The be quiet! Pure Wings 3 BL109 is a 140mm PWM case fan for desktop builders seeking strong airflow for demanding cooling setups, including radiator use. It reaches 1,800 RPM, moves 70–75 CFM, and has a stated maximum noise level of 30.5 dBA.

Recommended For

  • Builders adding a 140 mm fan to a radiator or heatsink who want PWM speed control and a high-speed model designed to maintain its target RPM against airflow resistance.
  • Desktop builders improving airflow through a 140 mm case mount, especially where a dust filter or grille adds resistance; the high-speed version is positioned for higher air pressure than the standard Pure Wings 3.
  • Noise-conscious PC builders who will use a PWM curve to run the fan below maximum speed during everyday work, then raise speed when gaming or rendering increases cooling demand.
  • Builders who want a plain black, non-illuminated 140 mm fan for a functional airflow setup rather than a visible RGB-focused build.
