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. Let’s look at the specifications and features.
