Radiator Coolgate G2 120mm, 10 FPI, model CG120G2

The Coolgate G2 120mm radiator (model CG120G2) is a compact liquid-cooling heat exchanger designed for PC custom water-cooling loops. With a single 120 mm fan mounting footprint and a 10 FPI (fins per inch) fin density, this radiator is intended to provide effective heat dissipation in small to mid-size systems where space is limited or a single-radiator configuration is preferred. The radiator is constructed to integrate into custom cooling loops, offering standard 120 mm mounting compatibility and a balance between airflow resistance and thermal transfer suitable for many CPU and GPU cooling applications.

Advantages

The 10 FPI fin density offers a balance of thermal transfer and airflow, allowing common 120 mm fans to provide efficient cooling without excessive fan speed. Its compact single-fan size is suitable for builds with limited radiator mounting space and for users seeking a simple addition to an existing loop. The radiator's standard 120 mm mounting pattern ensures compatibility with a wide range of fans and brackets used in mainstream and compact PC cases.

Suitable for

• Custom PC water-cooling loops requiring a single 120 mm radiator
• Small form-factor and mid-tower systems with limited radiator space
• Upgrades where a compact radiator is needed for additional cooling capacity
• Cooling single components such as CPU-only or GPU-only loops in compact builds

Key specifications

• Form factor: Single 120 mm fan mount
• Fin density: 10 FPI (fins per inch)
• Intended use: Liquid-cooling radiator for PC loops
• Compatibility: Designed for standard 120 mm fans and mounts
• Application: Suitable for small to mid-size systems and compact cooling setups

How to use

Install the radiator into a compatible 120 mm mounting location in your PC case or custom mounting bracket. Connect inlet and outlet fittings to the radiator ports and ensure secure, leak-free connections with appropriate tubing and clamps or compression fittings. Mount a 120 mm fan to the radiator to direct airflow through the fins; choose orientation (push or pull) based on case airflow and space constraints. Integrate the radiator into your loop with a pump and reservoir, fill and bleed the system according to standard liquid-cooling procedures, and verify temperatures and leak-free operation before prolonged use.

Usage recommendations

For best results, use a fan with adequate static pressure to move air through the 10 FPI fin array, and check clearance and mounting points in your case before purchase. Regularly inspect tubing and fittings for seals and perform maintenance such as coolant replacement and fin cleaning to maintain thermal performance.
