Fermi needs the thermal grease changed. I did it on mine and it runs cooler at load than the GTX 470 I have. Also, the high airflow bracket helps a lot on the GTX 480, the backplate is OK at best.
Changed TIM on both.
Idle @ 40% fan
480 w/ bracket and plate: 41C
Load @ 70% fan
480 w/ bracket and plate: 71C
OC @ 80% fan
480: 78C @ 850/1700/2050/1.062v (Faster than GTX 580 at stock clocks)
Pretty cool IMO. The bracket also reduces turbulence so noise levels are a lot lower also. 30-50% fan doesn't make a noticeable difference in noise levels. The GTX 400s are awesome cars if you're willing to tweak them a little.
Both used to heat up my room but now they both run cooler and removes heat much better.Edited by WorldExclusive - 12/30/10 at 2:25am
