Hello. Do I need to have a speed controller if I have a temperature controller (IGS020)?

Thank you.

You only need a speed controller if:

1) Your fan is to noisy. Using a speed control will slow the motor of the fan thus making it run quieter.

2) If your fan is to powerful. Again, the speed control will slow the fan motor also reducing the CFM of you fan.

I just wonder using speed control can reduce wattage usage. Thanks
