Test Methodology
I first install the cooler into a hemi-anechoic chamber, and with the help of a highly sophisticated sound analyzer, I take all necessary noise measurements required for the testing. Afterward, I install the system inside a giant climate chamber, where the ambient temperature remains steady at 25 degrees Celsius; this way, I don’t have to take the delta difference into account anymore since I can evaluate all coolers under precisely the same ambient temperature. I used to believe that taking the delta difference between the measured temperature of the CPU and the ambient temperature provided accurate results. Still, after testing with the climate chamber, I soon realized this was not the case.

For evaluating the coolers, I use a super power-hungry Intel i9-13900K. This beast is reaching 360W of sustained load, which I measure accurately using a Powenetics v2 system. All parts of the CPU cooling station test system are shown below. The thermal paste I use is the Arctic Cooling MX-4. I run at least two test sessions and take the average results.

The load application is no other but Prime95 (small FFTs), which applies a tremendous load to the processor. I run each test for 20 minutes, allowing for a 10-minute cool period between each test. The whole procedure is fully automated thanks to a particular application that I made for this purpose.
The critical point in my methodology for coolers is that I consider the CPU’s average frequency during testing because it doesn’t remain steady throughout the tests. It constantly changes according to the load and the operating temperatures. Moreover, I have the Powenetics system to continually measure the CPU’s power consumption, which is way more accurate and faster than using a software solution like HWinfo.
– Hope you’ll test “EK-Nucleus Lux CR360 D-RGB AIO” too (there’s also non-RGB (Dark version) and White version will be there soon as well…)
– It’s the best AIO in 2023 (according to many reviewers, such as Kitguru, OC3D, Robeytech and others…)
– Tech-Notice even showed it beats 420mm Arctic Liquid Freezer a bit when paired with 13900K… and some people commented that it’s just a couple degrees difference then with their Custom-loop cooling…
– And the AIO is finally in stock again (it wasn’t in stock for a long time, I guess people are buying like crazy haha – I also bought it, hope it will arrive soon :))
I just saw a review of “Phanteks Glacier One T30 Gen 2 D-RGB AIO (360mm)” and it’s 1 degree better then Nucleus Lux (on full load) – so you can test this one too 🙂
I am trying to find this AIO but I don’t have any contacts to Phanteks, unfortunately.
oh, that’s very unfortunate but what about EK-Nucleus? Could you review that one instead (while they are still in stock)? haha 😀
Will ask EK if they have any to send 🙂
Awesome 😀
There’s also new “Asus ROG Ryujin III 360” cooler that’s even better then these 2 coolers… but the pump noise is frustrating according to “OC3D”, and the price is also insane 😅
I will try to get that.
This AIO is the most suitable – especially in new generations of INTEL and AMD which are literally heaters.
Very good and tested by me on 13600K and 5900X.
I don’t like the desing of the PUMP that much, but that’s subjective.
As far as the noise is concerned, it is not one of the most silent when I tested it with the Arctic Freezer II 360 with 6 120mm fans, but also with the 2 processors the difference was an average of -4C compared to the Arctic Freezer II 360 with MX6 thermal paste.
The fans are very strong and DeepCool shows again in recent years that it wants to go 2 steps higher.
The DeepCool cases need radical renewal and redesign.
I should mention as far as the Fan Controller you mentioned (Corsair) is concerned, you can buy 10 seats from Arctic for €7 if you want to add another 3 for a push/pull arrangement and connect other fans.
Also, DeepCool, for someone who wants to change thermal pads on the GPU, etc., provides very high-quality mm pads in many dimensions.
Aris, goodevening! – We love you so much and we support you!
Bless UP! my friend
Thank you!!!
