80mm PWM Case Fan Efficient Silent MFDB Dynamic Pressure Bearing Intelligent Temperature Control 800‑2500RPM Speed PC

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. 72mm 2.83in Bearing Type: MFDB Rated Voltage: 12V Rated Current: 0.16+ 0.02A Rated Speed: 800 2500RPM+ 10percent Airflow: 26.5CFM Function: 4PIN PWM.
