12V DC 92mm x 92mm x 25mm Cooling Fan

Arctic F9 PWM PST CO

92mm PWM Fan with Cable Splitter for Continuous Operation

• 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.
• Maximum Quietness, Minimum Vibration: Even at low speeds, the operating sound of the new ARCTIC motor is barely noticeable. Due to sinus-magnetizing the new motor only creates about 5 % of the vibration from the commutation of a regular DC motor without a filter.
• 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 ten 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 airflow and facilitates a highly efficient ventilation. The impeller was designed with a focus on minimising the noise level yet delivering the desired airflow and pressure.
• Extended Life Span with Dual Ball Bearing: The premium quality dual ball bearing allows continuous operation 24/7 without the slightest compromise in performance. Dust and high temperature affect 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.
• Two Way Installation:
• Blow warm air out of the case
• Draw cool air into your case
