EKWB EK-Nucleus 240mm Lux D-RGB AIO Liquid CPU Cooler - Desktop Overview 1

EK-Nucleus AIO CR240 Lux D-RGB

Addressable RGB Lighting

Customize your all-in-one system to match your setup with its fully addressable RGB lighting effects. This closed-loop liquid CPU cooler offers a plug-and-play solution with a fan-like D-RGB lighting effect around the pump top for all who search for that perfect RGB AIO aesthetics.

This product is compatible with popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin LED connector is to be aligned with the +5V marking on the addressable RGB (D-RGB) header.


Rotatable Pump Top

The top allows you to re-orient the D-RGB EK badge no matter in which direction the cooler is installed. The orientation can be changed in 90° increments, so if the cooler is installed upside down, rotate it 180 degrees to display the logo right side up. Regardless of the angle needed to install the AIO, it will always offer clean and aligned aesthetics.

New Positioning of Rotary Fittings

The AIO CR240 Lux comes pre-installed with reinforced and sleeved rubber tubing, now featuring finer threads. The fittings are covered with an aesthetic black radiator cover at the connection of the tubing and the radiator to ensure a sleek design and flushed line with the added fans. The improved position of rotary fittings on the other side, which are now placed next to each other, allows the EK-Nucleus AIO to be installed in even the tightest spaces.


Universally Compatible and Easy to Install

All EK-Nucleus AIOs come with a universally compatible CPU water block, fitting all the latest Intel and AMD CPU sockets. The installation process is very straightforward, thanks to the included manual and mounting mechanism. This product requires enough space to mount a single slim 240mm radiator, making it compatible with almost all modern cases.
