Scythe Musashi VGA Cooler Review
 

I was very impressed with the cooling performance of the Scythe Musashi. Furthermore, by using the fan controller, the right fan speeds can be set to match performance with silent operation. However, if you want to use another fan controller or you simply do not want to use one at all, you will still need to leave the provided controller in the case, as it can't be disconnected from the fans. Due to the wide range of graphics cards it is compatible with, most PC users will be able to install it on their cards. The cooler is compatible with the ATI HD4800 series, though the GTX260 and the GTX280 from nVidia are not. To attach the heatsink, a backplate is provided, which has a small rubber cushion right in the middle, so the pressure is really put on the GPU and not on the PCB.
