when very close to your PC so all should be fine

It's definitely coil whine, if you alt tab out of the game and it stops that pretty much confirms it. The MSI Gaming X fans turn on at 60 degrees Celsius, so an easy way to test it is let the fans turn off, immediately start a game that stresses your GPU or produces the noise, if the noise immediately begins, then it's coil whine. I actually have the same GPU and have slight coil whine under load.
