Testing Method


My office is climate controlled. I keep the temperature at 20°C. Upon initial start up the PC was allowed to sit for 5 minutes to let the system temperature stabilize. Prime95 64-bit was then run on all cores for a total of 30 minutes. Temperatures were recorded at the end of 30 minutes. Core temp was used to monitor the temperature of the CPU cores. The temperatures for each core was averaged and used as our final temperature. Overclocking was achieved by changing the multiplier to 45 with a vcore of 1.25v. Turbo Boost was turned off for all tests. The stock test for the i7 4770k was performed at 3.5Ghz. PWM was disabled for the 100% test.

Stock processor speeds saw a maximum temperature of 44/45°C. The JetFlo fans dropped both idle and load temperatures by 1°C with less noise. Idle temperatures were barely above ambient. 45° is well below the 100°C maximum temperature set by Intel.

The Cooler Master Glacer 240L really performed well when we put some heat to it. The Blademaster fans barley out paced the JetFlo fans in our overclocked test. Idle temperatures ranged around 25°C and load temperatures never went more than 70°C.

  1. Hmmm

    It would be great if you could take Cooler Master at its word and actually utilize this cooler to its full potential.
    A very simple upgrade would be to add a POSEIDON-GTX780 with the OEM water cooler. It is should be very simple to add to this cooler. Run tests on both the GPU and CPU to see how how well the system can handle the additional load.
