## Summary description

The Alphacool NexXxoS XT45 Radiator block is designed for efficient liquid cooling. Made from high-quality brass, copper, and steel, it features a sleek black finish. Dimensions: 81mm width, 286mm depth, and 45mm height. The package includes the radiator, screws, washers, and an Allen key for easy installation. Ideal for enhancing cooling performance in PC builds.

## Long description

The Alphacool NexXxos XT45 radiator block is a mid-thickness liquid-cooling heat exchanger designed for PC water-cooling loops. Constructed with copper chambers and fins, the XT45 provides a full-copper internal path and separated flow channels to guide coolant efficiently while allowing high flow rates. Its compact design (81 mm width × 286 mm depth × 45 mm height) and flat chamber profile improve mounting flexibility and make installation possible in tighter enclosures. The package includes the radiator, screws, washers and an Allen key; the unit is finished in black and uses standard M3 mounting threads.
Advantages
The full-copper internal construction (chambers, fins and channels) increases thermal performance compared with mixed-metal designs. Separated chambers promote directed flow and sustained high flow rates for improved loop efficiency. Flat chambers reduce overall length for more flexible mounting options, and an internal protective ledge prevents damage from over-inserted screws. Compatibility with 120/140/180 mm fan form factors and common thickness options (including 45 mm) gives broad versatility. A 1/4" threaded port supports de-aeration, filling or use with a Fillport for simplified maintenance.
Suitable for
Custom PC liquid-cooling loops requiring a 45 mm radiator
Compact or mid-size enclosures where reduced radiator length is needed
Systems where high coolant flow rates and reliable thermal transfer are important

How to use
Mount the radiator using the included screws and standard M3 holes, aligning fans and grills as needed for airflow direction. Connect the inlet and outlet to your loop using appropriate fittings and tubing. Use the 1/4" threaded port for de-aeration or to attach a Fillport when filling or bleeding the loop. Ensure connections are tightened to manufacturer torque recommendations and perform a leak test before powering the system.
Usage recommendations
For balanced performance and low noise, pair the XT45 with medium-speed or low-speed PWM fans; regular bleeding via the 1/4" port improves initial filling and reduces trapped air. Check compatibility with your case and fan configuration before installation and follow standard water-cooling safety and maintenance practices.
