## Summary description

The Alphacool NexXxoS XT45 heatsink features a sleek black design with dimensions of 186 mm width, 144 mm depth, and 46 mm height. It is engineered for efficient heat dissipation, making it ideal for high-performance cooling systems. Its robust construction ensures durability and reliability, while the optimized fin structure enhances airflow, providing superior thermal management for your PC components.

## Long description

The Alphacool NexXxos XT45 heatsink is a full-copper construction radiator designed for PC water-cooling loops. With a black finish and dimensions of 186 x 144 x 46 mm, it supports both 120 mm and 140 mm fans and is offered in a 45 mm thickness optimized for balanced airflow and cooling performance. The radiator features separated flat copper chambers to direct coolant flow, M3 mounting threads, and 1/4" connection threads.
Advantages
The NexXxos XT45 uses predominantly copper for internal parts including chambers, fins and channels, which improves thermal transfer compared with radiators that use mixed materials. Flat chambers reduce overall length and increase mounting flexibility, while separated chambers ensure a clear coolant path allowing high flow rates. The design includes an internal protective ledge to prevent fan screws from damaging the fins, and a fin structure optimized to perform well with low- and medium-speed fans.
Suitable for
Custom PC water-cooling loops for CPUs and GPUs
Compact builds requiring flexible radiator mounting
Systems prioritizing quiet operation with low- to medium-speed fans

How to use
Install the NexXxos XT45 into your loop using the M3 mounting points and choose 120 mm or 140 mm fans according to your case layout and desired airflow. Connect tubing to the 1/4" threaded ports; the radiator offers multiple inlet/outlet positions to reduce angled fittings and improve flow. For models with a 1/4" screw plug, use this port for de-aeration or filling when needed. Tighten fittings and screws carefully—internal protective ledges reduce the risk of fin damage from overlong screws.
Usage recommendations
Use low- to medium-speed fans for an optimal balance of cooling performance and noise. When installing in tight enclosures, take advantage of the multiple inlet/outlet positions to minimize angled fittings and maintain high flow rates. If filling or bleeding the loop, use the provided threaded opening and compatible fill ports for safe, easy service.
