The Test System and Thermal Results
I would first like to thank ASUS, InWin, Corsair and Fractal Design for supplying products for me to test with. To see our testing methodology, and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article for that information.
As with all AIO testing, we set the pump to spin at full power, but there is no way to get an actual RPM reading, so we assume we were at the rated 3500RPM. With the voltage reduced to the fans, and the test run complete with them spinning at 1560RPM, the Glacer 240L gives results in the 48.5 degree average. While the Neptune is just ahead at this time, it does offer more surface area, and the fan's static pressure of the Glacer have yet to be set loose. For those interested, the CPU idled at 26.25 degrees during our runs.
Once the overclock was applied, the Glacer 240L shows up the entire crowd. While not by the largest of margins, it is still impressive that the Glacer 240L slightly outperformed its larger Nepton cousin. The fans were now running at 2300 RPM, and were delivering much more static pressure than almost any other fans I have tested, and allowed for the 67.58 degree average we seen here in this chart.
