To test the performance of the Cooler Master Nepton 240M, we built a powerful X79 based system on an open test bench to push the cooler to the limits.  As we were testing on an open test bench, we directed a Be Quiet! Shadow Wings 120 mm fan at the VRM circuitry to better simulate the airflow generated in a case.

For our extreme tests, we manually overclocked the i7-3930K to 4.7 GHz by increasing the multiplier to 47x, leaving the baseclock set at 100 MHz.

We set Load Line Calibration to ‘High', and increased the CPU Current Capability to 120% with a minor voltage increase.  Speed stepping was disabled for both stock and overclocked tests.

We tested the Nepton 240M with the fans connected to a 12V header on our motherboard.
