The fan also has a tachometer to monitor blade revolutions per minute (RPM). The tachometer outputs a pulse
voltage signal. The pulse multiplied by 30 yields fan RPMs. The RPM should be near 4500 in full power mode and
2500 in low power mode. In addition to the tachometer output wire, there is a pull-up wire (power input). This
allows a user-defined maximum output voltage from the tachometer, and facilitates interfacing with multiple
measurement devices.
