ARCTIC BioniX P14 A-RGB 140mm PWM Case Fan Black 400-2500rpm 110CFM 5.4mm H2O Fluid Dynamic Bearing 16 LEDs

⚠ You need a 3-pin 5V addressable (A-RGB) header on your motherboard. A 4-pin 12V RGB header is not compatible — the plugs can be forced together and doing so destroys the LEDs. No controller or hub is included in this pack, so a board without an A-RGB header needs an ARGB controller bought separately. Mind the header budget too: ARCTIC states no more than 3 fans on a 2 A A-RGB header and 5 on a 3 A header, and for PWM no more than 3 fans on a 1 A header, 6 on 2 A and 9 on 3 A. This fan uses a plain 4-pin PWM connector — it does not have ARCTIC PST; daisy-chaining is done with the bridge modules instead. Depth is 28 mm, not the usual 25 mm — check clearance in slim cases and against RAM. Radiator screws are not included; use the ones supplied with your AIO.

✓ Radiators and restricted intakes where static pressure matters

✓ AIO liquid coolers

✓ Front intakes behind a dust filter or mesh panel

✓ Builds with several fans that need tidy cabling

✓ Adding or replacing a single fan in an existing array

✓ Systems with a motherboard A-RGB header and lighting software

Two things about this range are easy to get wrong, and both change what you should buy. The first is that ARCTIC PST is gone. Every previous generation of ARCTIC fan chained through a 4-pin pass-through socket, and virtually every listing still says PST out of habit. These use a bridge module instead — a card that clips between neighbouring fans and carries the PWM power and the A-RGB signal in one, which is genuinely tidier but means the fans have to sit adjacent to chain. The Bridge Cable that links two separate arrays across a case ships only with the three-packs, so a build with a front trio and a top pair is best served by a three-pack plus singles rather than five singles. The second is the header budget: ARCTIC’s own limit is three fans on a 2 A A-RGB header, and a three-pack is exactly at that limit — a second trio needs a second header or a powered hub. On the fans themselves, P-series means pressure-optimised, so they earn their keep on radiators, behind dust filters and through mesh front panels rather than blowing into open air. At 140 mm the P14 is the airflow half of the pair: 110 CFM against the P12’s 76, at a lower 5.4 mm H²O and a lower 2500 rpm ceiling. ARCTIC describes it as optimised for liquid cooling, and it is the better choice wherever a 140 mm mount exists, since a larger fan moves the same air more quietly. Worth stating plainly: ARCTIC publishes no noise level, no MTBF and no cable length for this series, so any dB(A) figure you see in a listing has been borrowed from a different fan. If you are planning the rest of the cooling, our CPU coolers and power supplies pages cover the parts that sit alongside these.
