ARCTIC P12 Pro PST CO 120mm PWM Fan - Dual Ball Bearing
The ARCTIC P12 Pro PST CO 120mm PWM Fan is a high static pressure case and radiator fan designed for tight spaces where airflow resistance is high. Dual ball bearings and a refined blade design deliver durability and smooth operation across its full speed range. The included cable splitter enables daisy-chain connection for continuous operation without motherboard header limits.
Why this product
High static pressure for restricted airflow
At 6.9 mmH₂O, it pushes air effectively through radiators, mesh filters, and perforated panels where standard fans lose performance.
Dual ball bearing for long-term durability
Extended rotor shaft and dual ball bearing design maintain smooth operation even at sustained high speeds, with a 6-year warranty backing the construction.
Automated balancing for precision
Computer-controlled balancing during manufacture minimizes vibration and noise across the entire speed range.
PWM speed control with daisy-chain connector
Motherboard PWM control from 600 to 3000 rpm, plus included 4-pin socket for chaining multiple fans without consuming extra headers.

- Airflow131 m³/h (77 cfm)
- Static pressure6.9 mmH₂O

- Warranty6 Years
- SKUARC-3523
- EAN4895265000140
- Standard 120 mm case and radiator mounts (fits all Intel and AMD stock mounting brackets and most third-party coolers).
- 4-pin PWM motherboard headers on any modern PC (Intel or AMD).
- Fan controllers and hubs that accept standard 4-pin PWM connectors.
- The included daisy-chain socket supplies a duplicate 4-pin connector; only one fan in a chain can be speed-controlled via PWM — others run at the same speed as the first.
Best for
- CPU and GPU cooler radiators where dense fin stacks demand high static pressure
- Cases with mesh or perforated front panels that create airflow resistance
- Users running multiple fans and wanting to avoid motherboard header shortage via daisy-chain connection
- Systems prioritizing durability and low vibration noise over raw volume airflow
Trade-offs
- Large open-frame builds or exhaust-only setups where high airflow is more important than static pressure — a standard 120 mm fan may move more air at the same noise level.
- Environments hotter than 40 °C, as the operating range stops at that ambient temperature.
- Systems requiring completely silent operation at idle; the 3.3 V startup voltage and PWM control only reduce speed to 600 rpm minimum, not 0 rpm below 5% PWM.
Thanks to high static pressure, the Pro fans move air effectively through tight spaces. This makes them ideal for radiators, perforated panels, and mesh filters.
Revised fan blade design for an optimal balance of performance and smooth operation.
A dual ball bearing with an extended rotor shaft ensures high durability and maximum lifespan at high rotational speeds.
An automated measuring and balancing process ensures exceptional precision and smooth performance by applying the balancing compound with pinpoint accuracy.
