I've had a Gigabyte GTX 580 SOC for a while now and every since day one, i have noticed a variable hissing noise coming from the card when under load. The hissing only happens with certain games.
The card only hisses when put under a specific load and the noise changes as i move the viewport around in a game and gets louder or quieter based on how much geometry the specific scene has.
I really couldn't be stuffed to RMA things because it takes ages to send things overseas from where i am. So could anyone who has experienced this be of assistance and at the very least explain to me what the hissing is caused by?
