## Summary description

The Alphacool NexXxoS XT45 heatsink features a copper and steel construction, ensuring excellent heat dissipation. With dimensions of 144 mm width, 606 mm depth, and 45 mm height, it fits various setups. Weighing 2.27 kg, it provides durability and stability. Ideal for high-performance cooling solutions.

## Long description

The Alphacool NexXxos XT45 heatsink is a full-copper design intended for water-cooling loops in computer systems. Combining copper chambers and fins with a sturdy construction, the XT45 is built for effective heat dissipation while remaining compatible with 140 mm fan configurations. With a thickness of 45 mm, compact mounting depth and M3 mounting threads, this radiator suits a wide range of cooling layouts.
Advantages
The NexXxos XT45 uses copper for its main parts including chambers and fins, which improves thermal conductivity compared with radiators that use mixed materials. Separated internal chambers direct coolant flow for high flow rates and consistent performance. Flat chamber design reduces overall length, increasing mounting flexibility. Standard M3 threads and an internal protective ledge prevent fin damage from over‑inserted screws, and the fin spacing is tuned to work well with low to medium speed fans, allowing quieter operation and broader fan compatibility.
Suitable for
Custom water‑cooling loops in desktop PCs
High‑performance cooling setups requiring 140 mm fans
Installations with limited mounting depth where a 45 mm thickness is preferred

How to use
Mount the NexXxos XT45 in your water‑cooling loop using M3 screws to attach fans and radiator brackets. Connect inlet and outlet fittings to the appropriate chamber openings and ensure tight, leak‑free connections. Use the supplied or compatible 1/4" screw plug if needed for de‑aeration or vertical installation. Fill and bleed the loop following standard water‑cooling procedures and confirm correct coolant flow before powering the system.
Usage recommendations
For optimal balance of noise and cooling performance, pair the XT45 with medium‑speed 140 mm fans and ensure the loop supports good flow rates. When installing in tight enclosures, take advantage of the flat chamber design and multiple fitting positions to minimise angled fittings and preserve flow efficiency.
