120 mm Copper Radiator for Custom Loops

The Alphacool NexXxos Monsta is a 120 mm radiator built for DIY liquid-cooling systems. Its core uses copper chambers, fins and channels with brass G1/4 threads and steel side panels. Six ports allow flexible loop routing. The black finish suits stealth-themed builds.

Clearance and Port Check Before Ordering

Verify that your case can accommodate a 160 x 124 x 86 mm radiator with a single 120 mm fan mount. Ensure you have six G1/4 fittings and enough tubing length to reach the port positions. The unit weighs 1 170 g, so confirm the mounting point can support that mass.

Suits Single-Fan Loops.

This radiator fits builders who need one dense 120 mm heat exchanger in a tight chassis. It does not suit loops that require multiple radiators in series or builds limited to thinner profiles under 80 mm core depth.

Questions about this item

What comes in the box with the Alphacool NexXxos Monsta 120mm radiator and what must be purchased separately?

The radiator itself is supplied with six G1/4 threads ready for fittings. You will need to buy G1/4 fittings, tubing, coolant, a 120mm fan and mounting screws separately.

Which version of the NexXxos Monsta should I choose for a single 120mm fan mount?

This model is the 120mm single-fan version measuring 160 x 124 x 86mm and weighing 1170g, designed for one 120mm fan.

What does the 80mm thickness mean for cooling performance inside a PC?

At 86mm overall depth including the 80mm core, the radiator holds more coolant and fin surface than slimmer units, giving higher heat capacity for a single 120mm fan.
