Gigabyte NVIDIA GeForce 6600GT with Silent-Pipe II
 

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.

Even without any cooling fan, we manage to overclock the card from 500/1000 to 552/1200 with rock stability. The idle temperature was 47.2 degree and 73.3 degree when loaded. This is well within safety level but you should ensure that your casing is well-ventilated too.
