For 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.
These temperatures reflect almost exactly what we would expect from the Nepton 240M. They are similar to competing coolers, although can't quite match the performance of the comparable Corsair H105.
