Powerbook 12" Temps


i'm interested in finding out considered "normal" temps pb 12" 1.5ghz. @ complete idle no apps open, cpu/gpu combo varies between 41/48c , 43/50c. not problem in itself, it's fan kicks in @ 42/49c. have ssd fitted machine blissfully silent when fan's not running every couple of minutes silence rudely interrupted! if necessary, i'll open (again) , re-do thermal compound (again) temps don't seem particularly high fan starting up. thoughts?
 

mine has been idling several days @ 749 mhz.

output of "sysctl hw.sensors". fan not running.

hw.sensors.adt0.temp0=47.00 degc (remote)
hw.sensors.adt0.temp1=45.00 degc (internal)
hw.sensors.adt0.temp2=57.00 degc (remote)
