Product information: **B Grade** NV4 Rev.2 (FX5950) VGA SilencerThe Arctic Cooling NV Silencer 4 is ideal for Nvidia Geforce 5950/5900 based graphic cards. It offers substantially better cooling performance over the nVidia reference cooler. With the Arctic Cooling VGA Silencer makes use of DHE (Direct Heat Exhaust) system. This carries the warm exhaust air directly from inside the case, thus the inside case temperatures are lower. By the large aluminum radiator box with copper base plate it needs only a slowly turning exhaust fan, in order to keep things cool. Thus operating at a very low noise level!
