The measurement methods for the quality of heat dissipation fans include:
1. measurement of current, speed, starting voltage, input power, locking current, air flow and pressure data, and noise standards;
2. Swivel lock protection, fans with low current or Auto start function, fans with high current or without Auto start function, free drop units, insulation impedance and insulation strength.
Among them, the fan protection test includes rotating lock protection and low current or fan with Auto start function, as well as testing of free falling single unit and insulation impedance.
