Radiator MagiCool Magicool 120 G2 Slim — Brass/Copper, 152×120×27 mm, 4-fan support

The MagiCool Magicool 120 G2 Slim radiator is a compact brass-and-copper heat exchanger measuring 152×120×27 mm designed for 120 mm fan configurations. Built for small-form-factor liquid cooling loops and compact custom builds, this radiator uses copper fins and parallel coolant channels to maximize heat transfer while minimizing liquid resistance. The radiator accommodates up to four fans and offers threaded mounting points on both sides for flexible fan placement, while the top chamber features two common threaded ports for easy connection to fittings and barbs.

Advantages

The MagiCool Magicool 120 G2 Slim combines a brass frame with copper fins to deliver efficient thermal conductivity in a compact footprint. Its parallel channel design reduces flow resistance, enabling better pump performance in tight loops. Integrated threaded fan mounts on both sides allow multiple fan configurations and help balance airflow and noise. The top chamber ports accept standard threaded fittings for straightforward plumbing and maintenance.

Suitable for

• Small-form-factor PC liquid cooling loops
• Compact CPU or GPU cooling solutions
• Custom water-cooling builds with space constraints
• Silent fan configurations requiring optimized fin geometry

Key specifications

• Material: brass frame with copper fins and channels
• External dimensions: 152 × 120 × 27 mm
• Fan compatibility: designed for 120 mm fans; supports up to four fans
• Channel design: parallel coolant channels to reduce flow resistance
• Mounting: M3-threaded mounting points on both sides for fan installation
• Ports: two standard threaded ports on the top chamber for fittings/barbs
• Use case: suitable for compact radiators in PC water-cooling loops

How to use

Install the radiator in your loop according to available space and airflow direction, choosing fan placement that balances static pressure and noise. Secure 120 mm fans to the radiator using the provided M3 threaded points on either side, and connect tubing to the top-chamber threaded ports using appropriate fittings or barbs. Ensure the loop is correctly bled of air and that the pump provides sufficient flow through the parallel channels prior to full operation.

Usage recommendations

For optimal results, pair the radiator with slim or low-profile 120 mm fans in confined enclosures, and use a pump capable of maintaining steady flow through parallel channels. Regularly inspect fittings and tubing for leaks and flush the loop periodically to prevent particulate buildup in copper fins and channels.
