FanBus Drawings For DigiDoc
One of the problems with using a DigiDoc 5 is that it only lets you turn fans on and off according to a set point. Since there are some fans that you don’t want to completely shut off, such as CPU fan, it would be nice to slow them down to make them quieter. I decided to use a fairly standard fanbus design but add the ability for the DigiDoc to automatically switch the fans to high (12 volt) if it reaches the set point temperature.
Note: These drawings are just theory at the moment, I haven’t built one yet. Use at your own risk.

All connections finally made. I like using jumper wires instead of solder blobs, it’s easier.
I just used some 20ga. wire I had sitting around. Are we having fun yet?
(When working with spaces this close take your time and check often for short circuits)
All switches and lights wired up. The pushbutton switch at the end is for a reset switch
since my case doesn’t have one. I only had a 3.5” slot available and couldn’t find a box
the right size so I made one out of scrap sheet metal and trimmed a blank cover so it was flat.

Installed and working.
