Key Features
 
Near-Silent 140mm Pure Wings 3
Two 140mm Pure Wings 3 high-speed PWM fans reach 1800 RPM for a strong 72.2 CFM airflow, tuned by be quiet! for quiet operation even under load (36.6 dB(A) at full speed).
 
Refillable Coolant Design
A dedicated refill port lets you top up the coolant over time, helping maintain performance and extend the cooler’s working life — a signature Pure Loop feature.
 
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.
 
Clean, Understated Look
A minimalist black design with no RGB keeps the focus on quiet performance, ideal for stealth or professional builds where lighting is not wanted.
