be quiet! Pure Wings 3 140mm PWM Triple Pack Black - BL139
The be quiet! Pure Wings 3 140mm PWM Triple Pack is a set of three case fans designed for systems that need reliable cooling without noise. With rifle bearing technology rated for 80,000 hours and PWM control from low to high speeds, it suits builders who want steady airflow for gaming PCs or workstations.
Why this product
3 fans included
Pack contains three 140mm fans, enough to outfit most mid-tower cases or upgrade an existing setup.
Rifle bearing for longevity
Rated lifespan of 80,000 hours ensures it will outlast most system builds without degradation.
Optimized blade design
Seven airflow-optimized blades reduce turbulence while delivering high static pressure, useful on radiators or dense filter configurations.
Quiet operation range
PWM control allows very low minimum RPM for silent idle, ramping up only when needed.

- Works with standard 140mm case fan mounts using screw fixing.
- PWM connector (4-pin) integrates with any motherboard PWM header or PWM fan hub.
- Operates on 12V DC systems with voltage range 5–13.2V, compatible with standard PC power supplies.
- No daisy-chain connector; each fan requires its own PWM header or connection to a fan hub.
Best for
- Case cooling in mid-tower builds
- Radiator applications where static pressure matters
- Builders prioritising silent idle and low-noise operation
- Long-term reliability without fan replacement
Trade-offs
- High-speed cooling only: Maximum speed of 1200 RPM is moderate; extreme overclocking or server workloads may demand faster fans.
- RGB or lighting: No lighting connector or RGB capability; purely functional black fans.
- Tool-free mounting: Requires screws to mount; no push-pin or tool-free fixing.
With low minimum rpm and high top-end speed, Pure Wings 3 140mm PWM Triple Pack are the perfect addition to PCs for any application. The fans offer outstanding reliability and make for a long-lasting companion for your gaming system.
