Radiator Alphacool R27-S360 360 mm copper fins, 360mm slim water-cooling radiator

Alphacool R27-S360 is a 360 mm slim water-cooling radiator with copper fins designed for PC liquid cooling loops. The 360 mm length accommodates triple-fan configurations while the copper fin construction offers effective thermal transfer and durability. Intended for custom loops, this radiator balances cooling surface area with a low profile to fit cases with limited radiator clearance and to support sustained heat dissipation from high-performance CPUs and GPUs.

Advantages

The copper fin design increases thermal conductivity compared with standard aluminium fin radiators, enabling improved heat transfer from coolant to airflow. The slim 27 mm thickness reduces case space requirements while still providing a broad surface area for heat exchange. Compatibility with 120 mm fans in a triple configuration allows flexible fan choices for different noise and airflow priorities. Corrosion-resistant materials and soldered joints ensure long-term reliability in sealed liquid cooling systems.

Suitable for

• Custom PC water-cooling loops for CPU cooling
• GPU cooling in high-performance gaming or workstation builds
• Small to mid-tower cases where a slim 360 mm radiator is required
• Multi-fan configurations (three 120 mm fans) for varied airflow/noise trade-offs

Key specifications

• Radiator length: 360 mm (triple-fan mount)
• Radiator thickness: slim profile (~27 mm fin assembly)
• Fin material: copper
• Core construction: multiple water channels with soldered joints for durability
• Fan compatibility: three 120 mm fans, standard mounting hole pattern
• Intended use: external loop component for liquid cooling systems

How to use

Install the radiator in a compatible case location that supports a 360 mm triple-fan mount, ensuring adequate clearance for the slim profile. Mount three 120 mm fans to the radiator using the standard hole pattern and orient airflow to match the case cooling strategy (intake or exhaust). Connect the radiator to the loop using appropriate fittings and tubing, then fill and bleed the cooling loop according to the liquid cooling system instructions. Verify there are no leaks and monitor temperatures during an initial testing period to confirm correct flow and heat dissipation.

Recommendations

Use corrosion-inhibiting coolant and compatible fittings to preserve the copper fins and internal channels. Select fan speeds and airflow configuration based on the desired balance between acoustic noise and cooling performance. Periodically inspect the radiator for dust accumulation and clean fins with compressed air to maintain peak thermal efficiency.
