This schematic below presents a low cost, self contained analog circuit for fan speed control. It delivers a continuous and linear fan control voltage which is easily adjusted for any desired linear relationship between the van voltage and temperature.
By generating a variable supply voltage for the fan, this linear circuit measures temperature as well as controls the cooling fan’s speed.
