Axial-tech fan design has been enhanced with more fan blades and a new rotation scheme. Dual ball fan bearings can last up to twice as long as sleeve bearing designs. An all-aluminum shroud, reinforced frame, and metal backplate enhance durability.  MaxContact heat spreader features a super flat surface for improved thermal transfer.  A 144-hour validation program puts cards through a series of stringent tests to ensure compatibility with the latest games. A vented backplate prevents hot air from recirculating through the cooling array. GPU Tweak II provides intuitive performance tweaking, thermal controls, and system monitoring.
