A full-copper X-flow radiator with 45 mm thickness and 120 mm fan spacing for high-flow liquid cooling loops

  • TypeRadiator

Size 120mm

  • Full copper construction improves thermal transfer across every component
  • X-Flow design supports high coolant flow rates for efficient cooling
  • 45 mm thickness increases surface area for better heat dissipation
  • 120 mm fan compatibility fits standard water-cooling layouts
  • Includes mounting hardware and four screw plugs for straightforward installation

Full-Copper 45mm Radiator

The Alphacool NexXxoS XT45 is a 120mm water-cooling radiator built entirely from copper, including its chambers, fins and channels. It uses an X-Flow internal structure designed for high flow rates through the heat exchanger. The package includes the radiator, four screw plugs and mounting hardware.

Custom Loop Builders Seeking Maximum Thermal

This radiator suits enthusiasts assembling a custom liquid-cooling loop who want the heat-transfer benefits of an all-copper construction. It is not intended for builders who need a radiator with integrated fans or a pump, nor for those looking for an all-in-one closed-loop cooler.

45mm Thickness and X-Flow Port Layout

The 45mm core depth and X-Flow port arrangement determine whether this radiator fits the available case clearance and matches the planned tubing runs. Verify both dimensions against your chassis and loop design before purchase.

Questions about this item

What port standard does the Alphacool NexXxoS XT45 use, and what flow rate does it support?

It uses standard G1/4 ports and the X-Flow design is built for high flow rates through full-copper chambers and channels.

What mounting hardware and clearance does the 120mm radiator need?

The 45mm thick radiator includes mounting hardware and screw plugs; it fits 120mm fan locations but requires space for its 45mm depth.

How is the radiator installed and which step is often missed?

Mount the radiator with the included hardware, attach fans, connect G1/4 fittings, then fit the four screw plugs into the unused ports before filling the loop.
