Before: System 45C Ambient (GPU) 47 GPU: 62 After: System: 37C ! 8C out of case, the "lid area" under your gpu. Ambient: 45C GPU: 60C temps @ load, 20min Crysis With GTX260 max oc'd, I found my 'System' temp raised quite a bit, from say 41C with G92 to 45C with GTX260, and after experienced few BSODs, I decided to do something about it. My plan was to get rid of all the PCI plates under the GTX260 and add a fan on the outside, sucking air from the case. Luckily I had the perfect fan: 100mm size from my HSF Scythe Mine..it's nearly ideal, 1cm too small on each side to have a perfect fit on the back of the Antec 900. So, put some cardboard box under it to raise the fan to DVI-port level on card. This very fan had a cord that JUST made it to nearest 3pin connector on my mobo, DS3R rev1.0....but eventually I added a Zalman Fanmate (coz 1500rpm sucked itself against the case, made irritating sound) for 1300rpm level. That cord is also LONG and I have it outside case for manual control.
