## Long description

The Alphacool NexXxos ST30 radiator block is a prefilled expansion radiator for Alphacool CPU and GPU AIO liquid-cooling systems. Constructed mainly from copper for all coolant-facing parts, with brass ports for threaded strength, the NexXxos design uses a 16 FPI fin density and angled fin flaps to increase air turbulence and cooling efficiency while remaining effective with slower fans. The radiator is supplied with TPV tubing and matching quick-release fasteners and fittings for straightforward, low-evaporation connection to compatible Alphacool AIOs.
Advantages
All coolant-exposed components — end chambers, water channels and fins — are copper, while ports use brass for improved thread durability. The 16 FPI fin density balances airflow resistance and thermal transfer so the radiator performs well with lower-RPM fans. TPV tubing resists kinking, extreme temperatures and does not leach plasticizers, maintaining flexibility and appearance over time. Quick-release connectors are screw-lock safety couplings that limit fluid loss to one or two drops when disconnected and prevent accidental opening. TPV fittings include an integrated locking ring and deliver high tensile strength (over 15 kg).
Suitable for
Expanding Alphacool CPU AIO cooling loops with an additional radiator
Adding a radiator to an Alphacool GPU AIO or connecting a GPU cooler to a CPU AIO
Workstation and server setups requiring durable TPV tubing and reliable quick-disconnects

Weight (product data): 0.805–1.17 kg (manufacturing variance noted in product data)
How to use
Mount the NexXxos ST30 radiator at the chosen position inside your PC case using standard 120 mm fan/radiator mounting points. Connect the supplied TPV hoses to your Alphacool AIO using the matching quick-release fasteners: align male and female connectors, then screw them together until the safety lock engages. After connection, verify there are no leaks; only one or two drops may escape when opening a connector. No additional coolant topping is required for normal single-use connections, though repeated disconnection and reconnection may eventually require a small top-up.
Usage recommendations
Use with compatible Alphacool AIO systems and 120 mm fan layouts. Ensure quick-release connectors are fully screwed together to prevent accidental opening. For long-term reliability, install in systems where TPV tubing advantages (temperature tolerance, no plasticizer bleed) are beneficial, such as workstations and servers.
