EK Nucleus CR240 Lux White RGB Review

Thermal Testing - The best 240mm AIO that we have tested to date

When testing EK's new White Nucleus CR240 Lux AIO Liquid Cooler, we utilised our standard heatsink testing configuration which uses an Intel i9-9900K processor running at a fixed clock speed of 4.8GHz at 1.2V.

Using this hardware configuration, we tested EK's Nucleus AIO at various fan speeds using OCCT as our CPU test. We recorded the CPU's maximum temperatures over a 30-minute test run and recorded the data below. In this test, EK's Nucleus CR240 AIO proved to be the best performing 240mm AIO CPU that we have ever tested at least when the unit's maximum fan speeds are used.

Strangely, this unit's 1500 RPM tests gave us thermal results that were nigh identical to the 360mm version's 1000 RPM results, and the same is true when we compared the 240mm model's 2200 RPM test with the 360mm model's 1500 RPM results. If you want higher levels of cooling performance, EK's 360mm AIO model is the better cooler, but EK's 240mm version is no slouch. This AIO is a great option for PC users who do not own a case that supports radiators above the 240mm size. 

In terms of performance, EK's Nucleus CR240 Lux White RGB CPU cooler is the best performing 240mm AIO that we have tested based on maximum fan speed tests. However, this AIO does trade blows with ASUS' ROG Ryujin III 240mm AIO at lower fan RPMs. That said, the Ryujin III has a loud pump, whereas the EK Nucleus series has a near-silent pump, making it a better product for home or office use.
