Just to make sure I'm getting my connections right, I'm assuming that "E1_T" is "extruder 1 temperature sensor", "E1_HOT" is "extruder 1 heating element", and "E1_F" is "extruder 1 fan". Is that a pretty safe bet?

I also noticed 2 connectors "MB_F" and "MB2_F" which I assume is "motherboard/mainboard fan 1" which makes sense because one of them is plugged into a little fan that is pointing roughly diagonally at the motherboard, but I don't see a second fan, but it's definitely plugged into something. Any ideas?
