Coldplate Alphacool 13893 computerkølesystemkomponent

The Alphacool Apex 1 (AM5) coldplate is a precision-machined component designed to integrate into high-end custom water cooling systems. Machined from solid copper with a brass connection section and an aluminum cover, the coldplate delivers targeted liquid delivery to the CPU hotspot using Alphacool's cross-slot flow geometry and the 3D Jetplate 2.0. A pre-chamber before the Jetplate evens flow and increases pressure for consistent heat transfer. The top cover includes cutouts for uniform aRGB illumination and an additional diffused light element oriented toward the RAM area. The coldplate is sized to cover the CPU socket and mounting holes for a seamless appearance while installing with a motherboard-backplate screw system.

Advantages

The unit combines a solid-copper coldplate and CNC-machined brass connection for durable thermal contact and corrosion-resistant fittings. The 3D Jetplate 2.0 and cross-slot technology increase local water pressure and distribute coolant evenly across the coldplate fins, improving heat extraction from the CPU hotspot. The nearly enclosed aluminum cover provides a finished look and integrates aRGB lighting without affecting coolant flow. The design maintains straightforward installation via top-mounted cooler placement and a screw-secured backplate.

Suitable for

• Custom liquid-cooled AMD AM5 PC builds
• High-performance desktops requiring targeted CPU cooling
• Systems where aRGB lighting integration is desired

Key specifications

• Product type: Coldplate (CPU water block)
• Supported socket: AMD Socket AM5
• Materials: Copper coldplate, brass connection section, aluminum cover, acrylic/top transparent elements
• Fittings: 1/4" (standard G1/4" compatible)
• Max recommended pressure: 0.8 bar (design reference)
• Finish: Transparent/acrylic lighting elements, aRGB compatible

How to use

Position the coldplate over the CPU area on the motherboard so that the coldplate covers the socket and mounting holes. Secure the assembly by fastening the backplate from underneath the motherboard with the supplied screws. Connect inlet and outlet tubing to the brass 1/4" fittings and verify tight, leak-free connections. Integrate the aRGB wiring to the system controller according to the motherboard or controller manual. Fill the loop with compatible coolant, purge air, and run the pump to verify flow and cooling performance.

Recommendations

Use corrosion-inhibiting, PC-compatible coolant and follow the system manufacturer's guidance for filling and leak testing. Ensure fittings are properly tightened but avoid over-torquing brass components. Periodically inspect the loop for leaks and coolant condition to maintain reliable thermal performance.
