Thank you! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1 x Fan 1. 5V ARGB AURASYNC: ARGB color lamp beads support motherboard lighting synchronization. The motherboard synchronization pin male and female header design, adjacent fans can be connected in series or adjacent fans can be connected in series with other light effect devices. 2. Low Noise Magnetic Suspension Bearing: The magnetic suspension bearing technology with low friction coefficient has a longer service life than traditional bearings. 3. PWM Intelligent Temperature Control: The fan speed can be dynamically controlled within the range of 600-2500rpm to reduce noise. 4. Rubber Shock-absorbing Pads: 8 shock-absorbing rubber pads are added at the 4 corners to effectively reduce the resonance noise between the fan and the chassis.
