The last articles we had introduce the power for the cooling fans.

What's the Start Voltage?

Start voltage means: the first power supply voltage zero condition, turn the fan, the voltage rotate the knob, the voltage gradually increased, the fan start to the minimum voltage.

Because the voltage supplied board may be unstable, starting voltage is lower, ensures that voltage instability, can start the fan pressure activated.

Conventional 12V fans are starting voltage falls below 7 V ;
Conventional 5V fans are starting voltage falls below 3.5V;
