Who each one is for
The be quiet! Pure Wings 3 140mm PWM suits budget builds needing basic 140mm airflow and front or rear case fan replacement, though it is the wrong buy for radiator or high-restriction duty and long-term 24/7 workstation use. The Corsair LL120 RGB is the one to take for iCUE-based RGB builds and case intake/exhaust with visible ring lighting, though it is not the pick for high-restriction radiator duty and silent builds. Our rating of the be quiet! Pure Wings 3 140mm PWM (6/10): A perfectly adequate budget 140mm fan, but the rifle bearing means it's not the one to buy for a decade of runtime.

A perfectly adequate budget 140mm fan, but the rifle bearing means it's not the one to buy for a decade of runtime.
