The HD4850 IceQ4 TurboX claims to be the fastest Radeon HD4850 card in the world.

IceQ Cooling System

HIS IceQ 4 is the 4th generation of HIS's cooling technology. Featuring double-slot fans and a larger heatsink surface area, IceQ 4 can effectively dissipate more heat from the GPU, thus allowing higher levels of performance.
The cooler is designed to expel air out of slots in the back of the card to prevent hot air from accumulating in the computer's case. IceQ 4 coolers allow clearance for a Crossfire bridge.
