Most of my dash clicking stuff has been blend door actuators for the Heat/ac ducts but that doesn't really make sense with it changing with engine speed. Hmm.

The top suggestion as to the ticking/clicking noise from behind the dash was given to you.  You didnt even acknowledge the person giving you the help.  Did you look behind your dash? Did you check into the actuator problem?  I dont know of any sensors that would cause a ticking/clicking with speed that you would hear inside the cab, sometimes you can hear clicking from a relay, but never heard of it speeding up or slowing down.  The actuator is the best answer, and until you do something to see if that is the problem I dont think anyone is going to be able to help you narrow it down.
