Splitting the RPM signal from a fan to two inputs?

[MichaelD]

Hey all. Strongly considering a Digidoc-type device. I want to attach my CPU fan to it, but I also want to be able to see the CPU fans' speed on screen via MBM. Do I just splice in another three pin connector, but just use the rpm wire?

Anyone do this before?

Do you need the RPM wire hooked up to the digidoc for any reason? If not just take it out of that connector and hook it into its own.
