Under normal load and generally "acceptable" FPS (I guess as high as 300), I noticed my Radeon HD 5570 and 7850 have no real issues. Whenever games and benchmarks tend to go into 1000, 2000, or even 3000 FPS, I notice both cards tend to make some noise, which from reading, I believe is coil whine.
Is this normal behavior for cards? As I mentioned, normal gaming and complex benchmarks don't cause any coil whine at all, it's only games with uncapped loading screens (GTA IV) and Triangle of Death (Kombuster) I notice that both cards will start producing coil whining, and usually the FPS is some insane amount too.
