solder a Tach wire on a D5/MCP655 Vario

well, i just found you can solder a wire to a spot on the pcb of the D5 vario pumps for a rpm sensor. i'm not sure how well known it is, i've never seen anyone talk about it. so i though i would post it here.

Link to guide/thread.

thanks to Diverge for asking and confirming it works.

Maybe when I do my annual tear down, I may look into this mod. It would be good to have an RPM sense on my D5, and it doesn't look too hard. I could just run that up to the CPU fan header, and monitor it with something like SpeedFan or whatever the Gigabyte software is.
