As mentioned in the title, I noticed that i one certain game which usually causes GPU to coil whine disappears after I minimize it first time. Though GPU usage grows from 40 to 50-60% after that. Didn't have anything like this in other games. Could it be normal?

I also have coil whine occasionally, and when I minimize the game, the whining disappears or reduces itself. I'm starting to believe that, it depends on the game, if you're playing for example cs go, in which you can hit 300-400 fps at least, your gpu will whine, my GPU whined even when the game was capped at 60 fps, or 75 fps, but sometimes does not whine at all.
But in return, one of my case fans started to whine, don't know why, but it does this whenever I play a game, but in idle is pretty much silent.
