* All new patented multiple support pressure vault bracket system, allow users adding pressure to the bracket system (40~70 lbs.), and have a more efficient and secure mounting.(1366 / 1156 / 775). * Mirrored copper base increasingly upgrade the quality and the performance of the heatsink. * Special bent winglet design, allows hot air to pass the heatsink more rapidly. * Heatsink are all nickel plated to ensure the best quality and performance and could last for years. * Soldered heatpipes, copper base and fins, to ensure the best thermal conducting efficiency. * Six sintered heatpipe design, all heatpipes are nickel plated.To slow the oxidation deterioration to the heatpipe, to ensure longer usage and performance of the heatsink for the cpu. * Including 2 sets of 120 x 25mm fan clips and Chill factor II thermal paste. * Convex copper base design, to ensure the Highest thermal conducting thermal efficiency between the cpu and the heatsink. Technical Spec Heatsink Dimension: Size: Length 127mm x Width 63mm x Height 160mm Weight: 755 g (excluding fan and bracket system) Heatpipe: 6mm sintered heatpipe x 6 units Copper base: C1100 pure nickel plated copper base, with ultra-shine mirrored surface.
