When the temperature drops below a threshold again, the fans are turned back off. Temperature inside the chassis is checked, and if an outside-of-range temperature is detected, fans are set to their maximum speed. In this style of fan control, the fan is either on or off. Cooling fans equipped with either two- or three-pin connectors are usually designed to accept a wide range of input voltages, which directly affects the rotation speed of the blades. The color of the wires connected to these pins varies depending on the number of connectors, but the role of each pin is standardized and guaranteed to be the same on any system.

A variable rotation speed allows the cooling rate to be adjusted to meet demand, quietening the fan and saving energy when full speed is not required. Fan assemblies with this control input provide the ability to adjust the rotational speed of the fan without changing the input voltage delivered to the cooling fan assembly.

Control inputВ вЂ“ a pulse-width modulation (PWM) input signal, used when the cooling fan assembly has an internal motor driver circuit.

Sense (or tachometer) output from fanВ вЂ“ outputs a signal that pulses twice for each revolution of the fan as a pulse train, with the signal frequency proportional to the fan speed.

Vcc (Power)В вЂ“ nominally a +12В V supply, though it may be variable depending on fan type and desired fan rotation speed.

The first two pins are always used to deliver power to the fan motor, while the rest can be optional, depending on fan design and type: The common cooling fans used in computers use standardized connectors with two to four pins. If done properly fan noise can be drastically reduced. This must be done cautiously, as excessive reduction in speed may cause components to overheat and be damaged. Since fan noise increases with the fifth power of the fan rotation speed, reducing revolutions per minute (RPM) by a small amount potentially means a large reduction in fan noise.

Since they must move more air through the same area of space, fans will become more noisy.ДЇans installed in a PC case can produce noise levels of up to 70 dB. The byproduct of increased heat generation is that the fan(s) need to move increasing amounts of air and thus need to be more powerful. Power supplies needed forced cooling, and power supply fans also circulated cooling air through the rest of the PC with the ATX standard. Processors in most early x86-based computers, up to some of the early 486s, did not need active ventilation. Heat production varies with system load, where periods of compute-intensive activity generate much more heat than the idle time does. Computers emit this electrical power as heat generated by all major components.
