Jäähdytinlohko Alphacool NexXxoS Monsta

The Alphacool NexXxos Monsta radiator block is a full-copper heat exchanger designed for liquid cooling systems. Constructed with copper chambers and fins plus brass and steel components where applicable, this 324 × 144 × 86 mm black radiator is optimized for high-performance setups and high flow rates. Its flat chamber design reduces overall length for easier mounting, and the internal protective ledge prevents screw damage to the fins.

Advantages

All main parts of the NexXxos Monsta are made from copper, which improves thermal performance compared with radiators that use mixed materials. Separated chambers direct coolant flow for better circulation and higher flow rates. Multiple inlet/outlet positions and a 1/4" screw plug (on UT60 and Monsta models) simplify de-aeration, filling and vertical installation. The radiator supports 120 mm, 140 mm or 180 mm fan configurations and is available in 30 mm, 45 mm and 60 mm thicknesses, providing options for different cooling demands. M3 threaded mounting points and an internal screw-stop ledge increase mounting flexibility and reduce the risk of damage during assembly.

Suitable for

• High-performance PC liquid cooling loops
• Systems requiring high coolant flow rates
• Tight enclosures where flexible mounting positions are needed
• Setups using 120 mm, 140 mm or 180 mm fans

How to use

Install the NexXxos Monsta into your liquid cooling loop using the available inlet and outlet positions; select fittings and tubing that match the radiator ports. Mount fans and grills using standard M3 screws, taking advantage of the internal protective ledge to avoid fin damage. If present on your model, use the 1/4" screw plug for de-aeration and for filling when required. Ensure secure, leak-free connections and follow your cooling loop’s priming procedure before running the system at full load.

Recommendations

For optimal thermal performance, pair the NexXxos Monsta with medium-speed to slow-spinning fans to balance noise and cooling efficiency, and allow high flow rates through the separated chambers by minimizing sharp fitting angles.
