Dissipatore Alphacool 14243

The Alphacool 14243 heatsink is part of the new-generation NexXxoS series designed for watercooling systems. Constructed primarily from copper components and finished in black, this 120mm-series radiator variant measures 144 mm × 477 mm × 30 mm and is intended to provide reliable heat dissipation for PC cooling loops. The NexXxoS X-Flow design promotes uniform flow through all channels, while three 1/4" threaded ports on each chamber increase installation flexibility.

Advantages

This heatsink combines full-copper main elements with an X-Flow internal layout built for high flow rates, offering improved thermal transfer and reduced flow restriction compared with conventional radiators. Standard M3 mounting threads simplify fan and faceplate installation. An internal protective edge prevents screws from contacting the fins, and fin spacing is optimised for effective performance with low to medium fan speeds.

Suitable for

• Custom watercooling loops in desktop PCs
• High-flow cooling configurations requiring minimal flow restriction
• Systems where low to medium fan noise is desired

How to use

Integrate the Alphacool 14243 into a closed-loop watercooling system by connecting inlet and outlet fittings to the 1/4" threaded ports. Choose port locations (top, bottom, front or back) according to your case layout to minimise the number of angled fittings and preserve flow. Secure fans and faceplates using M3 screws; the internal protective edge prevents screw over-insertion into the fin area. Ensure hoses and fittings are tightened to the correct torque to avoid leaks and run a leak test before full operation.

Recommendations

For balanced cooling and low noise, pair this 30 mm thick radiator with low- to medium-speed 120 mm fans and ensure adequate case airflow. When configuring high-flow loops, use straight fittings where possible to retain the X-Flow design benefits.
