NZXT Kraken X40 Review

For our temperature tests we loaded the system for 10 minutes using Prime 95 and recorded the CPU temperature using CPUID HWMonitor.  We then restarted the system and left it idling at the desktop for 10 minutes before recording temperatures. The temperatures recorded are based on an ambient temperature of 20 degrees C.

The thermal performance of the X40 was impressive in our tests, offering similar results to the H90.

Obviously the results were slightly different thanks to the fan speed profiles defined within the software.  When in ‘Silent' mode, the cooler wasn't able to cope with the large overclock we applied, resulting in the system crashing around 2 minutes into the test.
