RV770 Debut - Radeon HD4850 CrossfireX ScalingHeat 'em Up!
Mounting pressure on the GPU is provided by a springy steel frame loaded with springs. Disassembly? Easy! Just a dozen screws needs to be removed. 8 of them are M2.5 and the remaining 4 holding the GPU are M2.
For overclockers on a budget who do not mind noise, and want that extra bit in cooling performance, a little elbow grease is all it takes to force the fan to spin at full speed. Remove the fan connector and locate the blue wire. This is the PWM control wire. Using a pair of tweezers, lift the plastic lip holding the contact, and pull out the wire. Once electrically disconnected, the fan will spin at maximal speed.
With fan control in place, it is indeed hot enough in 3D to warrant this sticker. Fan noise? You know it's there, but it's not glaringly obvious.
