Gigabyte NVIDIA GeForce 6600GT, now with Silent-Pipe II technology, is a fanless solution for the enthusiastic gamers who want performance without noise. Unlike the traditional heatpipe cooling solution, Silent-Pipe II has a front-flow thermal module to create a natural system convection. Therefore a well-ventilated casing is necessary for the hot air to be removed by the PSU and CPU fans.
