The ARCTIC F12 is number 6 in this guide, and it is the cheapest way onto the list once you count fans rather than boxes. The listing is for a five-pack at £18.66, which works out at £3.73 a fan — the lowest per-fan figure in the article, and less than the £18.99 a single be quiet! Light Wings costs.

The awkward part is what the listing does and does not put in the same unit. ARCTIC quotes noise as 0.3 Sone, while Noctua quotes 25.1 dB(A), be quiet! 31 dB and Corsair 36 dB, so those numbers sit in different scales and cannot be ranked side by side. ARCTIC does at least quote airflow twice over, at 53 cfm or 90.1 m3/h, at up to 1,350 rpm and 1.0 mmH2O static pressure. The rating is 4.6 from 1,639 ratings, and the breakdown shown on the page adds up to 100 rather than 1,639, so those bars are percentages. Everything on this page comes from the Amazon listing rather than from any testing of our own.

## Questions people ask

**How many fans come in the box?**

Five. The ARCTIC listing gives a number of items of 5 and a unit count of 5.0 for the F12 five-pack.

**Does the five-pack save money?**

The listing says the five-pack is how you save, and the maths agrees: £18.66 for five ARCTIC F12 fans is £3.73 a fan.

**How loud is the ARCTIC F12?**

ARCTIC quotes 0.3 Sone. That is not the same unit as the dB(A) and dB figures the other fans in this guide are quoted in, so the two cannot be ranked against each other.

**What airflow does the ARCTIC F12 produce?**

53 cfm, or 90.1 m3/h, according to the technical data in the listing, at a fan speed of up to 1,350 rpm.

**What bearing does the ARCTIC F12 use?**

A fluid dynamic bearing with an oil capsule, which ARCTIC says avoids lubricant leakage and gives a longer service life than a sleeve bearing.

**What connection does the ARCTIC F12 need?**

A 3-pin header at 12 volts; the listing gives the wattage as 1.21 watts.
