Blower resistors are resistors which are used to control the fan speed of automotive blowers. The fan speed can be changed either by switching the blower resistor resistance mechanically, using a rotating lever, or electronically by the air conditioning system.
Method One: Install Fan-Controlling Software. The most ideal way to control your fans is with something like previously mentioned SpeedFan (or, if you're on a Mac, previously mentioned smcFanControl). These will give you the most control over your fans, letting you choose how fast they're running at any given time.
