Alphacool NexXxoS XT45 Full Copper X-Flow 240mm Radiator

Radiator for Custom Loops

The Alphacool NexXxoS XT45 Full Copper X-Flow 240 mm radiator is built for enthusiasts assembling custom water-cooling systems. Its full-copper construction extends to the chambers, fins and channels for consistent thermal transfer. The X-Flow internal layout is designed to support high flow rates through the 240 mm core. It suits builders who want a single 240 mm heat exchanger without mixing metals in the loop.

Check Case Clearance and Port Layout

Verify that your chassis has a 240 mm mounting area with enough depth for the 45 mm thick core and any attached fans. Confirm the inlet and outlet port positions match your planned tubing runs so fittings clear surrounding components. Ensure the loop pump can deliver the flow rate the X-Flow design is engineered for. The radiator uses standard G1/4 threads, so check that your fittings match this thread type.

Included Hardware Simplifies Installation

The box supplies one radiator, four screw plugs and the required mounting hardware for a two-fan 120 mm configuration. The plugs seal unused ports so you can choose the flow direction that best fits your build. Mounting hardware lets you secure the unit to the case without sourcing separate screws. No coolant, tubing or fans are included, so budget for those separately.
