120mm 4pin PWM Case Fan MFDB Dynamic Pressure Bearing 500RPM to 1800RPM PC Cooling Fan for Computer Case Black

Feature: 1. QUIET: The MFDB fan has eight soft silicone pads at the 4 corners to absorb vibrations at high speeds. The maximum noise is only 26.5dBA, equivalent to the sound of falling leaves. Let you refuse noise disturbance while working or gaming. 2. HIGH EFFICIENCY HYDRAULIC BEARING: The PC cooling fan utilizes ultra sturdy MFDB dynamic pressure bearing. Adopting low friction coefficient magnetic levitation bearing technology, it has a longer service life than traditional bearings, and the bearing life is more than 10000 hours. 3. PWM INTELLIGENT TEMPERATURE CONTROL: MFDB PC fan, can dynamically control the fan speed in the range of 500rpm to 1800rpm to reduce noise. PWM pin can be inserted into SYS FAN pin. 4. 15 BLADE DESIGN: 15 high pressure fan blades deliver airflow up to 52.9CFM at 1800PRM. PC case fan focuses on improving performance, delivering stable wind pressure and powerful airflow. 5. EASY INSTALLATION: PC case fan is compatible with all types of chassis, easy to install. Humanized power supply interface design, install and use, 105mm parallel hole spacing, 148mm diagonal hole spacing (hole spacing is the distance between the center points of two screw holes).
