How can we control speed of a fan?

The speed can be controlled two ways – controlling the voltage to the adjust lead or controlling the resistance between the adjust lead and the return. Either pulse width modulation or a variable voltage/resistance can accomplish either method.

How do you control the speed of a 12V fan?

Here is a simple mod to allow the speed of any 12V fan to be varied. All we need to do is insert a rheostat or variable resistor in the 12V wire to the fan. The rheostat should be rated at least 3 Watt, (for fans up to 10Watt), and have a resistance of 20 – 50 Ohms.

Can you control fan speed with voltage?

DC voltage control is the method to vary DC fan speed and this can be implemented by incorporating resistances in the supply wire. The voltage drop across the series resistor reduces the voltage reaching the fan supply pin, automatically slowing the speed of the fan.

What is fan PWM?

“PWM” stems from electrical engineering and is short for “pulse width modulation”, which is also known as “pulse-duration modulation”. What it means is that you can use it to almost freely control the RPM of a fan. The speed of regular fans can be modified by voltage regulation.

What is PWM fan connector?

PWM stands for pulse width modulation. PWM fans and/or pumps are found in some CPU coolers and GPU (aka graphics card) coolers. They use an integrated circuit to control the speed of a fan or pump and, therefore, how much cooling it’s providing to the CPU or GPU.

What kind of fan do I need for a fan alarm?

A fan or motor with a “3 rd wire” that senses pulses generated by a Hall Effect device installed in the fan is required for the TachScan or TachStrip line of fan alarms.

Why does the speed of the fan affect the alarm sensor?

It is important to note that the alarm and speed sensors share the same supply voltage as the motor and its commutation electronics. Any changes in supply voltage to control the speed of the fan will also affect the commutation electronics and the speed/alarm sensors. Figure 3a.
