For those of you running temperature sensors (iStat Nano, etc), what are your hard drive temperatures? My G4 Digital Audio has 2 SATA drives mounted one in the factory position and one to it's immediate left, not stacked. They are both 7200 rpm drives. The boot drive runs at a constant 108F and the backup drive runs at around 106F. This seems hot, but I have no comparison temperatures. Thanks in advance.
