LOADING...

The be quiet! Pure Wings 3 BL105 is a black 120mm PWM case fan for desktop PC builders who want quiet, adjustable cooling, with low minimum-speed operation and a maximum speed of 1,600 RPM.

Recommended For

  • PC builders adding a 120 mm intake or exhaust fan for everyday case ventilation who want PWM speed control and a low minimum speed for quieter operation.
  • Quiet-focused PC builders who need a standard 120 mm case fan for airflow behind a dust filter; a review found its noise profile suitable for case ventilation and noted the frame can help reduce air escaping around the fan on restricted mounts.
  • Builders who prefer a plain black, non-illuminated fan for a subdued PC interior rather than a lighting-focused showcase build.
  • Users replacing a case fan in a modest- to moderate-cooling setup who value controlled airflow more than the highest available fan speed; testing found the standard-speed model usable on a radiator, though better suited to case ventilation.

Real-World Use Scenarios

  • Adding a 120 mm intake or exhaust fan to a desktop case: it provides another path for case airflow, and PWM control lets the motherboard adjust cooling as system temperatures change.
  • Keeping a PC quieter during everyday or lighter workloads: a low fan-speed setting can provide case ventilation without running the fan at full speed; how audible it is depends on the rest of the system and the fan curve.
  • Helping manage heat during gaming or other demanding use: the fan can ramp up with a PWM curve to move more air through the case, though the result also depends on case layout and the other cooling components.
  • Replacing a fan on a compatible radiator: the optimized frame is intended to support radiator use, and testing found acceptable cooling, but the standard-speed model may not match more performance-focused fans in demanding radiator tests.
  • Adding an airflow fan to an existing build: its standard 120 mm size and 4-pin PWM connection make it a practical option when the case has a matching mount and the motherboard or fan controller has a suitable header.
