I'm really interested in finding out what is considered "normal" temps for the PB 12" 1.5GHz. At complete idle with no apps open, my CPU/GPU combo varies between 41/48C and 43/50C. Not really a problem in itself, it's just that the fan kicks in at 42/49C. As I have a SSD fitted the machine is blissfully silent when the fan's not running but every couple of minutes silence is rudely interrupted! If necessary, I'll open it up (again) and re-do the thermal compound (again) but the temps don't seem to be particularly high for the fan to be starting up. Any thoughts?
