Temperature Monitor Widget is the Dashboard version of its "bigger brother" Temperature Monitor. It is recommended that you use Temperature Monitor first before using the widget edition to learn more about the sensor equipment of your computer. The applications are designed to give you access to all temperature sensor readings Mac OS X uses to monitor and cool your computer.
On PowerPC hardware, support for S.M.A.R.T. hard drive sensors accessed
via SATA interfaces has been enhanced. The widget will now accept the temperature
sensors of unknown SATA drive models. (This has always been the standard
on Intel-based computers.)
The support for hard drive sensors controlled via proprietary drivers
of Sonnet and FirmTek has been enhanced.
The default number of displayed digits behind the decimal point is now
automatically set to zero in cases where it is known that the sensor hardware
does not provide more significant digits.
Corrected a problem where the temperature values displayed for the cores
of the Intel P7350 processor have been shifted by 15 degrees Celsius.
