Deepcool Gammaxx 300 CPU Cooler Review

The Deepcool Gammaxx 300 (Cont’d)

On the base of the Gammaxx 300, the heatpipes are exposed in order to make direct contact with the CPU. This cooler comes with a layer of thermal compound pre-applied on the base. However, in this particular sample, it seems like the plastic cover that protects the base moved during transportation, and some compound was wiped off by the inner side of the box. First, we tested the cooler with its pre-applied thermal compound, which was partially removed. The performance was very poor. We then removed the stock compound, applied some Arctic Silver 5 compound, and retested. The cooler achieved better results, so those were the data we used on our comparison.

The 120 mm PWM-compatible fan is shown in Figure 9. As we mentioned before, the fan frame is conical instead of squared.

Figure 10 shows the heatsink of the Gammaxx 300 without the fan.
