ARCTIC
ARCTIC P12 Pro A-RGB LN 120mm PWM Fan - FDB, 450-2000 RPM
The ARCTIC P12 Pro A-RGB LN 120mm PWM Fan is built for enthusiasts who want capable case cooling without intrusive noise. Its LN (Low Noise) tuning prioritises a balanced ratio of airflow and quiet operation rather than chasing peak speed figures. With 12 addressable RGB LEDs and a fluid dynamic bearing, it suits builders who want both lighting and long-term acoustic comfort.
Why this product
Wide PWM range with zero-RPM stop
Speed adjusts progressively from 450 to 2000 RPM via a 4-pin PWM connection, and the fan stops completely when PWM drops below 5% — useful for passive cooling phases.
Fluid Dynamic Bearing for quiet longevity
The self-lubricating FDB reduces operational noise and vibration, and an extended shaft improves pressure distribution for smoother, longer-lasting performance.
Automated balancing for reduced vibration
An automated measuring and balancing process applies balancing compound with pinpoint accuracy, noticeably reducing vibrations across the speed range.
83 m³/h airflow at 25 dB(A)
The redesigned rotor blades deliver higher airflow and static pressure at low speeds, achieving useful performance while keeping noise to 25 dB(A).
A-RGB Gen2 lighting with daisy-chain support
Twelve A-RGB Gen2 LEDs illuminate the frame, and the 3-pin A-RGB plug plus socket lets multiple fans be chained without extra adapters.
Six-year warranty
ARCTIC backs this fan with a 6-year warranty, reflecting confidence in its bearing and motor design for long-term continuous use.

Best for
- Quiet build enthusiasts who prioritise low noise over maximum airflow, benefiting from the LN tuning and 25 dB(A) operation.
- A-RGB builds where per-fan lighting and daisy-chaining reduce cable clutter.
- Long-term reliability seekers who value a fluid dynamic bearing and a 6-year warranty.
- PWM-controlled systems that can use the full 450–2000 RPM range and benefit from the zero-RPM stop feature.
Trade-offs
- Maximum airflow builds: the LN series intentionally avoids extreme peak RPM values in favour of quiet operation, so high-static-pressure radiator duty at maximum performance may suit a different fan line.
- Non-PWM systems: full speed control requires a 4-pin PWM header; 3-pin DC headers will not deliver the same range.
- Non-A-RGB lighting ecosystems: the 3-pin 5 V A-RGB connector is not compatible with 12 V RGB headers.
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.
