Alphacool NexXxoS ST30 1011657 Full Copper 360mm radiator 400x124x30mm 12ch 16FPI X-Flow black

Alphacool NexXxoS ST30 Full Copper 240mm Radiator V.2 (4250197142298)

The Alphacool NexXxoS ST30 (1011657) is a high-performance 240mm radiator designed for custom liquid cooling loops where space efficiency and thermal capacity are critical. As part of the V.2 series, this radiator features a revised internal structure and a sleek modern aesthetic. Unlike many competitors that use aluminum fins, the NexXxoS ST30 utilizes full copper for the cooling fins, channels, and chambers, providing superior heat conductivity and preventing galvanic corrosion within the loop. With a slim 30mm profile, it is ideal for compact builds or installations in areas with limited clearance. The ST30 V.2 also introduces flush-mounted screw plugs that sit level with the radiator surface, preventing interference with the case frame. Its fin density is optimized for low-to-medium fan speeds, allowing for near-silent operation while still providing the thermal dissipation required for high-end CPUs and GPUs.

Key Features

* Full Copper Construction: Every part that comes into contact with the coolant is made of high-quality copper, ensuring maximum heat transfer and eliminating the risk of mixed-metal corrosion in the cooling system.

* Versatile Port Configuration: Features a total of five G1/4" ports, including a specialized port on the end chamber that can be used for air bleeding, filling, or as a convenient drain point.

* Flush-Mount Screw Plugs: The V.2 design utilizes patented screw plugs that sit flush with the radiator housing, ensuring a clean look and preventing mounting issues in tight PC chassis.

* Optimized for Silence: The 15 FPI fin density is specifically tuned to work effectively with low-RPM fans, delivering excellent cooling performance without the noise associated with high-density radiators.

* Protective Internal Buffers: Includes internal protection plates beneath the mounting holes to prevent long screws from piercing the copper cooling channels during installation.
