Overview

A 420mm all-in-one liquid cooler with three 140mm PWM fans and a vibration-dampened pump. Designed for high-performance CPUs on current AMD and Intel sockets.

Design and Build

The cooler uses a 420mm aluminum radiator with black fins and a copper base plate. Three 140mm fans with beige frames and brown rotors mount to the radiator for a total height of 55mm. Tubes measure 420mm in length.

Performance and Noise

The ceramic-bearing pump operates between 750 and 3400 RPM, producing 5 to 14.9 dB(A). Each fan reaches a maximum of 24.8 dB(A). Three pump profiles let you prioritize silence or cooling headroom for sustained workloads.

Features and Connectivity

Fans and pump connect via standard 4-pin PWM headers for motherboard control. The NL-PNA1 damper isolates pump vibration from the case. No RGB lighting is included.

Compatibility and Installation

SecuFirm2+ hardware covers AMD AM5, AM4 and Intel LGA 1851, LGA 1700 sockets. The mounting system is designed for secure, straightforward installation on current platforms.
