Overview

This all-in-one liquid cooler pairs a 420mm radiator with three Noctua NF-A14 140mm PWM fans and a three-phase pump motor. It fits modern Intel and AMD sockets and includes an illuminated meter on the pump head for live system monitoring.

Design and Build

The cooler uses a 420mm aluminum radiator with copper cold plate and ABS pump housing. Three Noctua NF-A14 140mm PWM fans are pre-installed, each rated at 31.5 dB(A) maximum noise. The all-black color scheme covers radiator, fans, and tubing for a uniform look.

Performance and Use

A three-phase motor drives the pump for strong coolant flow while keeping acoustic output low. The included Noctua fans are optimized for static pressure across the thick radiator. The 45cm tube length allows flexible routing in full-tower and mid-tower cases.

Display and Lighting

An illuminated meter on the pump cover reports real-time CPU load, temperature, and fan speed at a glance. White LED lighting on the pump head adds subtle illumination without RGB complexity.

Compatibility and Contents

Mounting hardware covers Intel sockets 1150, 1151, 1155, 1156, 1200, 1700, 1851 and AMD AM4 and AM5. The package includes the radiator, pump unit, three 140mm fans, and required mounting brackets.
