I would think that dropping the manual fan speed on a graphics card would always result in higher temps and a resulting lower framerate, but the following suggests that the card lowers GPU usage if the fan speed is much slower (to prevent overheating?) resulting in lower framerates that in turn prevent any chance of overheating.
Graphics: XFX Radeon HD 6870 2GB
Display setup: 3x1 Eyefinity (3430x1920)
Game: Crysis 2
- Fan speed: auto; FPS: 30-40; Load temps: 70-75C
- Fan speed: 20% via Vision Engine Control Center; FPS: 30-35; Load temps: 70-85C
- Fan speed: 0% via ATI Tray Tools (actual speed appears to be 10%); FPS: 15-20; Load temps: 60-70C
Does anyone know why my card isn't overheating at the minimum fan speed I can set?
