Today we’re looking at the be quiet! Pure Wings. A product that the manufacturer claims offers an “outstanding price-performance ratio”. We’ll be the judge of that!


In the world of PC Assembly, every component plays its part in curating the ideal machine. The plethora of components available demands rigorous selection to ensure optimal compatibility. While fans might often be relegated to mere considerations of fit, their quality significantly affects the decision-making process. Be Quiet!’s assortment, undoubtedly, serves a variety of tastes, and the 140mm Pure Wings fans serve as a testament to this claim.

The be quiet! 140mm Pure Wings fans are a sterling addition to the brand’s repertoire. Their performance stands out, but what’s truly commendable is their quietude. True to their moniker, these fans whisper rather than roar. Sporting an elegant all-black aesthetic, they’re available in multiple sizes to complement various case dimensions. The 140mm might be the largest, yet its sound profile is impressively muted—offering minimal disturbance even if you’re on speakers rather than headphones.
