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.     Extented Life Span with Japanese Dual Ball Bearing The premium quality Japanese 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.     Two Way installation Blow warm air out of the case Draw cool air into your case
