iCooler x4 Cooling Technology

iCooler x4 features a high performance dual slot cooler. It comes with four 6mm copper heatpipes which transfer heat effectively from the GPU to the internal fins around the central fan. Thanks to the elegant design and smoothness of iCooler fan shroud, massive amount of cool air is drawn from the central cooler to cool down the internal fins and heatpipes directly.

Massive amount of air is drawn from the central cooler to cool down the fins and heatpipes inside	The fan shroud design optimize for air ventilation that enhance cooling performance

 

To provide the ultimate heat conductivity larger surface area, iCooler x4 features three 6mm copper heatpipes which extend directly from the powerful 4890 GPU core. Heat from the 4890 GPU can rapidly transfer through heatpipes to fins that extend beyond the cooler. The optimized iCooler fan shroud design allows air flow to pass in and out and removes heat effectively. Together with the VRM heatsinks, iCooler x4 provides a great cooling platform for HD 4890.

iCooler x4 excels in noise management and is 10dB quieter than reference cooler	iCooler x4 transfer heat out of the GPU effectively.
