Typically, 5-V fans will require that 3.5 V or 4 V be applied to get them started, but at that voltage they will be running at close to full speed, with a very limited range of speed control. Electric fan, 1.8 liter. What these systems all have in common, besides significantly smallerand still decreasingsize, is that the amount of heat they must dissipate does not decrease; often it increases! From the standpoints of acoustic noise, reliability, and power efficiency, the most preferable method of fan control is the use of high-frequency (>20 kHz) PWM drive. Power consumption of the fan is less when it is running at less speed and. Electric Fan all. The notes and diagrams.for single fan applications, use the provided 30 amp fuse. (You must log in or sign up to reply here. However, in recent years, the technology of using these fans has evolved significantly. The tach signal indicates whether the fan is running and its rate of speed. This means that there is no indication as to how fast the fan is runningor indeed, if it is running at all. Thus, while the ideal tach is representative of the actual speed of the fan, the PWM drive in effect chops the tach signal output and may produce erroneous readings.
