EKWB EK-Nucleus AIO CR360 Lux D-RGB AIO Review – Great Performance

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 since I can evaluate all coolers under 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.

Climate Chamber Technical Specifications:
  • Manufacturer: Giant Force
  • Model Number: GTH-800-20-CP-AR
  • Temp Range: -20℃ ~ +100℃
  • Humidity Range: 20% ~ 98% RH
  • Temp/humidity Constancy: ±0.2℃; ±2.5%RH
  • Temp/humidity Uniformity at center: ±0.5℃; ±4%RH
  • Indication Resolution:
  • Internal Dimensions (WHD): 100 x 100 x 80 cm
  • External Dimensions (WHD): 145 x 190 x 135 cm
  • Net Weight (approx): 450 kgs
  • Heat-up Time (No load, no linear): (from 20°C to +100°C) 30min
  • Pull-down Time (No load, no linear): (from 20°C to -20°C) 50min
  • Cooling System: Airtight compressor + evaporator fins + air-cooling condenser
  • Power Source: 3Φ AC 380V ±5%, 50Hz±1% 10KW
  • Based on Standards: ISO 5801-2007, AMCA 210-0, ASHRAE 51-2007, IEC 61591-2005, GB/T 1236-200

Besides the Giant Force climate chamber, I also use the following equipment.

Testing Equipment:
  • Noise Test Environment: Hemi-Anechoic Chamber with 6 dB(A) noise floor
  • Conditions: 25 (+-2) degrees Celsius, 40-50% humidity
  • Sound Analyzer: Bruel & Kjaer 2270-S G4
  • Microphone: Bruel & Kjaer Type 4955-A
  • Mic Calibrator:  Bruel & Kjaer Type 4231
  • Data Logger: Picoscope TC-08

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

Test System Specs
Mainboard Asus Prime Z690-A
CPU Intel 13900K Package Power Limit (PL1, PL2) set to 250W
GPU NVIDIA 1070 Ti
NVMe XPG GAMMIX S50 Lite 1TB
RAM XPG Lancer DDR5 (2 x 16GB) 6000MHz
Power Supply Seasonic Vertex 1200W
(Cybenetics Platinum)
CPU Cooler What is under test!
Case DimasTech Bench
Ambient Temperature 25°C ±0.5°C
Humidity 30% ±4%RH

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.

  1. Hi thanks for the review.
    I hesitate between CM Atmos and the EK Water Blocks EK-Nucleus CR360 Dark version.
    The fans are not RGB, the performance should be better?

    1. Both are very good. If I remember correctly the Atmos is slightly better in performance, but I like the true daisy chain of the Nucleus fans.
