The Gammaxx 300 is a CPU cooler from Deepcool. It has a tower heatsink, three U-shaped heatpipes, and a 120 mm fan. The Gammaxx 300 is the “smaller brother” of the Gammaxx 400, which we tested recently. This cooler is also sold under the name MC3002GX.

The Gammaxx 300 comes in a white cardboard box, as shown in Figure 1.

Figure 2 shows the contents of the box: the cooler itself, manual, and installation hardware. The heatsink seems to support a second fan, but it comes with only one fan and there are no clips for installing another one.
