I installed my brand new Corsair CX650M today. At first I didnt notice anything. I played games for 3-4 hours and when I got my headphones off I noticed a weird sound. At first I tought they were from fans. I put my fingers in every fan possible (lol) but the sound was still there. My pc didn't have anything opened. Only discord and a few other things but not games. Is this coil whine? It's not annoying but I just know there is a strange high pitched sound. Help.
