How do i monitor case fan speed

[turbocookie]

I cannot find a way to monitor my pc case fans, im using the antec 902 gaming case, stock fans still. 4 pin connector fans with adjustable speeds.

Are your fans the original ones that came with the Antec 902?

How may wires are connected to each of the 4-pin connectors for each fan?

If the fans have only two wires (red/12V and black/ground) connected to them then there is no way to monitor their speed.

The white wire (speed sensor/tachometer signal) is required if you want to monitor the fan's speed.
