About a year ago I could run BF3 on high at 60 frames a second quiet as a mouse. Then I switched to using a 32 inch TV as my monitor from a 22 inch computer monitor. During that time when I played any games that have decent graphics my GPU would get very loud and I'm now using my tiny 22 inch screen and it's still making the loud noises. I went to play LOTRO and even when I have the settings at their minimum my GPU freaks out. I have a Nvidia 550ti. I should also mention that I clean every part of my rig and make sure it's free of dust every 3 months.
