Hello everybody,
I want to maintain a constant temperature of 60 deg C to a heat dissipating surface, varying the speed of a fan. The surface is inside a box and the fan will blow outside air to the surface. A typical circuit will compare the voltage of thermistor on the hot surface to a preset and power the fan. My question is the following:
Is a typical pc class fan be able to provide continuously variable speed from 0 to max or do I need a dc motor?
Of course any suggestion on the whole project is welcomed.
Thanks in advance
