Made of pure copper, the Dual Heatpipe VGA Cooler from Zalman ensures optimum heat dissipation. Featuring copper heatsink base and fins, it employs two high performance heatpipes to maximize heat transfer. Circular heatsink formed by radialy aligned ultra-thin fins minimize airflow resistance and enhance heat dissipation surface area for efficient cooling performance. A Fan installed in the heatsink not only cools the VGA chipset and VGA RAM, but also the other VGA components. Additionally, its light weight construction does not exert any excessive force on the VGA card. Moreover, it features an adjustable fan speed controller (FAN MATE 2) that enables control of noise and fan speed so that, you can 'power-up' your computer without worrying about problems due to over-heating.
