NZXT Kraken X41 140mm AIO CPU Cooler Review

Test System Setup




I would first like to thank ASUS, InWin, Corsair, and Fractal Design for supplying products for me to test with.


To see our testing methodology, and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article for that information.



Thermal Results




Allowing the pump to run at full speed, we saw it range from 3700 to 4000 RPM, and even caught flashes of 4200 RPM at times. At this point, we are only controlling the clocks and the fan speeds.


With the stock clocks applied, we found the Kraken X41 falls into the average range with a 50 degree result here. Not too bad, as it does pass a dual radiator AIO, as well as most of the single 120mm versions on our charts.




Again, we allow the pump to spin as freely as possible, and received the same speed readings via the CAM software; this time, we let the fans lose as well. We can see where thickness and size come into play with over 100CFM of air flowing through it.


Coming in with a 68.03 degree average takes the X41 from average in the last test into ninth place over all. Considering all of the coolers that scored higher have much more surface area than this NZXT, we cannot complain about its level of performance.



Noise Level Results




With only one fan spinning this time, and considering it was spinning near 1300 RPM just like on the X61, the noise level drops ever so slightly to 28 dB with this version.




With the fans at full speed, and the CAM software as well as AIDA64 to confirm it, we saw a speed of 1900 RPM with 12V supplied. The X61 spun much closer to 2000 RPM, and with a slower fan, and only one this time, we saw 56 dB on our meter here.
