Radiatorblok Watercool 24101 – messing/koper/rvs, 278×120×30 mm, zwart

Watercool 24101 radiator block is a compact radiator designed for custom PC liquid-cooling loops. Constructed from brass, copper and stainless steel with a black finish, it measures 278×120×30 mm and is intended for dissipation of heat from liquid cooling systems. The radiator features a 30 mm thickness variant from the HEATKILLER RAD series, combining compact dimensions with attention to material quality and manufacturing standards.

Advantages

The combination of brass antechamber, copper cooling fins and stainless steel side panels delivers corrosion-resistant flow paths and efficient thermal transfer. Finished and assembled under quality control in Germany, the radiator offers consistent manufacturing tolerances and a refined appearance. Its slim 120 mm width and 30 mm thickness make it suitable for installations where space is limited while still maintaining effective cooling across a wide fan speed range.

Suitable for

• Custom water-cooling loops in desktop PCs
• Cooling of CPU and GPU blocks in single- or multi-radiator configurations
• Compact or slim chassis where radiator depth and width are constrained

Key specifications

• Materials: brass antechamber, copper cooling fins and channels, stainless steel or steel side panels
• Finish: black coated/brushed exterior
• External dimensions: 278 mm (width) × 120 mm (depth) × 30 mm (height)
• Thickness: 30 mm (Small RAD series)
• Threading interface: two G1/4" threaded ports for integration into cooling circuits
• Designed for push/pull configurations and efficient performance at low to high fan speeds

How to use

Install the radiator into the loop using the two G1/4" threaded ports and appropriate fittings (fittings not included). Mount fans or arrange push/pull configurations according to chassis space and desired airflow. Ensure secure sealing of fittings, follow manufacturer guidance for torque on threaded connections, and fill, bleed and test the cooling loop for leaks before normal operation. Position the radiator to allow unobstructed airflow through the fin stack and to simplify tube routing in the chassis.

Recommendations

Use corrosion-inhibited coolant compatible with copper and brass to prolong service life. For best performance in compact builds, pair the 30 mm radiator with high-static-pressure fans and verify adequate case ventilation. Periodic inspection and cleaning of the fin area will help maintain thermal performance.
