GPU Whine?

Hey guys, so I have noticed recently that there is a whine or a squeal coming from my computer at certain times. When I run Minecraft, and click Multiplayer and it searches for servers, I start to hear a whine, almost like a kettle starting to boil, but not as loud. The same goes for when I click single player and it lists my worlds. Today I installed Hitman Absolution, and at the main menu, the squealing happens, more intense. In both these scenarios, the squealing stops the second I enter a world or start playing. I took of my side panel, and believe I narrowed down the sound to my graphics card. My build is only 6 months old, and I have had Minecraft on it since the start, but have only started hearing the whine recently. I have Googled a lot and found a lot of pages saying something about really high FPS causing it, but I'm not sure if that applies to me since it is only happening in the menu or at certain times. Any advice or thoughts would be greatly appreciated!
