Product information

Description

The Alphacool NexXxoS XT45 200 mm radiator is a high-performance liquid-cooling radiator constructed primarily from pure copper. End chambers, water channels and cooling fins are all made of copper to provide effective heat transfer. With a cooling surface of approximately 20 x 20 cm and a compact profile, the radiator is suitable for demanding CPU and GPU cooling setups where efficient thermal management is required.

Advantages

Using copper components increases thermal conductivity compared with aluminium, improving heat transfer from coolant to fins. The radiator uses a medium fin density (11 FPI) to allow good airflow even at low static pressure, while small serrations on each fin guide airflow and increase effective surface area to enhance cooling efficiency and reduce noise. The design supports both active and passive operation by mounting fans to a removable frame.

Suitable for

Custom PC liquid-cooling loops for CPUs
Liquid cooling for graphics cards (GPUs)
High-performance or compact builds requiring a 200 mm radiator

Key specifications

Material: copper (end chambers, water channels, cooling fins)
Fan diameter supported: 200 mm (mounting frame accepts 154 mm or 165 mm hole spacing)
Cooling surface area: approximately 20 x 20 cm
Fin density: 11 FPI with serrated fins for improved airflow and surface area
Fluid connections: four G1/4" ports for inlet/outlet and one additional G1/4" port on the rear for filling, sensor or drain
Colour: black
Dimensions (approx.): width 199 mm, depth 238 mm, height 48 mm
Weight: 1.04 kg

How to use

Install the radiator in your PC case or external mount, attach a compatible 200 mm fan to the supplied mounting frame (using either 154 mm or 165 mm hole spacing) or remove the frame for passive airflow. Connect the cooling loop using G1/4" fittings to the inlet and outlet ports; use the rear G1/4" port for filling, a temperature sensor or draining as needed. Ensure secure mounting and leak testing before filling the loop and powering the system.

Usage recommendations

For optimal results, pair the radiator with fans that match your airflow and noise targets—use lower static-pressure large-diameter fans with the 11 FPI fin density to achieve efficient cooling at moderate RPMs. Perform a full leak test after installation and allow time for air to purge from the loop to ensure consistent performance.
