Otherwise it wil generate as much as it possible (f.e. in Crysis can reach even 5000fps - that what i have read) and to generate such many fps need many watts. So that why it make so many noise. I hope that will help you as well. Good luck lads
This is true. The screeching is louder the higher the frame rate. I turn Vsync on whenever I can with the 280, makes the screeching go away by keeping the frame rate at 60fps...
