Can I have the fan come on at a voltage higher than 0 V?
Can I have the fan come on at a voltage higher than 0 V?
Yes.
The idle speed is roughly 10 times the voltage at which the fan will come on. For
example, if you have your idle speed set to 40 percent, the fan will come on at
4 V; if you have it at 80 the fan will come on at 8 V.
