The Noctua NF-P12 redux-1700 PWM is a single 120mm fan, 25mm thick, running on 12V through a 4-pin PWM connector at up to 1700 RPM. At £12.95 it takes the top spot in this guide, and it is one of the few entries where the price on the page is the price of exactly one fan: the listing's own fields say Number of Packs: 1 and Unit Count: 1.0 count, so there is no pack to divide by.

The number that stands out is the one that cannot be lined up against anything else. Noctua quotes a maximum of 25.1 dB(A), while the ARCTIC packs in this guide quote 0.3 sones, be quiet! quotes 31 dB and Corsair 36 dB — three different units inside one comparison. Noctua is also the only brand here quoting airflow in cubic metres rather than CFM, at 120.2 cubic metres per hour. Every figure on this page comes from the Amazon listing for this fan, not from any testing we carried out.

## Questions people ask

**Is the £12.95 price for one fan or for a pack?**

The listing's own fields say Number of Packs: 1 and Unit Count: 1.0 count, so £12.95 is the price of a single NF-P12 redux-1700 PWM fan.

**How loud is the Noctua NF-P12 redux-1700 PWM?**

Noctua quotes a maximum of 25.1 dB(A) at 1700 RPM. That figure cannot be lined up with the ARCTIC fans in this guide, which are quoted in sones, or with the Corsair fan quoted at 36 dB.

**Why is the airflow given in cubic metres instead of CFM?**

The Noctua listing gives 120.2 cubic metres per hour. Every other fan in this guide is quoted in CFM, so the two sets of numbers are not directly comparable.

**What connection does it need?**

A 4-pin PWM header on 12 volts, which supports automatic motherboard speed control — the listing describes powerful airflow when required and virtually silent running at idle.

**How long is the warranty?**

The listing states a 6 year manufacturer's warranty, and an MTTF of more than 150,000 hours.

**What is included with the fan?**

The Included Components field lists the NF-P12 redux-1700 PWM itself. The redux edition is the streamlined version, and Noctua lists anti-vibration mounts, S-ATA adaptors, y-splitters and extension cables as optional accessories.
