Radiator Alphacool NexXxoS XT45 1011660

Alphacool NexXxoS XT45 Full Copper X-Flow 120mm radiator (MPN 1011660, EAN 4250197142328) is a 45 mm thick cooling radiator designed for water-cooling systems. The NexXxoS XT45 uses a full-copper construction for the main parts and channels and an X-Flow internal layout that distributes coolant evenly across all channels to support high flow rates and efficient heat transfer.

Advantages

The full-copper chambers and channels provide improved thermal conductivity compared with typical mixed-metal designs. The X-Flow internal geometry equalizes flow across channels to maintain performance at higher flow rates. Multiple inlet/outlet positions on the chamber allow versatile fitting orientations and reduce the need for angled fittings. Standard M3 threaded mounting points and an internal protective ledge prevent damage from over‑inserted screws. Fin spacing and design enable good performance with low- and medium-speed fans, offering quieter operation and a wide choice of compatible fans.

Suitable for

• Custom PC water-cooling loops for CPU and GPU cooling
• High-flow cooling setups requiring low pressure drop
• Enthusiast and professional builds where copper construction is preferred
• Installations using standard 120 mm fans

How to use

Install the radiator in your water-cooling loop using standard 120 mm fan mounts and M3 screws. Choose the inlet/outlet positions on the chamber that give the most direct routing for your tubing to minimise angled fittings and maintain flow. Attach fans as required for your desired airflow; the fin spacing provides good results with low- and medium-speed fans. When fastening, the internal protective ledge reduces the risk of fin damage from over‑inserted screws, but tighten screws carefully to avoid strain on the threads.

Usage recommendations

Use corrosion‑safe coolant compatible with copper. Select fans that match your noise and airflow targets — the XT45 performs efficiently with slow to medium fan speeds. Check fittings and tubing orientation to preserve the X-Flow advantages and minimise pressure losses.
