Cooler Master Nepton 240M Test Results
As shown in the table below, the Cooler Master Nepton 240M was the clear winner in terms of noise and cooling performance when operated at full speed.
In the above test, the Corsair H100 was making so much noise that it would not be practical to have the fans running at that speed in a normal environment. The computer would need to be in a server room.
The image below is an FLIR infrared camera image showing the Nepton 240 cooler operating at 100% load. Despite the overclock and 100% load, maximum temperature shown by the temperature bar on the far right of the image shows a maximum temperature of only 52.5°.
After 45 minutes of stress testing with the Aida 64 benchmark program, the Nepton 240 maintained a respectable 56.4° average temperature with an ambient temperature of 28°. Despite careful thermal paste application and even pressure on the CPU cooler contact surface, there was still a core to core temperature variation of six or seven degrees.
Another FLIR image shows the top surface of the Corsair 800D case with the Nepton 240M fans operating at 100% capacity.
With a constant 28 degrees ambient temperature, the CPU very quickly reaches thermal equilibrium and has a very small drift upwards over the 45 minute test.
