Alphacool HPE-30 Full Copper 280mm wit radiator

The Alphacool HPE-30 Full Copper 280mm white radiator is a liquid-cooling heat exchanger engineered for custom PC water-cooling loops. Constructed entirely from copper, the 280 mm radiator accommodates a dual-fan configuration and offers high thermal conductivity to transfer heat away from CPU and GPU water blocks. Its white finish integrates with light-themed builds while the full-copper construction focuses on efficient heat dissipation and longevity in continuous cooling operation.

Advantages

Full-copper construction ensures superior thermal conductivity compared with mixed-metal designs, improving heat transfer efficiency. The 280 mm form factor supports two 140 mm or two 120 mm fans (depending on mounting design) for flexible fan configurations and effective airflow. A compact length makes it suitable for many mid-tower and compact cases where a balance between cooling capacity and space usage is required. The white coating offers aesthetic integration without compromising the underlying copper performance.

Suitable for

• Custom PC water-cooling loops for CPU cooling
• GPU water blocks and combined CPU/GPU cooling loops
• Mid-tower and compact cases with limited radiator mounting length
• Builds that require a white aesthetic while maintaining high thermal performance

Key specifications

• Material: full copper (tubes and fins)
• Length: 280 mm suitable for dual-fan mounting
• Finish: white coated exterior
• Mounting: standard radiator mounting pattern for radiator fans and fittings
• Intended medium: liquid cooling for PC components

How to use

Install the radiator into the case at an appropriate mounting location that supports a 280 mm radiator, secure it using compatible fan screws and attach fans according to desired push, pull, or push-pull configurations. Connect inlet and outlet ports to the rest of the custom loop using compatible fittings and tubing, ensuring correct hose routing to avoid sharp bends. Fill and bleed the loop according to standard liquid-cooling procedures, check for leaks, and run the system to confirm proper flow and temperature stabilization before extended use.

Recommendations

Use quality corrosion-inhibiting coolant compatible with copper components and regularly inspect fittings and tubing for tightness. Match fan airflow and static pressure to your chosen fan configuration for optimal performance, and allow sufficient clearance in the case for airflow and maintenance access.
