Jäähdytin Alphacool NexXxoS ST30

The Alphacool NexXxoS ST30 radiator is a slim, single-fan cooling component designed for liquid-cooled PC systems. Constructed from brass, copper and steel, the unit measures 144 mm wide, 313.5 mm deep and 30 mm high and comes in a black finish. Intended to integrate into compact or space-constrained builds, this 140 mm fan-compatible radiator offers efficient heat dissipation for CPUs, GPUs and other components that require liquid cooling.

Advantages

The combination of brass, copper and steel provides good thermal conductivity and structural durability while keeping overall weight low at approximately 0.855 kg. The slim 30 mm profile allows installation in tight mounting locations where thicker radiators would not fit. Compatibility with 140 mm fans and a compact footprint enable flexible placement options inside many modern PC cases. The black finish helps the radiator blend into dark-themed builds for a discreet appearance.

Suitable for (tasks / use cases)

• Compact liquid-cooling loops in small or mid-tower PC cases
• Single-fan radiator installations using 140 mm fans
• Cooling for CPU-only or GPU-only custom water-cooling circuits
• Builds that require a low-profile radiator to fit limited clearance

Key specifications

• Dimensions: 144 mm (width) × 313.5 mm (depth) × 30 mm (height)
• Materials: brass, copper, steel
• Fan compatibility: 140 mm
• Colour: black
• Weight: 0.855 kg (approx.)

How to use

Install the radiator in your PC case according to available mounting points for a 140 mm fan and connect it to your custom liquid loop using appropriate fittings and tubing. Ensure the radiator is oriented to allow proper airflow and to minimize trapped air within the loop. Mount a compatible 140 mm fan to the radiator using screws designed for radiator-to-fan mounting, and route fan power to an appropriate header or controller. Fill the loop, perform leak testing, and run the pump at recommended operating parameters before starting normal system operation.

Recommendations

Use corrosion-inhibiting coolant compatible with copper and brass components, check for clearance in your case before purchase, and follow standard leak-test procedures after assembly. For optimal performance, pair the radiator with a high-quality 140 mm fan matched for static pressure and RPM appropriate to your noise and cooling needs.
