ZALMAN CNPS8X Optima 100mm Long Life Bearing HIGH PERFORMANCE CPU COOLER

Flow efficiency has been maximized by increasing the Air pressure via chamber formed between fan and the heat-sink and distributing it equally throughout the entire heat sink. Heat sink's bumpy shape has shortened the Air movement distance between the fan and the heat pipe, thus minimizing the efficiency level differences between the heat pipes and increasing the heat transferring function via speeding up the hot Air flow. Dimension: 110(l)x81(w)x148.5(H) / weight: 375G / Material: aluminum / fan bearing: long life bearing / fan: 100mm / noise level: 18.2 30.0dBA 10% / fan speed: 1,200 2,100 10% / PWM / 4 pin / input VOLTAGE: 12V Intel socket 1156/1155/1151/1150/775 & AMD socket FM2/FM1/AM3+/AM3/AM2+/AM2 100mm Shark fin blade fan is optimized for Air flow and therefore it drastically decreases the Air turbulence that is caused when the fan is operating. It also minimizes the noise and vibration and increases the fan power. Flow efficiency has been maximized by increasing the Air pressure via chamber formed between fan and the heat-sink and distributing it equally throughout the entire heat sink. Heat sink's bumpy shape has shortened the Air movement distance between the fan and the heat pipe, thus minimizing the efficiency level differences between the heat pipes and increasing the heat transferring function via speeding up the hot Air flow. The slit fin optimized for movement reduces resistance of Air flow and covers wider surface area for heat transfer, which allows maximized heat sink function. By distributing the Air that is derived from the fan and not the hot Air from heat sink, it cools down the surroundings of motherboard and provides more stabilized system. Direct touch heat-pipe (DTH) base technology transfers the CPU's heat directly to heat-pipes, there by minimizing heat resistance and maximizing cooling performance.
