## Summary description

The Alphacool NexXxoS XT45 heatsink features a copper and steel construction, ensuring excellent thermal conductivity. With dimensions of 124 mm width, 280 mm depth, and 46 mm height, it is designed for efficient heat dissipation in high-performance cooling systems. Its robust design and compatibility with various setups make it a reliable choice for enthusiasts looking to enhance their cooling solutions.

## Long description

The Alphacool NexXxoS XT45 heatsink is a passive cooling component constructed from copper and steel to provide efficient thermal transfer in high-performance cooling systems. With overall dimensions of 124 mm width, 280 mm depth and 46 mm height and a weight of 1.199 kg, the XT45 is designed to be integrated into liquid-cooling radiators or custom cooling assemblies where a robust, conductive heatsink is required. The product does not include an active fan and is intended to complement other cooling elements rather than act as a standalone processor cooler.
Advantages
Constructed from copper and steel, the NexXxoS XT45 delivers good thermal conductivity and mechanical strength for demanding installations. Its compact footprint combined with a 46 mm profile enables installation in tight spaces while still providing a substantial thermal mass. The passive design reduces moving parts and noise while offering dependable heat dissipation when paired with appropriate coolant flow or forced-air solutions.
Suitable for
 Integration into custom liquid-cooling radiators and heat-exchange assemblies
 Systems requiring additional thermal mass without introducing fans
 Environments where space-constrained cooling components are necessary
Key specifications
 Material: copper and steel construction for thermal conductivity and strength
 Dimensions (W × D × H): 124 mm × 280 mm × 46 mm
 Weight: 1.199 kg
 Fan diameter: 0 mm (passive component, no integrated fan)
 Mounting and compatibility: designed for integration into cooling assemblies rather than direct CPU socket mounting
How to use
Install the NexXxoS XT45 as part of a cooling assembly following the mechanical requirements of your custom loop or radiator design. Secure the heatsink to the intended bracket or housing using appropriate fasteners and ensure good thermal contact with the mating surface where heat transfer is required. If used within a liquid-cooling radiator, confirm coolant flow and pump capacity are sufficient to transfer heat away from the heatsink; if paired with fans, position them to provide directed airflow across the assembly for improved performance.
Usage recommendations
For optimal results, combine the XT45 with a high-flow pump and adequate radiator capacity in closed-loop systems, and verify mounting points and clearances before final assembly. Regularly inspect mechanical fastenings and thermal interfaces to maintain consistent heat transfer over time.
