i am planning on modding my black label delta so that i can still have rpm monitering, but use power from the psu via a 4 pin connector, so i need to know how the rpm pin on the header works. thanks 
 
<edit> not the board i was lookinhg for(i thought it was motherboards
) but i guess it's just as good
