EK-Nucleus CR360 Lux White – Simply gorgeous liquid cooler

Spectral analysis of noise

I probably don’t need to introduce EK Water Blocks here. It produces high-end components for water loops and for the last few years it has been using its experience in this field in designing AIO coolers as well. The EK-Nucleus CR360 Lux represents the top of the current range and will impress you above all with its clean and elegant design. With good test results, one can expect an attractive ratio of price, quality and efficiency, considering its price.

Spectral analysis of noise

Spectral noise analysis cannot be missing either. This is a simple analysis at noise levels of 39 dBA, 45 dBA and at maximum speed of the cooler. For the analysis I use the UMIK-1 microphone from miniDPS in conjunction with True Audio’s TrueRTA application. The resolution of the analysis is 1/24 of an octave and the shape of the spectrogram is an average of 100 samples acquired over 20–30 seconds.

Out of interest, I also added spectrograms of the cooler in combination with a trio of Noctua NF-A12x25 chromax.black fans, with which I ran a second set of tests with the cooler at 210 W TDP, because I was a bit disappointed with the acoustics of the supplied fans. With the high-end “sterrox” fans there was not only an improvement in the sound of the cooler, but logically also better results at normalized noise levels. The supplied EK-Loop FPT 120 D-RGB fans do achieve high static pressure and high flow of volume of air per unit of time, but this is at the expense of acoustic optimization, making the fans quite noisy in the upper speed range.

Scythe Mugen 6 (Black Ed.): Does a second fan finally make sense?

I give Scythe coolers less attention here than they really deserve. Today I’d like to remedy that, so I’m bringing you a double dose of Mugen 6 and Mugen 6 Black Edition cooler tests. The only difference between these coolers other than the color scheme is the presence of a second fan in the case of the black version. Given their design, I have high expectations for efficiency and hopefully I will be satisfied with the acoustic performance as well.

PCCooler CPS RZ820: Against the elite, weighing over 1.8 kg

They were so emphatic about their cooler being optimized for Intel LGA 1700 processors that we had to try it out. And given that the CPS RZ820 is a “hefty chunk” of material, the reference sample selection included the kind of competitive coolers that are at the top of the tower model database. These should give the PCCooler CPS RZ820 a good run for its money. At the same time, this cooler should not be more expensive.

DeepCool Assassin 4S – The stealthy tamer of high temps

A year ago, the excellent DeepCool Assassin IV cooler was tested here and eventually took our top award. Today we take a closer look at a modified version of this cooler called Assassin 4S. This variant may have lost the rear fan, but the middle one has been completely redesigned to compensate for this loss. So today’s article logically aims to find out how much of an impact this major change has on efficiency and acoustics. Read more “DeepCool Assassin 4S – The stealthy tamer of high temps” »
