high room temperature for extended periods

s it safe to leave a g5 running in a room at, say 30 degrees celcius, for *months on end*, say at low cpu usage, say around 20%?

Is it safe to leave a g5 running in a room at, say 30 degrees celcius, for months on end, say at low cpu usage, say around 20%? The fans tend to make a lot of noise in the summer when it's warmer, and I'm wondering whether I might break the machine.

Does the G5 have an automatic emergency shutoff if the temperature (CPU or othercise) gets too high? If so, what temeprature(s) of which sensor(s) triggers such a shutdown?

Thanks for any help.

Let me see if I understand this. You want to know if it's safe to leave a G5 running within the temperature range Apple states it's safe to operate in. Um, now why would Apple list ranges of operating temperatures if they did not want you to run the computer within that range?

Well... the g5 gets really noisy when the temp goes up. To me, it sounds like the machine is struggling to stay cool, and it's not a very healthy sound.

Back to my question... is the g5 smart enough to shutdown if it is overheating?

No.

You'll break the machine.

Does the G5 have an automatic emergency shutoff if the temperature (CPU or othercise) gets too high? If so, what temeprature(s) of which sensor(s) triggers such a shutdown?

Apple says not to use it at certain temps. Most people would consider their statement a Big Clue(tm).

Thanks for any help.

Don't know about the G5 dual, but my iMac G5 survives that each summer in the tropics. Fans will ramp up the harder you drive it. CPU temps normally around 55C, and you are starting to have trouble when it hits 72C.

Using X Resource Graph to track temperatures.

You will hear the fans roar? Not sure it it decides to put the CPU into sleep mode when it gets too hot, as I have always noticed heating problems and located the program causing the problem.

Well, obviously the fans will be working harder if you are operating your machine nearer the upper range of acceptable ambient temperature range ... that's what they are there for. It would be very strange if the fans did not kick in when you were working in hot temperatures.

Yes, the G5 is smart enough to manage it's own temperature ...

No.

Why? 30 Celsius is well within the stated range of 10 to 35 C.

And 30 Celsius is well within the stated range of 10 to 35 C.

Perhaps an automotive analogy is appropriate. If you buy a 4-wheel-drive SUV and only drive it around town on paved roads, it will last much longer than the same vehicle driven exclusively on very rugged back roads, an authorized and encouraged use.

It's also well documented that computer chips fail in relation to the 4th power of the absolute temperature. Always running a computer near the top end of the authorized range will likely result in sooner failure. So the question becomes, how long do you intend to keep the computer?

Yes, the Mac will shut itself down if it gets too hot, but there is no guarantee that some damage won't have been done getting to that point.

You are, of course, correct. My error.
