Alphacool Radiator ES HPE-60 Full Copper X-Flow 80mm Quad 5 Bar

Alphacool ES HPE-60 Full Copper X-Flow 80mm Quad 5 Bar is a compact, full-copper radiator intended for closed-loop and custom liquid cooling systems in PCs. The X-Flow core design channels coolant through a dense array of copper fins and tubes to maximize thermal transfer while keeping the unit small enough for cases that use 80mm fans. With four 80mm fan mounting positions and a 5 bar pressure rating, this radiator is suitable for high-flow loops and systems requiring robust, corrosion-resistant heat rejection.

Advantages

The full-copper construction ensures high thermal conductivity and long-term resistance to coolant-related degradation. The X-Flow architecture provides an even distribution of coolant across the core for consistent heat dissipation. A quad 80mm fan configuration offers flexible cooling options in tight installation spaces, and the 5 bar rating supports higher-pressure pump setups. The compact footprint simplifies integration into small form-factor builds or tight mounting locations.

Suitable for

• Custom PC water-cooling loops where space is limited
• System upgrades requiring compact radiators with 80mm fan mounts
• Replacement of older or damaged 80mm-based radiators
• High-flow cooling setups compatible with higher pump pressures

Key specifications

• Core material: full copper (tubes and fins)
• Flow design: X-Flow (cross-flow coolant distribution)
• Fan compatibility: four 80mm fans (quad configuration)
• Maximum operating pressure: 5 bar
• Mounting: standard 80mm fan mounting pattern for four positions
• Application: PC liquid cooling radiators for compact or small-form-factor builds

How to use

Install the radiator in the case or external loop section using the four 80mm fan mounting positions; ensure correct orientation for inlet and outlet ports to maintain efficient flow through the X-Flow core. Attach compatible 80mm fans to create push, pull, or push-pull configurations depending on available space and desired airflow. Connect tubing using appropriate fittings and clamps rated for the system pressure, then fill and bleed the loop according to standard liquid-cooling procedures. Verify there are no leaks and that the pump delivers stable flow before powering the full system.

Usage recommendations

Use corrosion-inhibiting coolant compatible with copper components and inspect fittings and hoses regularly. For best thermal performance in compact setups, combine the radiator with high-static-pressure 80mm fans and consider a push-pull arrangement if clearance allows. Monitor system temperatures after installation and avoid exceeding the specified maximum operating pressure.
