ARCTIC P12 Pro PST LN 120mm FDB PWM Fan - 450-2000 RPM
The ARCTIC P12 Pro PST LN is a 120 mm case fan built for silent operation without sacrificing cooling performance. It uses a fluid dynamic bearing and optimised blade design to deliver strong airflow and static pressure at just 25 dB(A), making it ideal for builders who want quiet, reliable cooling.
Why this product
Quiet operation at 25 dB(A)
The fan balances performance with minimal noise through a hydrodynamic bearing, extended shaft, and revised blade design that reduce vibrations and motor noise.
Fluid Dynamic Bearing for longevity
The self-lubricating FDB minimizes wear and noise during operation, supporting a long service life backed by a 6-year warranty.
PWM control and synchronisation
Four-pin PWM connector with PST (PWM-based Synchronised) technology lets you link multiple fans to a single header for coordinated speed control.
Balanced speed range
Runs from 450 to 2000 RPM, tuned for steady cooling at low noise rather than extreme peak performance.
- Size120 mm
- Speed range450–2000 RPM
- Airflow83 m³/h
- Noise level25 dB(A)
- Bearing typeFluid Dynamic Bearing
- Warranty6 Years
- SKUARC-3531
- EAN4895265001154
- Fits any 120 mm case fan mounting position with standard four-hole pattern.
- Works with any motherboard or fan controller supporting 4-pin PWM headers.
- Safe for use in ambient temperatures from 0 to 40 °C.
- PST synchronisation requires multiple P12 Pro PST units connected in series to a single PWM header; solo operation uses standard PWM control.
Best for
- Silent PC builds where noise matters more than maximum cooling output
- Systems running at low to moderate load that benefit from quiet, steady-state cooling
- Multi-fan setups using PST synchronisation to simplify wiring and control
- Long-term reliability — the 6-year warranty and FDB design suit users planning to keep their system for years
Trade-offs
- Extreme overclocking or high-load workloads requiring maximum airflow; peak output of 83 m³/h is moderate, not extreme
- Users needing variable control without PWM; the fan cannot run below 5 % PWM signal and will stop entirely below that threshold
- Hot ambient environments above 40 °C; operating range is limited to 0–40 °C
Premium fan with a speed range optimised for silent enthusiasts. Instead of extreme peak values, the LN series focuses on a balanced ratio of performance and quiet operation.
Revised fan blade design for an optimal balance of performance and smooth operation.
A hydrodynamic bearing combined with an extended shaft ensures quieter operation by improving pressure distribution and minimizing vibrations.
An automated measuring and balancing process ensures exceptional precision and smooth performance by applying the balancing compound with pinpoint accuracy.
Reduces motor noise, compensates for load fluctuations, and protects against inrush currents and reverse polarity.
The fan delivers more performance at low speeds with higher airflow and static pressure at just 25 dB(A) – ideal for quiet, powerful cooling.
