be quiet! Pure Wings 3 140mm 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.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

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
