CoolerMaster's V8 heatsink is compatible with Intel 775/1155/1156/1366 platforms, and all of AMD's sockets, from 754 right up to the latest AM3. it is an impressive looking cooler with a high standard of finish.
The Cooler Master V8 features eight heat pipes, four sets of modular aluminum fins and an integrated 120mm fan, rated to dissipate up to 180w of heat. Heat Pipes are commonly used in high performance coolers now, and they work on the principle of condensation and evaporation. The 120mm fan incorporates Rifle bearings and operates between 800 and 1,800 rpm. The fan pulls air through one set of fins and expels through the other, cooling both. Most cases will have an exhaust fan in the area of the processor now to aid with the cooling performance.
At the hot interface within a heat pipe, which is typically at a very low pressure, a liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing the heat of that surface. The vapor condenses back into a liquid at the cold interface, releasing the latent heat. The liquid then returns to the hot interface through either capillary action or gravity action where it evaporates once more and repeats the cycle.
In addition, the internal pressure of the heat pipe can be set or adjusted to facilitate the phase change depending on the demands of the working conditions of the thermally managed system.
The fan can be controlled via the included PWM fan speed control adjustment knob which can be mounted into the PCI slot bracket (also supplied). It is fitted with a 4 pin fan connector.
