What customers say
Customers highly value the Alphacool NexXxoS XT45 360mm radiator for its robust performance and exceptional value in custom water cooling. Its all-copper construction is a major advantage, contributing to superior thermal conductivity and long-term durability. Users confirm excellent heat dissipation, effectively managing high-TDP components even under heavy loads. The 45mm thickness enhances cooling but requires careful case compatibility checks. While the solid copper build results in substantial weight, this is accepted as a fair trade for the quality delivered. Appreciated port flexibility aids loop design. Overall, this radiator is strongly recommended as a durable, high-performing workhorse for PC cooling enthusiasts.
Know before you buy
Copper is an excellent thermal conductor, which allows the radiator to transfer heat away from your coolant more efficiently than aluminum alternatives. This ensures your custom loop maintains lower temperatures even when your CPU or GPU is under heavy load.
The 45mm thickness provides a balance between high surface area for cooling and physical clearance. While it is thicker than standard 30mm radiators, it should fit in most mid-tower and full-tower cases that support 360mm radiators, though you should verify your case's top or front clearance to ensure it doesn't interfere with your motherboard or RAM.
With 12 available ports, you have significantly more flexibility when routing your tubing. This allows you to choose the most direct path for your loop, reducing the need for complex fittings and making it much easier to drain or bleed air from the system.
Yes, with a fin density of 16 FPI (fins per inch), this radiator is designed to perform well with a variety of 120mm fans. It is optimized to handle high-speed fans up to 3000 RPM, making it a great choice for high-performance builds that require aggressive cooling.
The X-Flow design directs the water flow in a way that optimizes circulation through the radiator channels. This reduces flow resistance and ensures more uniform heat dissipation across the entire surface area of the radiator.
Every NexXxoS XT45 unit is pressure tested up to 1.5 bar before leaving the factory. This rigorous testing ensures the structural integrity of the copper channels and steel housing, providing peace of mind for your custom water cooling loop.
