The fan and frame use programmable micro-control ARGB lamp beads, and a mirror ring light effect is added to the upper and lower frames of the fan, which is suitable for motherboard light synchronization, which means that DIY computers can be more colorful! Supports motherboard PWM to control computer fan speed to keep your system cool at all times. The intelligent temperature control speed can be dynamically adjusted from 800RPM to 1800RPM. High airflow, low noise fan blade, balanced 7-blade design, increasing the output air pressure to improve cooling efficiency, hydraulic bearings to high-speed operation, reduce wear and tear, reduce noise and improve service life. Support ARGB motherboard divine light synchronization Support , Microstar, Chiao Jia, Qing +5V 3 PIN motherboard synchronization.
