The be quiet! Light Wings BL135 is a white 140mm PWM case fan with ARGB lighting, designed for desktop PC builders who want airflow, motherboard-synced illumination, and quiet operation up to 25.5 dB(A).
Recommended For
- PC builders adding a 140 mm side or bottom intake who want reverse-blade airflow while keeping the fan’s ARGB side visible.
- White-build owners who want front-and-rear ARGB lighting and a fan that can be synchronized with compatible motherboard lighting.
- Quiet-focused gaming or desktop PC builders replacing a case fan, with PWM speed control to balance airflow and noise as system cooling needs change.
- Builders replacing a standard case fan who value coordinated lighting and quieter operation over a high-speed fan’s extra airflow; reviews of the Light Wings family found its standard-speed models suited to case-fan use.
Real-World Use Scenarios
- In a glass-sided build with side or bottom fan mounts, install it as an intake to bring cool air into the case while keeping the fan’s reverse-blade design and ARGB lighting visible from inside.
- When a gaming PC needs extra case airflow, use it as a side or bottom intake to feed fresh air into the system; the actual temperature change will depend on the case layout and the rest of the cooling setup.
- For a PC used for both quiet everyday tasks and demanding workloads, connect it to a compatible PWM controller so fan speed can rise when cooling demand increases and slow down when it does not.
- In a white-themed build, use the front-and-rear ARGB illumination to add visible lighting whether the fan is mounted as an intake or viewed from the opposite side.
- For a noise-conscious case build, use PWM control to balance airflow and fan noise; the manufacturer rates the fan at up to 25.5 dB(A) at maximum speed, though perceived noise depends on the case and other components.
