Full-copper X-Flow 140mm radiator

The Alphacool NexXxoS XT45 is a full-copper water-cooling radiator built for custom-loop builders who want every component in the coolant path made from copper. Its 45 mm thickness and X-Flow internal structure are designed to handle high flow rates without restricting the loop. The package includes the radiator, two screw plugs and mounting hardware. Condition is new.

Practical limits of 45 mm thickness

A 45 mm thick radiator demands more case clearance than slimmer models and works best with fans that deliver strong static pressure to push air through the dense fin stack. Builders must verify that their chassis can accommodate the extra depth and that the chosen fans can overcome the added airflow resistance. Loop planners should also confirm that the pump can sustain the flow rates the X-Flow design is built for.

Copper chambers decide thermal performance

Unlike radiators that only use copper for fins and channels, this model forms the chambers from copper as well, removing a thermal bottleneck at the fluid entry and exit points. That construction detail is the single specification that determines whether the radiator can deliver the heat-exchange efficiency the builder expects. If the loop design relies on maximum conductivity at every joint, the full-copper chambers make this the correct part.

Questions about this item

How do I pick the right size from the XT45 line?

The XT45 140mm radiator is built for 140mm fan mounts and has a 45mm core thickness; verify your case clearance before ordering.

What does the 45mm thickness deliver inside a loop?

A 45mm thick full-copper core with X-Flow chambers increases coolant volume and surface area, lowering coolant temperatures at high flow rates.

What fitting standard does the X-Flow design use and what flow ceiling does it hit?

Standard G1/4 threads accept any common fitting; the bevelled X-Flow chambers are engineered for unrestricted high-flow operation.
