80mm PWM Case Fan Efficient Silent MFDB Dynamic Pressure Bearing Intelligent Temperature Control

Feature： 1. [Superior Silent Fan] MFDB fan has eight soft silicone pads at the 4 corners to absorb vibration at high speed. The maximum noise is only 25.5dBA, equivalent to the sound of falling leaves. Let you refuse noise disturbance while working or gaming. 2. [Efficient Hydraulic Bearing] The cooling fan utilizes ultra durable MFDB dynamic pressure bearing bearings. Adopting low friction coefficient magnetic levitation bearing technology, it has a longer service life than traditional bearings, and the bearing life can get more than 10,000 hours. 3. [PWM Intelligent Temperature Control] It can dynamically control the fan speed in the range of 800‑2500rpm to reduce noise. 4pin PWM pin can be inserted into SYS_FAN pin. 4. [7 Leaves Design] 7 high pressure fan leaves can deliver up to 26.5CFM airflow at 2500PRM. case fan focuses on improving performance, delivering stable aerair pressure and powerful airflow. 5. [Easy Installation] Computer fan is compatible with all types of chassis, easy to install. Humanized power supply interface design, start to install and use, hole spacing of 72MM (Note： hole spacing is the distance between the center of the two screw holes) Specification： Item Type： 80mm PWM Case Fan Material： ABS Size： Approx. 80x80x25mm 3.15x3.15x0.98in Hole Distance： Approx. 72mm2.83in Bearing Type： MFDB Rated Voltage： 12V Rated Current： 0.16+-0.02A Rated Speed： 800-2500RPM+-10percent Airflow： 26.5CFM Function： 4PIN PWM.
