Long Service Life The hydrodynamic plain bearing is equipped with an oil capsule so that loss of the lubricant is avoided. For this reason, this bearing is as quiet as a plain bearing but has a significantly longer service life. Perfect Fan Regulation The PWM function signals via the motherboard exactly at which speed the fan must run. This guarantees maximum cooling performance with a minimum noise level. PWM Sharing Technology If you want to improve the efficiency of your cooling in the PC, you can also connect several case fans in parallel (the noise level is only twice as loud with 10 or more fans). But what does that help you if they don't work together? The PST function ensures that all case fans work on a signal. For example, you share your CPU cooler PWM signal and thus ensure that your case fans only turn up and down when necessary. Innovative Design for Quiet and Efficient Ventilation The innovative design of the fan blades improves the air flow and the possibilities for significantly more efficient ventilation. The fan wheel has been designed with a focus on minimal noise and offers improved airflow and pressure.
