We are testing today the Spire TherMax Eclipse II, a big CPU cooler with five heatpipes and two 120 mm fans. This cooler is aparently identical to the first version of the Spire TherMax Eclipse, which we reviewed some time ago, and both are very similar (for not saying identical) to the 3R System iCEAGE Prima Boss II. The first version of the TherMax Eclipse, however, has shown a far worst performance than the Prima Boss II’s. Maybe Spire released this second version to address this problem. Let’s test it and see if the performance of this CPU cooler got better.

The box that came with our sample was the same one used by the first version, but according to the manufacturer the final product will have "TherMax Eclipse II" on it.
