Product Description:

Temperature Monitor is an application to read out all accessible temperature sensors in Macintosh computers. The program can display and visualize the values measured by Mac OS X in a large variety of fashions. Among others, the following operations are supported:

display in a default window
output in a screen display in front or in the background of the screen
tabular display in an overview window
display in the menu-bar
display in the Dock icon
graphical display of short-term and long-term history curves in an unlimited number of windows
speech output
display of minimum and maximum values
export to text or CSV files

Moreover, the application can display additional technical information about your computer. Among other information this includes processor type, processor and bus frequencies, and manufacturing information.

The application can read out the data only if your computer is equipped with the necessary sensors, and if Mac OS X can access them without needing third-party device drivers. Starting in summer 2002, Apple has begun to massively drive forward the use of monitoring probes in the PowerMac series, the Xserve series, and in portable computers. Some models are equipped with 38 and more sensors.

Temperature Monitor tries to detect all sensors on as many Macintosh computer types as possible. However, a prediction which sensors are available in which models is not possible, because Apple very often releases "silent product updates", where the hardware equipments of some models are changed but the names are not. The particular graphics card, hard disk configuration and operating system version is also important.

What's new in this version:

Due to quality problems and intellectual property issues, support for the third-party software "SpeedIt" has been removed. The application now comes with its dedicated own driver to access internal information of x86 processors. The driver can easily be installed or uninstalled from within the application. The program will automatically notify the user if installation of the driver is recommended.
The following additional sensors will be accessible on current x86-based Macintosh systems when the driver is active: the internal digital thermal sensors for each CPU core of Intel processors.
In addition, the System Information window of the application will be capable of displaying family, model and stepping numbers, as well as the internal identification of x86 processors after the aforementioned driver has been installed.
Added new preference values to adjust the ratio of the font sizes for display of the sensor labels in relation to display of the sensor readings. The preference settings are available for the sensor window and the screen display output channels.
The policy for detecting temperature sensors that are built into hard drives has changed: If the application detects a SATA drive under control of an Intel-based Macintosh system using AHCI, it will automatically assume that this drive contains a working temperature sensor compliant with the latest version of the ATA and S.M.A.R.T. standards. Up-to-date hard drives will no longer need explicit support by the application but will be accepted automatically. The column for temperature sensor support in the Drive Overview window has been removed.
The reference manual now gives an example on how to define a sensor alert trigger to automatically shutdown the system when readings exceed adjustable threshold values.
