Radiator Alphacool 11608

The Alphacool 11608 Radiator (Eisbaer Extreme Core) is a combined radiator and pump housing designed as the foundation for a custom water-cooled PC. The unit integrates a NexXxoS-style radiator enclosed in a high-quality housing together with a patented pump/reservoir combination and preinstalled Silent Wings 3 fans by be quiet!. The radiator is finished in black, constructed for efficient heat dissipation, and sized to fit multiple installation orientations inside a PC case.

Advantages

The integrated design combines radiator, reservoir and pump in a single modular housing, enabling compact system layouts and simplified installation. Preinstalled be quiet! Silent Wings 3 fans provide low-noise airflow, while the redesigned VPP755 Eispump with ceramic shaft and external motor coils offers improved stability and smoother operation. The unit is expandible and can be connected to additional water-cooling components or a CPU water block as required.

Suitable for

• Custom water-cooled PC builds requiring a combined radiator and pump housing
• Systems where low-noise airflow is important
• Setups that need a modifiable loop with room for expansion (CPU block or additional radiators)

How to use

Install the Alphacool 11608 Radiator into your PC case in a compatible mounting position either horizontally or vertically. Connect the pump and fan power connectors to the appropriate headers on your motherboard or fan controller and route tubing to your CPU or GPU water block and any additional loop components. Fill and bleed the loop according to Alphacool's standard water-cooling procedures, ensuring leak tests are completed before powering the system.

Usage recommendations

Use compatible fittings and tubing to match the radiator ports and follow the manufacturer's instructions for filling and leak testing. For quieter operation, connect fan headers to a PWM-capable controller and monitor pump speed via available control options to balance flow and noise.
