1. SILENTFAN: The MFDB fan has eight soft silicone pads at the 4 corners to absorb vibrations at high speeds. The maximum noise is only 25.5dBA, equivalent to the sound of falling leaves. Let you refuse noise disturbance while working or gaming.
2. HYDRAULIC BEARING: The cooling fan utilizes ultra MFDB fluid dynamic bearing bearings. With low friction coefficient magnetic levitation bearing technology, it has a longer life than traditional bearings, and the bearing life can be up to more than 10,000 hours.
3. PWM AND ARGB FUNCTION: It can dynamically control the fan speed in the range of 800‑2500rpm to reduce the noise.PWM pin can be inserted into SYS_FAN pin, and the motherboard synchronization pin is inserted into the motherboard and 5V D G pin.
4. 7 BLADES: 7 high pressure fan blades at 2500PRM with airflow up to 26.5CFM. The case fan focuses on improving performance, delivering stable air pressure and powerful airflow.
5. EASY INSTALLATION: The computer fan is compatible with all types of chassis, easy to install. Humanized power supply interface design, easy to install and use, hole spacing of 72MM (Note: hole spacing is the distance between the center points of the two screw holes).
