Verdict
be quiet! Pure Wings 3 140mm PWM
6 / 10 Expert Rating
A perfectly adequate budget 140mm fan, but the rifle bearing means it's not the one to buy for a decade of runtime.
SilverStone AP121
6 / 10 Expert Rating
A competent, unremarkable fan best chosen for brand consistency in a SilverStone build rather than outright performance.
