be quiet! Pure Wings 3 140mm PWM (140mm/62.8 CFM/1.3 mmH2O Static Pressure/1400 RPM Max/23.4 dBA/Rifle Bearing/No RGB/PWM) Review
For the 140mm size of be quiet!'s entry-level Pure Wings 3, this is the fan people are usually asking about when they want a cheap, quiet fan from a name-brand cooling company.
We'd stock a case with these for basic front-to-back airflow on a budget build, but wouldn't reach for them anywhere the fan needs to fight through a filter or radiator.
Budget Positioning
Pure Wings 3 is be quiet!'s value line, using a simpler rifle bearing instead of the fluid-dynamic bearings in their Shadow Wings and Silent Wings ranges, which keeps cost down at the expense of long-term bearing life.
Comparison to Alternatives
The be quiet! Pure Wings 3 120mm PWM already in this catalog is the smaller sibling; buy the 140mm version wherever the case supports it since it moves more air at a similar noise floor. Against the Arctic F14 PWM, pricing and performance land close, with the Arctic usually cheaper in multi-packs and the be quiet! fan running marginally quieter at idle.

Expert rating6 / 10
A perfectly adequate budget 140mm fan, but the rifle bearing means it's not the one to buy for a decade of runtime.
Best for
- Budget builds needing basic 140mm airflow
- Front or rear case fan replacement
- Quiet office PCs without heavy loads
Not for
- Radiator or high-restriction duty
- Long-term 24/7 workstation use
- RGB builds
