if it is a pc cooling fan then it should have a built in controller inside.so simply hook up red in positive black in negative and it will start running and if u want some extra features in it https://www.instructables.com/id/Using-Diodes-for-Fan-Control/ check it out have fun

is there any part number on it? if so google the part number and look for stuff otherwise if you find nothing, it's probably just 12 volts on red, ground on black.

and the white is the speed sense pin. Hook up 12 volts to the fan - it should turn.
