Power Mac G5 Temperature

Message #1 - Posted 2005/11/30 - scribe

Hi all. Greetings.

I have a Power Mac G5 Dual Processor 1.8 GHz.

I was wondering if anyone knew or provide me with links to where I can obtain info regarding what the optimum and/or maximum (upper limit) temperatures are for CPU, Drive Bay, Main Logic Board. Memory Controller Heatsink, Processor Card, SMART Disk.

I live and work from South Africa. It can get pretty hot out here :)

Many thanks.

As on any computer, this is indicated in the tech specs:
http://www.apple.com/powermac/specs.html

* Operating temperature: 50∞ to 95∞ F (10∞ to 35∞ C) * Storage temperature: -40∞ to 149∞ F (-40∞ to 65∞ C) * Relative humidity: 5% to 95% noncondensing
* Maximum altitude: 10,000 feet

Here in Sweden, we may have very cold weather, in some places -10 C may be called a "warm day", and some guys have failed letting transported TV's warm up from subzero (C) temperatures before starting, and then they break, for sure. The currents in the integrated circuits depend heavily on the temperature. So make sure respecting those limits.

Hey guys . . .

Goto and download Temperature Monitor from
http://www.bresink.com/osx/TemperatureMonitor.html

and . . .
I asked a question and got this reply;

thank you very much for your interest in Temperature Monitor and your technical question.

Would you be so kind as to advise or direct me to info regarding what the optimum temp for a Power Mac G5 1.8 GHz. - i.e. for main logic board backside, main logic air inlet, ambient, cpu, etc.

Temperature Monitor comes with a very detailed reference manual (see the
menu item "Help"). As indicated in the chapter "Displaying sensor data",
the specified upper and lower limits for each sensor location can be displayed in the third and forth column of the window "Sensor Overview".

If no values are given, it does not make sense to specify limits for that
location, or there can be no "optimum" temperature. For example, the air
inlet sensors measure the temperature of the incoming air in your room. For
this reason they are very dependent on your room temperature. In this regard,
you should only make sure not to exceed the room temperature given in the
PowerMac manual, for most models 35=B0C.

I hope this information is helpful to you. If I can be of further assistance,
please let me know.

Best regards,
Marcel Bresink
