1. Hydraulic bearings have a longer service life than oil bearings2. It is used for air-cooled radiators to enhance the cooling power of the power supply and ensure the power supply3. Used for chassis ventilation, enhance chassis ventilation, and reduce hardware working environment temperature4. Used for heat dissipation of power supply, strengthen the wind power of power supply heat dissipation, and ensure stable energy supply5. Build an air duct, computer case convection heat dissipation: cold air is sucked in by the front panel fan, and hot air is drawn out by the rear fan6. PWM intelligent temperature control Fully automatic PWM speed control, which can automatically adjust the fan speed with the system temperature7. The aerodynamic and simple appearance can effectively reduce the edge airflow friction and improve the heat dissipation efficiency8. 13 fan blades, the air volume can reach 54.5CFM at full speed based on the hydrodynamic design of the blade shape9. Thickness is only 15mm, more suitable for compact space10. Rated voltage: DC 12V11. Rated current: 0.2A12. Bearing type: Hydro13. Noise: 26dB14. Air volume: 54.5CFM15. Speed: 300-1100RPM16.
