Rank #1 in Best Case Fans 2026: 9 Ranked by What a Fan Actually Costs
Noctua NF-P12 redux-1700 PWM 120mm Quiet Fan
Price and rating as shown on Amazon when we collected them. Both change.
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.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I bought four of these for a PC case upgrade and was very happy with the results.The biggest difference compared to the generic fans they replaced was the noise level. These were noticeably quieter while still providing plenty of airflow for everyday use and gaming.As with most Noctua products, there is definitely a premium attached to the brand name, but in this case I felt the improvement in acoustics helped justify the extra cost.The grey redux colour scheme is also a nice option for people who want Noctua performance without the traditional brown and beige appearance.Overall, they performed exactly as I hoped and I'd happily buy them again in future builds.”
Verified purchase“Quiet and clean. The fans look nice and perform well. Nearly silent operation. My graphics card is the loudest thing in my case now.”

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.
