Alphacool NexXxoS Monsta radiátorblokk

The Alphacool NexXxos Monsta radiator block is a full-copper heat exchanger designed for liquid cooling in high-performance computer systems. Constructed with copper fins, channels and chambers, the NexXxos Monsta offers increased thermal conductivity and an internal structure that directs coolant flow through separated chambers. Its flat chamber design reduces overall length while providing compatibility with 120 mm fans and a robust mounting range for tight enclosures.

Advantages

All main components of the NexXxos Monsta are made from copper, providing a material advantage in heat transfer compared with radiators that only use copper fins. Separated and flat chambers allow high flow rates and flexible mounting, while multiple fitting positions on inlet and outlet reduce the need for angled fittings and improve coolant flow. Standard M3 threaded fan mounting, an internal protective ledge to prevent fin damage from over-inserted screws, and a 1/4" screw plug for deaeration or filling (on supported models) add practical installation and maintenance benefits.

Suitable for

• High-performance desktop and workstation liquid-cooled PCs
• Systems requiring high coolant flow and efficient heat dissipation
• Installations with limited space where versatile mounting is needed

How to use

Mount the radiator in a suitable location inside the chassis using standard M3 screws and compatible fan(s). Connect inlet and outlet fittings to the loop using the preferred tubing and fittings; use the multiple fitting positions to minimize angled fittings and preserve flow. If present on your model, use the 1/4" screw plug for deaeration or to assist with filling when paired with a fill port. Ensure fans are oriented for the desired airflow and that the radiator is secured to avoid vibration.

Recommendations

Choose fan speeds according to the required cooling performance and noise level: the Monsta 80 mm thickness delivers higher performance at medium and high fan speeds compared with thinner radiators, while the NexXxos fin design provides good results even with slow- or medium-speed fans. Maintain the loop with clean coolant and periodic checks for air pockets to preserve thermal performance.
