WebStandards. To determine which standard a motherboard uses for the tach signal, check the voltage across the pins on the motherboard fan socket with an oscilloscope; there should be 0 V (ground - black), +12 V (power supply - red). For the tach signal, the wire is usually yellow or white, and an oscilloscope will show a +5 V square wave output.
