EKWB EK-Nucleus AIO CR240 Dark Liquid CPU Cooler – 240mm Radiator

Product Overview

The EKWB EK-Nucleus AIO CR240 Dark is a premium all-in-one liquid CPU cooler designed for users who want high-performance cooling with a clean, understated appearance. Its completely black, non-RGB design makes it an excellent choice for stealthy, professional, and minimalist PC builds.

Featuring a slim 240mm radiator, dual-fan configuration, reinforced tubing, and a high-efficiency microfin copper cold plate, the Nucleus AIO CR240 Dark is designed to deliver efficient CPU cooling while fitting comfortably into a wide range of modern PC cases.

Slim 240mm Liquid Cooling

The EK-Nucleus AIO CR240 Dark combines a compact 240mm radiator with a dual 120mm fan setup to provide an effective balance of cooling performance and case compatibility.

Its slim radiator format makes it suitable for a wide range of popular PC cases while providing substantially more cooling surface area than traditional air coolers.

Rotatable Pump Top

The pump top features a 90-degree rotational adjustment, allowing the EK badge to remain properly aligned regardless of how the cooler is installed.

With four available orientation positions, users can rotate the pump top to maintain a clean and symmetrical appearance even when the AIO is installed in a non-standard orientation.

Reinforced Tubing & Improved Fittings

The EK-Nucleus AIO Dark features pre-installed reinforced rubber tubing covered with fine nylon mesh sleeves. Aluminum covers on the tubing add another layer of protection while contributing to the cooler’s premium appearance.

The improved positioning of the rotary fittings makes tube routing and adjustment easier, particularly in compact cases or installations where space around the CPU socket is limited.

EK-OmniLink Cable Management

The EK-OmniLink ecosystem allows compatible fans to be daisy chained together, helping reduce cable clutter inside the PC.

Using Micro-fit 8-pin connectors, OmniLink simplifies the connection of multiple fans while maintaining flexibility. Individual fans can still be removed from the chain when required, making installation and cable management easier.

EK-Loop FPT 120 Fans

The included EK-Loop Fan FPT 120 is designed specifically for high-performance liquid-cooling applications. Its full-frame construction helps minimize airflow escaping around the fan frame, directing more air through the radiator.

The fan’s high-static-pressure design makes it well suited to pushing air through the dense fin structure of a liquid-cooling radiator.

Dense Microfin Copper Cold Plate

The CPU contact surface uses a copper cold plate engineered for efficient thermal transfer. Its dense microfin structure increases the surface area available for heat exchange between the copper base and coolant.

This design helps maximize the effectiveness of the liquid-cooling system by providing a larger thermal transfer area within the cold plate.

Clean Dark Aesthetic

The EK-Nucleus AIO CR240 Dark features a pitch-black, RGB-free design, making it ideal for users who prefer a subtle and professional appearance.

Its minimalist styling works particularly well with black stealth builds, workstation systems, and performance PCs where the focus is on hardware rather than lighting.
