From what i know, checking of processor temperature, motherboard
temperature etc are done with software and utilities. And most of
them comes more accurate with temperature sensor that are actually
install very near to the processor, heatsink or GPU area. Unless
there's some mechanical heat sensing device on the hard disk or
inside the hard disk to send feedback, i wonder how accurate hdtune
can be in predicting the actual operating temperature of the hard
disk drive.
