Thanks, I hope it inspires others to do the same.Wow! This turned out very nicely! Great work!

Thanks, Yes these are my favourites too.I really like your first two planed improvments.
1st: You should be able to do this cable by your own (I was lazy and bought a ready PWM splitter cable). Keep in mind that the mainboard can't provide enough electric power for a big number of fans. If you want to control more than 3 fans get the electric power directly from the power supply. Make sure u have PWM fans!
2nd: I would like to see that! Thats the way my old MacPro 1.1 worked…

The fans I have already installed are NOT PWM so would have to replace the four of them for your approach to work. What I was trying to do was find a circuit to convert a PWM signal to a DC voltage in range 6-12v, but haven't found anything to do this.
The fans I used have three wires. Black and Red provide 12V and must be connected in parallel for the fans to function. The Yellow wire is a tachometer signal back to the motherboard (which I dont use at this time), but wiring these in parallel wouldn't work. A single yellow wire is all that is needed, one can be left unconnected. If you want a wiring diagram I could do one.great work, also on details..
``I then installed new Fractal Design 92 mm fans into the bracket, using new rubber mounts into the existing holes. I cut the cables to the fans and spliced both fans into s single cable and used paracord to sheath the cable back to a three pin fan connector.
When splicing a fan cable in this way, only a single yellow wire should be connected.``
what does this mean in detail, why only one single yellow wire? As I understand what you did is just paralleling the two fans into a single connection..
