## Summary description

The EK Water Blocks 3831109900178 is a black fan module designed for computer cooling systems. It features a 4-pin connector for easy installation and efficient airflow. Ideal for enhancing cooling performance in various setups.

## Long description

The EK-Nucleus AIO CR360 Dark is an all-in-one liquid CPU cooler finished entirely in black with no RGB. It features a slim 360 mm radiator and a triple-fan configuration, preinstalled reinforced rubber tubing with nylon mesh sleeves and aluminum covers, a dense microfin copper coldplate, and universal CPU socket compatibility including next-gen Intel and AMD AM5.
Advantages
The rotatable pump top lets you orient the EK badge in 90° increments so the logo remains aligned regardless of installation direction. Improved positioning of the rotary fittings and pre-installed reinforced tubing simplify installation even in tight cases. EK-Loop FPT fans offer high static pressure and a full-frame design for better airflow and are daisy-chainable via EK-OmniLink to reduce cable clutter. The copper microfin coldplate increases thermal transfer between the CPU IHS and the coolant for efficient heat removal.
Suitable for
High-performance desktop CPU cooling in gaming and workstation PCs
Cases that support a slim 360 mm radiator
Builds requiring minimal cable clutter thanks to daisy-chainable fans
Key specifications
Radiator size: slim 360 mm
Fan configuration: triple 120 mm EK-Loop FPT fans (high static pressure)
Connector type: 4-pin fan connector (fans with EK-OmniLink daisy-chain capability)
Coldplate material: copper with dense microfin structure
Tubing: reinforced rubber with nylon mesh sleeves and aluminum covers
Compatibility: modern Intel sockets and AMD sockets including AM5
How to use
Mount the slim 360 mm radiator into a compatible case location (top or front depending on case compatibility) and secure the triple fans to the radiator. Install the CPU water block onto the CPU following the included manual and the mounting hardware for your CPU socket. Connect the fans using the EK-OmniLink daisy-chain system to a single motherboard header or fan controller where supported, and attach the pump power connector to the appropriate header. Ensure tubing routing does not kink and that the rotatable pump top is oriented as desired before final tightening.
Usage recommendations
Use in cases that explicitly support a slim 360 mm radiator. When routing tubing, avoid sharp bends and allow slack for pump rotation. Use the daisy-chain feature to minimize header usage, but verify motherboard/controller compatibility with Micro-fit 8-pin connectors if combining with other OmniLink devices.
