Radiator Magicool 120 G2 Slim Radiator Brass Copper 4 Fans

The Magicool 120 G2 Slim Radiator Brass Copper 4 Fans is a compact PC water-cooling radiator designed for efficient heat dissipation in space-constrained builds. Measuring 152 mm wide, 120 mm deep and 27 mm high, its brass and copper construction combines mechanical strength with high thermal conductivity. The radiator features copper fins optimized for operation with low-noise fans and parallel coolant channels that reduce liquid resistance for stable flow and improved cooling efficiency. Mounting flexibility is provided by integrated M3 threads on both sides for fan attachment and two G1/4" threaded ports on the top chamber for standard fittings.

Advantages

The slim profile allows installation in tight enclosures and compact PC cases while maintaining effective heat transfer thanks to copper fins and brass end tanks. Parallel coolant channels minimize flow resistance and help maintain pump efficiency in small-loop systems. Compatibility with standard G1/4" fittings and multiple M3 fan-mount points simplifies system integration and component upgrades. The radiator is engineered for quiet operation when paired with low-noise fans, supporting balanced thermal performance and acoustic control.

Suitable for

• Compact or small-form-factor PC builds where space for a radiator is limited
• Custom liquid-cooling loops requiring a slim 120 mm radiator
• Systems prioritizing low noise with performance-oriented cooling
• Upgrading existing water-cooling loops with a reliable, corrosion-resistant radiator

Key specifications

• Dimensions: 152 mm (width) × 120 mm (depth) × 27 mm (height)
• Material: brass end tanks and copper fins/heat-exchange surfaces
• Cooling configuration: designed for 4 fans (slim-profile mounting)
• Flow design: parallel coolant channels for reduced liquid resistance
• Threaded ports: two G1/4" ports located on the top chamber for fittings
• Fan mounting: integrated M3 threads on both sides for flexible fan attachment

How to use

Install the radiator in the case where space and airflow requirements are met, using the M3 mounting points to secure compatible slim fans. Connect the cooling loop using standard G1/4" fittings to the top-chamber ports and ensure tubing is routed without sharp bends to preserve flow. Fill and bleed the loop according to common liquid-cooling procedures, verify there are no leaks, and run the pump at the recommended operating speed to stabilize flow through the parallel channels. Monitor temperatures and fan speeds during initial operation to confirm expected thermal performance.

Usage recommendations

For optimal results, pair the radiator with low-noise slim fans to take advantage of the copper fins’ design. Use corrosion-inhibited coolant compatible with brass and copper components, and perform periodic checks for dust buildup in the fins to maintain airflow and thermal efficiency.
