ARCTIC P12 Pro A-RGB LN 120mm PWM Fan 3 Pack - ACFAN00347A
The ARCTIC P12 Pro A-RGB LN 120mm PWM Fan 3 Pack is designed for silent enthusiasts who want balanced cooling performance without extreme noise. Each fan uses a hydrodynamic bearing and revised blade design to deliver strong airflow and static pressure at low speeds, with a speed range optimized for quiet operation down to just 25 dB(A).
Why this product
Balanced performance tuned for silence
The LN series avoids extreme peak speeds in favour of a 450–2000 rpm range that keeps noise at ≤25 dB(A) while maintaining 83 m³/h airflow and 6.9 mmH₂O static pressure.
Fluid Dynamic Bearing for reliability
Self-lubricating FDB minimizes vibration and noise during operation, supporting a 6-year warranty and long service life.
Precise manufacturing reduces vibration
Automated balancing and high-precision measurement ensure minimal gaps and smooth, efficient cooling performance.
PWM control with wide adjustment range
Progressive speed control via 4-pin PWM connection allows adjustment up to 2000 rpm; the fan stops completely below 5% PWM for zero idle noise.
A-RGB lighting with cable splitter included
5V 3-pin A-RGB connector lets you synchronize lighting across fans; a cable splitter simplifies wiring in the 3-pack.

- Works with any motherboard or fan controller that supplies 4-pin PWM (standard on modern boards).
- A-RGB lighting synchronizes with 5V 3-pin A-RGB headers; motherboard RGB software support varies by manufacturer.
- Operating temperature range is 0–40 °C; do not use in environments below 0 °C or above 40 °C ambient.
Best for
- Silent PC builds where noise matters more than maximum cooling output
- Low-noise case fans that still deliver strong airflow and static pressure at modest speeds
- Systems where PWM control allows precise fan speed matching to thermal load
- Enthusiasts who want A-RGB lighting control and cable organization in a 3-pack
Trade-offs
- Extreme overclocking or sustained high-performance cooling where peak airflow at maximum RPM is required
- Environments or installations outside the 0–40 °C operating temperature range
- Systems without PWM fan headers; these fans require 4-pin PWM connectors
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.
