Usually, "sensors-detect" gives you some tips for loading the right 
modules for your board and once you load them, starts working.

Maybe that "fancontrol" is the service provided by lm-sensors, but not 
sure :-?

I would try first to get an accurate temperature measure for the CPU (69°
C is a bit high, even for a laptop, but not critical -that depends on the 
microprocessor type-). Are you able to get these values from BIOS? Just 
to make a comparison...
