Arctic P12 SLIM PWM PST Fan 120x120x15mm 300-2100 RPM - ACFAN00187A

Arctic P12 SLIM PWM PST is a slim 120 mm case fan aimed at compact and well-ventilated configurations. The operating range of 300–2100 RPM gives you wide control between almost silent operation and maximum airflow. With a flow rate of 42.10 CFM and static pressure of 1.45 mmH2O, it is a good option for places with more limited airflow. The black design and lack of RGB make it a practical choice if you are more interested in functionality than lights.

What you get is a 120 mm fan with a dynamic fluid bearing designed for long life and lower noise during prolonged operation. The range of 300 RPM allows for almost silent idle, while up to 2100 RPM you can ramp up cooling under serious load. The static pressure of 1.45 mmH2O helps air pass effectively through dense dust filters and case grilles. With noise levels up to 22.5 dBA, it remains relatively quiet even at higher speeds, which is important if your case is close to you on the desk. The power supply of 12 V / 0.12 A and 4-pin connector provide standard PWM support through the motherboard.

• Size 120 mm – the most common standard for fans, compatible with most modern cases.
• Speeds 300–2100 RPM – a wide range for quiet operation at low load and aggressive cooling when needed.
• Airflow 42.10 CFM – sufficient for effective intake or exhaust in a typical mid-tower or compact case.
• Static pressure 1.45 mmH2O – better airflow through filters, grilles, and denser panels.
• Noise level 22.5 dBA – aimed at quiet operation, suitable for gaming and office environments without annoying noise.
• Dynamic fluid bearing – reduces friction and wear, helping for longer life in 24/7 operation.
• 4-pin PWM connector – allows automatic speed control through the motherboard based on temperatures.

Who is this suitable for – if you are looking for a reliable 120 mm case fan focused on balancing noise and cooling, this model fits well in gaming and work configurations. It is also suitable for systems that run for long periods, where bearing and lower noise matter. If you are after a purely visual RGB effect, the lack of lighting here may be a downside.

The combination of wide RPM range, decent static pressure, and quiet profile makes Arctic P12 SLIM PWM PST a practical choice for stable airflow without unnecessary extras. Just a fan that gets the job done and lasts long.
