The special inclined dual fan design effectively minimizes the flow of turbulence between two fans and enhances heat dissipation of hot area right underneath each fan. By unique design, WINDFORCE™ 2X even enlarges air channel on the graphics card vents and creates a more effective air flow system in chassis. This special design helps heat dissipate quickly from GPU. In addition, WINDFORCE™ 2X is equipped with 2 copper heat pipes to strengthen the speed of heat dissipation.
