Keeping the same 450 W cooling capacity using only 2 slots, the WINDFORCE 3x 450 W cooling system is equipped with two 8 mm & four 6 mm cooper heat-pipes, inclined fans, & Gigabyte " Triangle Cool" technology. This not only provides an effective heat dissipation capacity but GPU Boost 2.0 technology also enables higher performance due to a lower temperature. Compare to reference 6-phase power design, this graphics card makes the MOSFET working at a lower temperature & provides more stable voltage output. Besides, over temperature protection & load balance to each MOSFET can effectively extend the card life.
