As our trend into system cooling continues, this time I will take a look at the graphics sector. Most individuals already know the importance of overclocking, and keeping the system cool is one of the more important tasks in this day and age, given the powerful devices each contributing to the overall heat buildup in our systems. This time, I will be taking a look at the ZM50-HP VGA Heatpipe Cooler. This cooler works by the use of a heatpipe, which is simply a completely closed pipe that contains a fluid. When this fluid is heated, it evaporates, and proper positioning of the pipe will allow the gas particles to move to the top of the pipe, warming the air around it. In doing so it loses enough heat so that it condenses back into a liquid, ready for the process to repeat itself. The warm air is then expelled by the exhaust fan, so an inherent advantage is that one less fan (meaning less noise) is used, provided that your card originally included a fan.
