Too the moon and beyond

MasterAir G100MReminiscent of the Jupiter 2 from the 1960’s version of the TV series Lost In Space, the Cooler Master G100M 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.

Packaging

The G100M’s 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.

 

The cooler and the accessories are packed away inside a closed cell foam insert with cavities for the cooler and the accessories. The CPU cooler’s finish is protected by a thin plastic bag.

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?

  1. Your conclusion page is a little confusing when first reading it. The single graphic shown leads one to believe that the cooler does well (75 degree at load). Then you talk about the CPU throttling during testing. I think the graphic should be updated to clearly show that it is for stock speeds and/or a second screenshot showing the 100 degree throttle run with a label showing your 4.7 OC.

    This would greatly help to clarify your conclusion through both visual and written word.

  2. Thanks for the comment and suggestion. After looking at your comment, I do see how it can be confusing and I will be updating the chart accordingly.

Got something to say, then say it!
