About the Arctic F12 PWM PST CO 120mm Black Case Fan
Efficient PWM Control
One of the key features of the Arctic F12 PWM PST CO fan is its PWM control. The fan’s speed is regulated by pulse-width modulation, which allows for fine-tuning of the fan’s speed and noise levels. This feature is particularly useful for users who want to strike a balance between cooling performance and noise output.


Patented PWM Sharing Technology (PST)
The patented PWM sharing technology (PST) is another feature that sets the Arctic F12 PWM PST CO fan apart from other cooling solutions. PST enables the fan to be daisy-chained with other compatible fans, allowing them to share the same PWM signal. This means that multiple fans can be controlled by a single PWM signal, simplifying the management of the fan system.

Extended Life Span
The premium quality dual ball bearing allows continuous operation 24/7 without the slightest compromise in performance. Dust and high temperature are affecting this bearing a lot less than generic sleeve or one ball bearings and thus make it the perfect choice if reliability is key. The CO case fan’s life span is up to 5 times longer compared to models using a generic bearing.
Maximum Quietness
Even at low speeds the operating sound of the new ARCTIC motor is barely noticeable. Due to a sinus-magnetizing the new motor only creates about 5 % of the vibration from commutation of a regular DC-motor without filter.

Optimised Blade Design
The fan’s optimised blade design is another standout feature of the Arctic F12 PWM PST CO fan. The fan blades are shaped to produce high airflow with minimal noise. This design makes the fan ideal for use in environments where noise levels need to be kept to a minimum, such as in a bedroom or a home office.
