Liquid Cooler Alphacool Eisbaer Aurora 240 CPU Processor Black

The Alphacool Eisbaer Aurora 240 is an all-in-one liquid cooler for CPUs featuring a 240 mm copper radiator, an integrated reservoir with refill port, and an improved pump assembly. The unit includes digital addressable RGB lighting on the pump housing and on the Aurora LUX Pro fans, TPV hoses and G1/4" fittings from Alphacool's Enterprise Solution series, and compatibility with Eisbaer-Ready quick-release connectors for loop expansion.

Advantages

The cooler combines a larger reservoir and refill capability with a redesigned DC-LT pump that delivers approximately 10% more performance while reducing noise compared to the previous model. All water-bearing components in the radiator are copper to preserve thermal performance, and the radiator uses a 15 FPI fin density to balance cooling efficiency with low airflow. The system features digital addressable RGB LEDs across pump and fans, and includes Y-adapters and a 3-pin 5V adapter to simplify fan and lighting connections.

Suitable for

• Cooling desktop CPUs in gaming and workstation builds
• Systems where loop expansion or custom components are planned (Eisbaer-Ready compatibility)
• Quiet cooling setups that benefit from an efficient 240 mm radiator and low-RPM fan operation

How to use

Mount the radiator and fans in your case using the standard 240 mm mounting points, align the copper cold plate to the CPU heatspreader and secure the pump/reservoir assembly to the motherboard bracket supplied for the supported sockets. Connect fans to a 4-pin PWM header; use the included Y-cables to run multiple fans from a single header if needed. Plug the 3-pin JST RGB connectors to a compatible 5 V ARGB header or use the supplied Digital RGB controller. Connect the pump to a 3-pin Molex or motherboard header as appropriate. If expanding the loop, use the Eisbaer-Ready quick-release fasteners and refill through the reservoir fill port as required.

Recommendations

For optimal balance of noise and cooling performance, set fan curves in your motherboard or controller to keep fans at lower RPM under light load and increase speed under sustained high CPU load. When expanding the loop, ensure fittings are tightened to the G1/4" thread specification and check the fill port for proper sealing after refilling.
