Liquid cooling kit Alphacool XT45 Processor 12 cm Black Airflow 118.9 m³/h

The Alphacool XT45 Processor liquid cooling kit with a 12 cm Rise Aurora fan delivers a complete water-cooling solution for CPU temperature management. The kit combines an Eisblock XPX Aurora CPU water block, Core 100 reservoir with VPP Apex pump, NexXxoS XT45 full-copper 240 mm radiator, AlphaTube HF tubing, high-quality fittings and a high-flow quick-connect coupling. Included accessories such as thermal paste, premixed coolant, an aRGB controller, PWM and lighting cables, and installation tools make the set ready for immediate assembly and integration into desktop systems. The black finish and addressable RGB elements provide a neutral visual profile that fits a wide range of builds while maintaining performance-focused component selection with copper and brass metal parts for optimal heat transfer.

Advantages

The kit uses copper and brass for all metal components to ensure high thermal conductivity and long-term corrosion resistance in the water loop. The Eisblock XPX Aurora CPU cooler features a patented ramp system and a dense fin layout to direct flow across the CPU die area, while the NexXxoS XT45 full-copper radiator offers superior heat dissipation. The Rise Aurora fan combines up to 118.9 m³/h airflow and high static pressure with digitally addressable aRGB lighting and PWM control for flexible acoustic and cooling balance. A high-flow quick-release coupling allows adding or changing loop components without draining the system.

Suitable for

• High-performance desktop CPUs in gaming and workstation systems
• Custom liquid-cooling loops requiring modular expansion
• Builders seeking full-copper radiators and performance-oriented components
• Systems where visual aRGB lighting and a compact black aesthetic are desired

How to use

Install the Eisblock XPX Aurora onto the CPU using the supplied mounting hardware compatible with mainstream Intel and AMD sockets. Mount the NexXxoS 240 mm radiator in an appropriate case location and attach the Rise Aurora fans using the provided screws, connecting fans to the PWM headers and aRGB headers as required. Fit the Core 100 reservoir and VPP Apex pump in a convenient position, connect tubing between pump, CPU block, radiator and reservoir using the AlphaTube HF tubing and included G1/4" fittings. Fill the loop with the supplied premixed coolant, bleed air from the system, verify pump operation via SATA power and PWM signal, and check for leaks before powering the full system.

Usage recommendations

Ensure the loop is fully pressure-tested and bled of air before prolonged use. Use the included quick-connect coupling when planning future upgrades to avoid full drain cycles, and monitor pump RPM and fan speeds with motherboard or controller software to balance cooling performance and noise. Replace coolant according to manufacturer guidance and inspect fittings periodically for secure connection and signs of wear.
