The be quiet! Pure Wings 3 120mm PWM High-Speed is a single 120mm case fan, listed at £9.99 and sitting at number 5 in this guide. It is the entry where the pack arithmetic that runs through the rest of the list does not apply: the listing's own fields read Number of Packs: 1, Number of Items: 1 and Unit Count: 1.0, so £9.99 is the price of one fan, not a share of several. That makes it the clean point of comparison when the five-packs elsewhere are quoted per fan.

What the listing claims for that money is 59.6 CFM of airflow at 30.9 dB, up to 2.41mm/H2O of static pressure and a top speed of 2100 RPM. Two details are worth flagging. The airflow is given in cubic feet per minute, not cubic metres. And the 4.7-out-of-5 average comes from 569 ratings, while the star breakdown on the same page adds up to exactly 100 across the five bands — 84, 10, 2, 2 and 2 — which reads as percentages rather than counts. Every figure on this page comes from the Amazon listing; we have not tested the fan ourselves and have no measurements of our own.

## Questions people ask

**Is £9.99 the price of one fan or a pack?**

One fan. The listing's own fields read Number of Packs: 1, Number of Items: 1 and Unit Count: 1.0, so the £9.99 covers a single 120mm fan rather than a multi-pack.

**How loud is the Pure Wings 3 120mm PWM High-Speed meant to be?**

The spec table quotes 30.9 decibels and the product highlight describes "very quiet operation". The reviews shown on the same listing describe it as "very quiet indeed unless hitting 100%" and "super quiet" even when the PC is pushed.

**What is the airflow figure, and in what unit is it given?**

59.6 cubic feet per minute, listed as CFM. The listing gives no cubic-metre figure for this fan.

**Will it work on a radiator?**

The listing says the closed loop motor keeps the fan working against resistance such as a fan grill or a radiator, and quotes up to 2.41mm/H2O of air pressure, which be quiet! calls "the best choice for water-cooled and air-cooled systems alike".

**What do the 569 ratings look like?**

The average shown is 4.7 out of 5 from 569 ratings. The star breakdown on the same page totals exactly 100 across the five bands — 84 five-star, 10 four-star and 2 each for three, two and one star — which reads like percentages rather than counts.

**What connector and power does it need, and how long is it claimed to last?**

A 4-pin connector at 12 volts, drawing 3.6 watts, with a maximum speed of 2100 RPM. The listing claims an average lifespan of 80,000 hours on rifle bearing technology; the warranty field on the same page only says "Other".
