Vary the speed of your DC motor with this inexpensive circuit. Gear boxes can be costly and series resistors may cause stalling and overheating. This circuit delivers the voltage to DC motors with pulses and the speed is controlled via pulse-width modulation (PWM). Enclosure case NOT included.

    Fan speeds should be determined by your fan control not by the mode it is controlled. Whether it's PWM or DC shouldn't make much difference, since fans need 40% voltage to spin, a 1000rpm DC controlled fan can't go slower than 400rpm, while PWM fans are controlled by the separate PWM signal while staying @12V all the time and usually have a speed range of 20-100%.

PWM Fans. PWM stands for Pulse Width Modulation. This is a 4 pin connector rather than the more traditional 3 pin fan header but gives the fan control via the motherboard header. You can set the cooling parameters in the BIOS of your system and the speed of the fan will change depending on the temperature.

Pulse Width Modulation or PWM technology is used in Inverters to give a steady output voltage of 230 or 110 V AC irrespective of the load. The Inverters based on the PWM technology are more superior to the conventional inverters. The use of MOSFETs in the output stage and the PWM technology makes these inverters ideal for all types of loads.
