Reminiscent of the Jupiter 2 from the 1960’s version of the TV series Lost In Space, the Cooler Master Masterair G100M CPU Cooler is affectionately called the UFO cooler. The G100M is a low profile cooler designed to fit into smaller cases especially mini-ITX. The G100M boats a 130-watt cooling capacity and features a large “heat column” at the center of the cooler. With its small size and new cooling technology, does the G100M make sense in your daily driver?
What is the heat column? Well, to me it appears to be just a single large heat pipe that is used in multiple coolers. The cooling process is similar to heat pipes, the liquid inside boils and turns into a vapor. The vapor rises to the top where heat is transferred from the heat column to the fins of the cooler and the vapor re-condenses back to the bottom of the heat column and the process repeats. The one advantage is rather than heat pipes being soldered to a cold plate, the bottom of the heat column sits directly on top of the CPU’s heat spreader. In short, it is a really big, single heat pipe.
Cooler Master Masterair G100M CPU Cooler packaging is a simple affair. The packaging isn’t flash and the front of the box features a large clear image of the cooler contained inside. On the rear, Cool Master details some of the features of the G100M in 8 different languages.
While Cooler Master says the mounting kit is tool-free, that’s not really the case as they’ve included a custom wrench. in this case, tool-free means you don’t have to use your own tools. Included in the kit are a backplate and mounting arms for both Intel and AMD sockets, an RGB LED controller, and Cooler Master thermal paste. A Molex connector is included to provide power to the RGB LEDs. Molex, really?
