Bottom line: The ARCTIC P12 PWM PST (5 Pack) - PC Fans, 120mm Case Fan, PWM Sharing Technology (PST), Pressure-optimised, Quiet Motor, Computer, 200–1800 RPM (0 RPM <5%) - Black is a specs-and-price decision rather than a crowd-consensus one in the cooling & fans category, priced around $28.99. Check the specification table above against one or two close alternatives — on price and spec fit, not on star ratings.
OPTIMISED FOR STATIC PRESSURE: During the development of the new P12 PWM PST, special emphasis was placed on a focused airstream and thus a high static pressure 200 TO 1800 RPM REGULATED VIA PWM PST: Thanks to 4-pin connector, the RPM can be regulated in a broad spectrum via PWM, noise is kept at minimum while maximum cooling performance is given when needed MORE EFFICIENT TECHNOLOGY: The motor is powered by a Neodym-Iron-Boron-Magnet ring of the newest generation, which allows the new P12 PWM PST to run much more efficiently than its predecessors
SpecPicks Verdict
SpecPicks scored ARCTIC P12 PWM PST (5 Pack) - PC Fans, 120mm Case Fan, PWM Sharing… using a rating × review-volume × price-fit model applied to our editorial and benchmark analysis across the cooling & fans category. ARCTIC's cooling & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for cooling & fans of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the Amazon listing before purchase. Prices, stock, and Prime eligibility update directly from Amazon's catalog and may have moved since this page was last verified.
Frequently Asked Questions
Do all five fans plug into one motherboard header?
Yes. PWM Sharing Technology lets you daisy-chain the fans, so the whole 5-pack can run from a single 4-pin PWM header and follow one shared speed curve.
Are these good for an AIO radiator or just case airflow?
They are pressure-optimised, rated at 2.20 mmH2O static pressure, which is the spec that matters for pushing air through radiator fins and dust filters, not just open case airflow.
How loud are they at full speed?
ARCTIC rates them at 0.3 Sone at the top of the 200-1800 RPM range. Below 5% PWM duty they stop entirely at 0 RPM, so idle is silent.
Will they work if my motherboard only has 3-pin fan headers?
The fans use a 4-pin PWM connector. On a 3-pin DC header they will spin, but you lose PWM speed regulation and the 0 RPM stop feature.
Is the 5-pack worth it over buying single fans?
At $39.99 for five, it works out to about $8 per 120mm fan, and the PST cables are included so you do not need to buy a separate splitter hub.

Key Features
- OPTIMISED FOR STATIC PRESSURE: During the development of the new P12 PWM PST, special emphasis was placed on a focused airstream and thus a high static pressure
- 200 TO 1800 RPM REGULATED VIA PWM PST: Thanks to 4-pin connector, the RPM can be regulated in a broad spectrum via PWM, noise is kept at minimum while maximum cooling performance is given when needed
- MORE EFFICIENT TECHNOLOGY: The motor is powered by a Neodym-Iron-Boron-Magnet ring of the newest generation, which allows the new P12 PWM PST to run much more efficiently than its predecessors
- EXTENDED LIFE SPAN: A 10 °C lower motor temperature roughly doubles the life span of a fan, the new ARCTIC motor has a four times longer service life through its low coil temperature
- TECHNICAL DATA: 5 Pack, Fan speed: 200–1800 rpm (0 rpm <5 %), Airflow: 56.30 cfm | 95.65 m³/h, Noise Level: 0.3 Sone, Static pressure: 2.20 mmH₂O, Pin: 4-pin
