## Summary description

The Alphacool NexXxoS ST30 heatsink features a robust construction with brass, copper, and steel materials. Measuring 125 mm in width, 278 mm in depth, and 30 mm in height, it provides excellent thermal performance for your cooling needs. The sleek black finish adds a modern touch to your setup, making it an ideal choice for efficient heat dissipation in high-performance systems.

## Long description

The Alphacool NexXxos ST30 heatsink is a compact water-cooling radiator designed for PC liquid-cooling loops. Constructed with brass, copper and steel components and finished in black, the ST30 offers a slim 30 mm thickness in a 125 x 278 x 30 mm form factor and is intended to provide efficient heat dissipation for high-performance systems.
Advantages
The NexXxos ST30 uses a full-copper construction for core parts, including fins, channels and chambers where applicable, improving thermal transfer compared with radiators that use mixed materials. Separated flat chambers guide coolant flow for consistent throughput and the internal protective ledge prevents damage from over-inserted screws. Compatibility with both 120 mm and 140 mm fan mounting and standard M3 threads simplifies installation and broadens fan choices. A 1/4" screw plug on compatible NexXxos models enables easy de-aeration and vertical mounting options.
Suitable for
Compact PC liquid-cooling loops where a 30 mm thick radiator is required
Systems requiring a black, low-profile radiator for tight enclosures
Builds that use 120 mm or 140 mm fans with standard M3 mounting

How to use
Install the NexXxos ST30 into your closed-loop liquid-cooling circuit, mounting fans according to the desired push or pull configuration using the standard M3 threads. Route inlet and outlet fittings to match your loop layout, taking advantage of the chamber fitting positions to minimize angled fittings and improve flow. If present on your model, use the 1/4" screw plug for de-aeration or filling in combination with a fill port. Observe standard precautions when tightening screws to avoid excessive force even though the internal ledge offers protection.
Usage recommendations
Use low- to medium-speed 120 mm or 140 mm fans for balanced noise and cooling performance. For best results, ensure good case airflow and avoid overly long or restrictive tubing runs that could reduce flow rate through the radiator.
