Do you really need that level of complexity. Why not use your current code to poll the fan speed every so often.


I plan to add a couple of reed relays to be able to turn the system on and off also, I guess I can use pulsein however that will mean I have to wait for it to complete before I can do anything else (read temp, turn the system on/off change fan speed etc).  Though I guess that isn't really a problem.



You should be able to take the two pulseIn readings to get the duty cycle in well under a tenth of a second. In your application that should be more than fast enough.
