Liquid cooling kit Alphacool ST30 12 cm Black Airflow 104.49 m³/h

The Alphacool Core Wind water cooling kit supplies a complete set of components to build a custom CPU water loop. The kit combines an Eisblock Aurora XP³ Light CPU cooler with a nickel-plated copper base, a compact Eisstation reservoir with integrated DC-LT 2 pump, a full-copper NexXxoS ST30 240mm radiator, two Eiszyklon Aurora LUX PRO 120 mm aRGB fans, clear AlphaTube HF 13/10 mm tubing and high-flow G1/4" fittings, Subzero thermal paste and ready-to-use Tec Protect 2 Clear coolant, plus an aRGB controller, cables and basic tools. Components are chosen for compatibility and performance; metal parts use copper or brass and the quick-release coupling enables adding radiators or GPU coolers later without draining the loop.

Advantages

The kit provides an optimally matched set of water-cooling components from Alphacool’s DIY range, prioritizing thermal performance with copper/brass construction for water-bearing parts. The Eisblock Aurora XP³ Light offers a dense microfin base and addressable aRGB illumination. The NexXxoS ST30 full-copper radiator delivers high thermal conductivity for efficient heat dissipation. The compact Eisstation reservoir with integrated DC-LT 2 pump reduces noise while keeping installation flexible, and the included quick-connect coupling simplifies later expansion. The package also contains thermal paste, premixed coolant and necessary cables and tools to start assembly immediately.

Suitable for

• Custom CPU water cooling loops for mainstream and high-performance desktop processors
• Users who want a ready-to-build kit with copper components for improved thermal transfer
• Builders who plan to expand the loop later (radiators, GPU blocks) using the quick-connect coupling

Key specifications

• Radiator: NexXxoS ST30 full-copper, 240 mm, two G1/4" ports plus fill/vent port
• CPU cooler: Eisblock Aurora XP³ Light, nickel-plated copper base, base plate area ~56 x 56 mm with cross-slot microfins
• Reservoir & pump: Eisstation reservoir with integrated DC-LT 2 pump, multiple G1/4" ports and a G3/8" fill port
• Fans: Eiszyklon Aurora LUX PRO 120 x 120 x 25 mm, PWM control 800–2000 rpm, 5V addressable aRGB
• Tubing: AlphaTube HF clear PVC, 13/10 mm (outer/inner diameter)
• Fittings: Eiszapfen 13/10 mm high-flow G1/4" connections and HF quick-connect coupling
• Thermal paste: Subzero thermal grease, thermal conductivity 16 W/m·K
• Coolant: Tec Protect 2 Clear, 1 L ready-to-use mixture

How to use

Install the Eisblock Aurora XP³ Light onto the compatible CPU socket following the mounting instructions for your motherboard and apply the included Subzero thermal paste to the CPU contact area. Mount the NexXxoS ST30 radiator in a suitable case location, attach the two Eiszyklon Aurora fans using the provided screws, and connect the fans to PWM headers or the included controller. Fit the Eisstation reservoir in a stable position and secure the DC-LT 2 pump inside the reservoir housing. Route the AlphaTube HF 13/10 mm tubing between components using the supplied G1/4" fittings, ensuring all connections are tight. Fill the loop via the reservoir’s G3/8" fill port with the Tec Protect 2 Clear coolant, bleed air from the system, and verify pump and fan operation before normal use.

Usage recommendations

Use the quick-connect coupling when planning future expansions to avoid draining the entire loop. Maintain coolant quality by checking levels and replacing the coolant per Alphacool’s maintenance guidelines; ensure electrical connections for PWM and aRGB are made according to the motherboard or controller documentation.
