Overview

This all-in-one liquid cooler uses a 420mm radiator and three 140mm fans to handle high-end CPU thermal loads. It fits Intel LGA1700, LGA1851, AMD AM4, and AM5 platforms.

Cooling Performance

The 420mm radiator provides a large surface area for heat dissipation. Three 140mm PWM fans deliver adjustable airflow to keep overclocked CPUs stable under sustained workloads.

VRM Cooling Design

A dedicated fan integrated into the pump block directs air toward motherboard voltage regulators. This active cooling improves power delivery efficiency during heavy compute tasks.

Installation and Compatibility

Fans come pre-mounted on the radiator to simplify the build process. The mounting kit covers Intel LGA1700, LGA1851 and AMD AM4, AM5 sockets. Tubing measures 500mm for reach in full-tower chassis.

Build Details

The unit uses aluminum radiator fins with a copper cold plate. All components including fan frames, rotors, and radiator housing are black. Fans connect via standard 4-pin PWM headers for motherboard control.
