Cooler Master GeminII CPU Cooler Review


Introducing the GeminII CPU Cooler

Cooler Master GeminII

Heatpipe tower coolers are nothing new, but the trend has coolers getting taller and having larger fins. Cooler Master has gone a different route with the GeminII. With their new heatpipe cooler they went short and wide, real wide, so much so that they have called it a CPU AND a Board cooler. The GeminII can also be used as a passive or active cooler as the end user has the option to install twin 120mm fans on to the GeminII. Lets look at the specifications and features.
