Prefilled Copper Radiator for AIO Expansion

The Alphacool NexXxoS ST30 is a 240mm prefilled radiator designed to increase the cooling capacity of an existing Alphacool AIO system. It uses solid copper for the end chambers, water channels and fins, with brass G1/4 threads. The unit arrives ready to connect via quick-release fasteners.

Builders Expanding an Alphacool AIO Loop

This radiator suits owners of a compatible Alphacool CPU or GPU AIO who want extra thermal headroom without building a custom loop. It will not help buyers who need a standalone cooler, a different radiator length, or a unit that works with non-Alphacool quick-connect fittings.

Simple Mount-and-Connect Installation

Mount the 278 x 124 x 30 mm radiator in the case, then attach the supplied TPV hoses to the matching AIO quick-release ports. The 16 FPI fin density works well with low-RPM fans. The only common issue is discovering the existing AIO lacks the required quick-release connectors after the radiator is already mounted.

Questions about this item

Do I need an existing Alphacool AIO with quick-release fittings to use this prefilled 240 mm copper radiator?

Yes, the radiator is designed to expand an Alphacool CPU or GPU AIO by connecting its quick-release fasteners to the corresponding AIO system.

Will the 16 FPI fin density work well with the low-speed fans I already have installed?

The 16 fins per inch and turbulence flaps are engineered for good performance with slow-rotating fans, avoiding the higher airflow resistance of denser fin stacks.

How can I verify the TPV tubing is handling temperatures correctly after installation?

TPV hoses are rated for continuous operation from -50 °C to +155 °C, so normal loop temperatures well within that range confirm the tubing is performing as specified.
