You've got all the modules loaded that are needed and these are all
the sensors your hardware supports. Temp1 and temp2 are probably for
the chipset and motherboard. The way to find out which is which is to
observe them at certain loads, like high i/o that will heat up the
chipset, with the cover off to keep the motherboard cool. Whichever
temp is higher is for the chipset. This might be hard to do on such a
small system because everything is so close together.
