Rank #6 in Best Case Fans 2026: 9 Ranked by What a Fan Actually Costs
ARCTIC F12 120mm Case Fan, 5 Pack (£3.73 a Fan)
Price and rating as shown on Amazon when we collected them. Both change.
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.
How those 1,639 ratings break down
An average hides its own shape. This is the spread behind the 4.6 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“If you are populating a multi-fan system chassis or refreshing an older air-cooling setup without burning through money on decorative RGB lighting, this 5-pack of Arctic F12s remains one of the best value-to-performance options on the market.The core strength of these 120mm units comes down to pure acoustic efficiency and airflow output. Pushing up to ~53 CFM per unit, they move a substantial volume of fresh air into the case while maintaining a remarkably low acoustic profile. The fluid dynamic bearing operates with almost no motor whine, so even with all five installed to balance intake and exhaust pressure, the sound profile remains a steady, low-frequency hum rather than a high-pitched buzz.From an installation and utility standpoint, the build quality is clean and functional. The black frames and impellers are minimal, rigid, and devoid of unnecessary trim, fitting into standard 120mm mount points without flexing. Running a full bank of these drops system ambient and GPU thermal baselines significantly compared to stock single-fan setups.The primary setup constraint comes down to board connectivity and fan control. Because these are standard 3-pin DC fans rather than 4-pin PWM units, speed adjustment relies on board voltage regulation rather than direct pulse modulation. If your motherboard lacks sufficient 3-pin fan headers or DC-mode fan curve support, you will want to pick up a basic powered fan hub or splitter extensions to keep cable routing clean across the back panel.Overall, if you need straightforward, reliable, and low-noise air delivery for a home system build or server chassis, this value pack delivers stellar utility per pound. It gives you everything you need to solve thermal bottlenecks cleanly without paying a premium for lights or flashy branding.”
Verified purchase“Price and quality are incomparable in my opinion. The fans are sleek, silent and strong. In fact they are the strongest of all the fans in my unit. The ATX box I bought came with 3 fans, but I needed 2-3 more, so I bought these to add them up. I ended up replacing them all because these were so much better.”

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.
