Temperature Monitor

Last month’s DoubleClick had an article about the

beneﬁ ts of getting rid of poten-

tially harmful computer heat and

included a section on replacing the

fan in my G4 Sawtooth power sup-

ply. (That operation was a com-

plete success but I wouldn’t suggest that sort of thing to everybody.) In this

issue I have a little utility from

Marcel Bresink Software-Systeme

that will

help you check up on the temperature of speciﬁ c components on your modern

Macintosh and can even warn you if temperatures get too high.

Temperature Monitor is an application to read out all accessible temperature

sensors in Macintosh computers. Not every Mac has these sensors and some

models have more than others. The Temperature Monitor reports results from

ﬁ ve sensors in my little iBook: Battery, Graphics Processor Die, Power Sup-

ply / Memory Bottomside, Processor Bottomside, and the Toshiba hard drive.

The program can visualize the history graphs of the readings, display mea-

sured values in a large variety of fashions, or announce readings by speech

output. It can also store and export values in chart form. As you can see from

the extensive row of buttons in the Preference panel below, there is more to

Temperature Monitor than just a digital thermometer.

Temperature Monitor is the small FREE version of the application Hardware

Monitor. Just a little taste of what Hardware Monitor can do. Hardware Moni-

tor can additionally display “non-temperature” sensors and artiﬁ cial operating

system probes, or control external LCD panels. Temperature Monitor is part

of a software suite of 9 different monitoring applications which can be used

for numerous purposes. Hardware Monitor is an application to read out all ac-

cessible hardware sensors in Macintosh computers. Currently more than 100

different Macintosh hardware sensors and more than 200 hard drive tempera-

ture sensors are supported. The program can visualize the history graphs of the

readings, display measured values in a large variety of fashions, or announce

readings by speech output. It can also store and export readings. Depending on

what sensors are built into your Macintosh system, the following data can be

accessed by hardware Monitor:

• Temperature readings at different locations • Battery data of portable com-

puters • Voltage sensors • Current (amperage) sensors • Fan speed sensors

• Sensors for pulse-width controlled fans • Power and load sensors • Ambient

light sensors • User-deﬁ ned artiﬁ cial sensors to monitor the operating system

Hardware Monitor is electronically distributed software. You can download

the product and test it before you

decide to purchase an unrestrict-

ed usage license. Temperature

Monitor is electronically distrib-

uted software. I could ﬁ ll up a

few pages telling you all about it

but its best if you download your

own copy to see it in operation

for yourself. You can download

the product free of charge.
