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.

Questions about this item

Does the radiator come with fans or do I need to buy 120 mm fans separately?

The box contains the radiator, four screw plugs and mounting hardware. Two 120 mm fans are not included and must be purchased separately.

How do I decide between the 45 mm thick X-Flow and a slimmer radiator for my loop?

The 45 mm thickness gives more fin surface for heat dissipation, but needs 45 mm of clearance plus fan depth. Choose it when space allows and you want maximum cooling capacity.

What does the 240 mm size mean for actual cooling performance in a custom loop?

A 240 mm radiator with two 120 mm fan slots handles typical CPU or GPU loads well; the full-copper construction and X-Flow design improve heat transfer at high flow rates.
