Testing & Results
The Nepton 240M performance was evaluated against two other similar liquid cooling systems. The Corsair H100 is an older 240 mm cooling system, while the Corsair H110 is a new 280 mm cooling system. Published specifications for the three systems are shown below.

To be consistent, the same thermal paste was applied to each of the cooling blocks. The Arctic Silver Ceramique 2 paste was used for all three cooler installations.
Each product was measured for CPU temperature after running a 45 minute Aida 64 stress test. Because the test computer system has eight CPU cores, the average value of all eight individual cores was used for the final comparison. A digital thermometer and a FLIR camera were used to capture the ambient temperature during each test. Testing was performed later in the day when room temperatures had stabilized.
Noise measurements were also taken using a Galaxy Audio CM–240 SPL audio meter. Where possible, measurements were taken 1 meter from the center of the computer case. The CM–240 audio meter has a minimum SPL sensitivity of 32 dB(A) SPL. For measured values below 32 dB(A), the galaxy meter was moved to 500 cm from the source and the reading was divided by two. SPL values scale in a linear fashion, as opposed to sound intensity which has an inverse square relationship with distance.
Each of the three cooling systems was installed in the same test system as shown below.
The test computer system is a Intel i7-5960X based content creation machine with a modest 24/7 overclock of 4.2 GHz.
The Corsair 800D enclosure provides ample room for top mounted installation of the cooling system, and has good ventilation with 240 mm front fans and one 120 mm rear exhaust fan.

The Gigabyte x99 motherboard provides numerous fan headers for attachment to the liquid cooling system water block and fans. The BIOS allows setting the fans to 100%, or to be controlled through a Windows utility to an arbitrary percentage of the maximum speed.
In all test cases, the fans and pump of the cooler under test were connected to 3 or 4 pin motherboard fan terminals that were configured in the BIOS to operate at 100% speed.
