Alphacool NexXxoS Monsta 280 mm Radiator 14190

NexXxoS Monsta 280 mm Radiator

The Alphacool NexXxoS Monsta 280 mm radiator is a full-copper liquid-cooling heat exchanger built for custom loops. Its chambers, fins and channels are all copper, removing the brass tanks found on many competitors. Two 140 mm fan slots give ample airflow for high-wattage CPUs and GPUs. Enthusiasts who want a single radiator that scales across multiple builds will appreciate the consistent construction.

Replaces mixed-metal radiators

Swapping an aluminium-tank radiator for this full-copper design eliminates galvanic-corrosion risk and improves thermal transfer. The jump is worth it when you run high flow rates or plan to keep the loop filled for years without draining. Builders staying with an existing copper loop gain no material advantage, so the upgrade only makes sense if the current radiator uses dissimilar metals.

Fits dual 140 mm mounts

The unit slots into any case or bracket with 280 mm dual 140 mm mounting holes. Included hardware supplies M3 × 30 mm and M3 × 35 mm screws plus five plugs for unused ports. No proprietary brackets are required, freeing you to choose fans, tubing routes and reservoir placement independently. Ensure your chassis clears the radiator thickness before ordering.
