Alphacool 14193 Heatsink

The Alphacool NexXxos radiator series brings a full-copper construction and flexible mounting options to PC water cooling. Designed for use with 120 mm, 140 mm or 180 mm fans and available in 30 mm, 45 mm and 60 mm thicknesses, the NexXxos aims to provide an efficient heat exchanger for a wide range of cooling loops. Main chambers, fins and channels are made from copper to improve thermal performance and allow high flow rates through separated chambers and flat internal channels.

Advantages

Full-copper main parts increase thermal conductivity compared with mixed-material radiators. Separated internal chambers and flat chamber design direct coolant flow, supporting higher flow rates and better overall loop performance. Multiple inlet/outlet fitting positions (except on the ST30 model) reduce the need for angled fittings and increase installation flexibility. A 1/4" threaded plug on UT60 and NexXxos Monsta models enables easy de-aeration and vertical mounting or can be used for filling together with a Fillport. Standard M3 threaded mounting points and an internal protective ledge prevent damage from over-inserted screws. The fin profile is optimised to work well with low and medium fan speeds, allowing quieter operation without sacrificing heat dissipation.

Suitable for

• Custom PC water-cooling loops requiring high thermal performance
• Systems where flexible radiator mounting is needed or space is limited
• Builds prioritising quieter operation with low-to-medium fan speeds

Key specifications

• Material: copper (main chambers, fins and channels)
• Fan compatibility: 120 mm, 140 mm or 180 mm fans
• Available thicknesses: 30 mm, 45 mm, 60 mm
• Design features: separated chambers, flat internal chambers for reduced overall length
• Mounting: M3 threaded mounting points; internal protective ledge to prevent fin damage
• De-aeration / fill option: 1/4" threaded plug on UT60 and Monsta variants

How to use

Install the NexXxos radiator in the loop using the M3 mounting points and attach compatible fans (120/140/180 mm) according to your case layout. Choose the radiator thickness (30/45/60 mm) that fits your available space and cooling requirements. Use the multiple inlet/outlet positions to minimise angled fittings and keep tubing runs direct. For UT60 and Monsta models, open the 1/4" threaded plug to de-aerate when filling the loop or use the opening with a compatible Fillport for easier filling. Ensure fittings are tightened to the correct specification and verify clear tubing routing through the separated chambers to maintain high flow rates.

Recommendations

For quieter operation and efficient cooling, pair the NexXxos radiator with low-to-medium speed fans and plan tubing runs using the available inlet/outlet positions to avoid excessive bends and angled fittings. When installing in tight spaces, use the flat chamber orientation and the multiple fitting options to achieve a compact, high-flow configuration.
