Description

Main

Connect to PC, switch, server, etc. Standard 3-wire fan: Gnd, 12V, Tach.

 

Fan

Passthrough Gnd and 12V to power a fan if desired.

 

Mode

This switch changes the tach signal mode.

  • V+: Tach signal is pulled to +5V or +12V (depending on input fan voltage) 2x per "revolution" of the fake fan. Used in PCs.
  • GND: Tach signal is pulled to ground 2x per "revolution" of the fake fan. Used in Cisco Switches.

 

Speed

Adjust simulated fan speed: Approximately 4,700 to 17,200 RPM.
