ARCTIC F12 PRO PWM PST - 120mm Fluid Dynamic Bearing Low Noise PWM Controlled Case Fan with PST Feature & Anti-Vibration System

The ARCTIC F Series is a high performance case fan for anyone looking for a quiet and efficient case fan.
Long Service Life
The Fluid Dynamic Bearing comes with an oil capsule that avoids lubricant leakage. Thus this bearing is as quiet as a sleeve bearing but comes with a significantly higher service life
Perfect Case Fan Regulation with PWM
The PWM function allows the motherboard to run the fan precisely at its necessary speed. This guarantees the required cooling and minimizes the noise level.
Patented PWM Sharing Technology (PST) Lowers Noise
If you want to improve the cooling efficiency of your computer you get several case fans working in parallel (since it takes 10 fans to double the noise level). But what does it help if they don't work together? The PST assures that all of your fans listen to one control signal. E.g. you share the CPU Cooler's PWM signal and assure that your case fans stand down at low load and spin up whenever necessary.
Innovative Design Enables Quiet and Efficient Ventilation
The innovative design of the fan blades improves the air flow and facilitates a highly efficient ventilation. The impeller was designed with a focus on minimzing the noise level yet delivering the desired airflow and pressure.
Patented Anti-Vibration-System
A unique anti-vibration system in combination with the patented fan holder ensure a near-silent operation.
