Enermax Liqtech 240 Liquid 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.



Thermal Results




At the beginning of our testing we look at the idle temperatures, and this Enermax sat at 26.25 degrees after some time of sitting doing absolutely nothing. We do leave the head unit at full speed for all testing, and that registered at 2566 RPM most of the time.


Once we got to the load testing, we find the 49.5 degree result to be very good. Getting into the top five is not easy to accomplish, but the Liqtech 240 has gotten there.




With the overclock now applied, the idle temperature slightly climbed to 27 degrees. As we got to the loaded testing, we find that this cooler is somehow a bit lacking.


With all of that air flow and pressure, we would have expected this to be the best AIO on the market at 240mm, but we find the 71.5 degree average result a little confusing, as well as disappointing. Even after many remounts of the head unit, three tests in each orientation, and even being sure to get the radiator higher than the block, we did not see any improvements more than a degree, give or take, from each run.



Noise Level Results




Powering this pair of high performance fans with only 7.5V does result in some audible noise; even with the RPM down near 800 RPM, we were finding the 37 dB noise level. This is expected really, since the 12S is at the same level with the same fan.





Once we allowed the fans to stretch their legs, reporting 2547 RPM, we found these fans to be downright obnoxious at 68dB. Even in a sealed chassis with sound deadening materials, you are going to hear this cooler with this sort of power to it.
