Key Features
Near-Silent Light Wings LX Fans
Three 120mm Light Wings LX high-speed PWM fans spin up to 2100 RPM for 61.8 CFM airflow, yet stay whisper-quiet from 17.3 dB(A) at low speed thanks to be quiet! acoustic tuning.
360mm Aluminium Radiator
A 397 x 120 x 27mm aluminium radiator gives high-core-count CPUs plenty of sustained cooling capacity, with 400mm tubing for flexible routing in tall cases.
High-Flow 6-Pole Pump
A powerful 6-pole 3-phase pump (adjustable 3000-5500 RPM, 4-pin PWM) over a copper cold plate moves heat quickly and efficiently off the CPU.
Customisable ARGB Design
Each fan carries 16 addressable LEDs with daisy-chain wiring, plus 10 included pump-cap lighting foils so you can personalise the look — ARGB lighting, not an LCD.

Buyer's Guide
Buy it if
You want quiet 360mm cooling with ARGB Light Wings fans and a customisable pump cap, at a sensible price without an LCD.
Skip it if
Your case only fits 240mm/280mm radiators, or you specifically want an LCD pump display or a white cooler.
Also consider
The standard Pure Loop 3 for a different pump design, or an LCD-equipped 360mm AIO if a screen is essential.
