Overview

A 420mm all-in-one liquid cooler with three 140mm PWM fans, addressable RGB lighting, and a serviceable refill port. Compatible with current Intel and AMD desktop sockets.

Pump and Radiator Design

The 3-chamber pump isolates the motor from the coolant path to reduce vibration and noise. Speed ranges from 1,700 to 3,500 RPM. The 420mm aluminum radiator measures 27mm thick, or 52mm with fans installed, and uses 400mm flexible tubes.

Fan Performance

Three Silent Wing 4 140mm PWM fans are pre-installed. Each fan uses a 4-pin connector for speed control. The radiator corners are shaped to improve airflow and lower acoustic output.

Lighting and Aesthetics

The pump housing features digitally addressable RGB LEDs connected through a standard 3-pin 5V digital header. All visible surfaces, including the radiator, fan frames, and rotors, are finished in black.

Installation and Maintenance

A top-mounted refill port allows coolant top-ups without removing the unit. The package includes a coolant bottle and mounting hardware for all listed Intel and AMD sockets. The cold plate uses a nickel-plated copper base for thermal conductivity.
