NZXT Kraken X41 CPU Cooler: Performance Test 1
Our first CPU Cooler Performance Test takes use of the included TIM and fans included with each CPU cooler. The NZXT Kraken X41 includes only one fan for a push setup and with pre-applied TIM which can only be used once. The purpose of this test is NOT to prove which cooler is better, but rather to give our readers an expectation of what to expect from each cooler using the stock fans and TIM.

Test 1 Results
The NZXT FX V2 140 mm fans have a measured RPM rating from 800 to 2000, although being limited to the Asus AI suite, our Gryphon Z87 motherboard only managed a minimum of 1100 rpm. The NZXT Kraken X41 outperforms literally every other cooler in this test at it’s maximum RPM, which is really impressive considering this is a 140 mm cooler.
Raising the CPU core of our I5 4670k to 4.2 GHz requires increasing the core voltage to 1.175 V. In our overclocked test the NZXT Kraken X41 still keeps our I5 4670k under control averaging 58.8 degrees Celsius. During this second run, we see other coolers take the lead. Compared to the Silverstone TD03-E, the Kraken X41 is beaten by it’s lack of a second fan, yet it sill maintains some really respectable temperatures across the RPM spectrum.
