I opened my mac mini to switch the DVD with another hard drive and I forgot to take a picture with the ways the 3 thermal sensors are connected.

THeir codes on the mainboard look like:

  • J5550 - left one, when you look from the front of the mini (dvd opening towards you)
  • J5520 - middle one
  • J5560 - right one - the closest to the two sata connectors

  • One of them is for the DVD

  • One of them is for primary HDD near the connect
  • One of them for the primary HDD on the other side (glued)

How do I pair them? It's important as I do not want to mess the logic of power management.
