Yellow wire on case fans

Couldn't quite see this covered in another post so here goes.

I have just bought myself a new fan controller, and i want to use it to control 4 fans. CPU, GPU, HD fan and rear fan. All of my fans except the HD fan have three wires, a red and a black for the power and then a yellow one which seems to be responsible for relaying the speed of the fan to the controller. Is there any way of modifying my HD fan s that it can do this too?

That is pretty much what I figured, but I thought I'd check with the experts first. Cheers.

Does the yellow wire always provide feedback? The on from the fan on my Radeon x850 pro is hooked up to my fan controller, but I'm getting no feedback.

thanks for the info. My fan has three wires, not four. Actually the third is white and not yellow, i connected it to the yellow wire on my controller though and it works fine, except for the feedback.
