Efficient cooling performance for custom water cooling. The Alphacool NexXxoS HPE-45 radiator is your ideal solution for custom water cooling. The high fin density of 16 FPI allows for maximum airflow through thin copper fins, ensuring very efficient heat transfer. The radiator is particularly large at 420 mm, making it suitable only for very large towers.

The simple design with a matte finish allows the radiator to be visually integrated into almost any build. Connection to the water cooling system is made via four G1/4-inch ports. An additional G1/4-inch port serves as a fill-drain port, making the filling and draining of your custom loops as easy as possible.
