    I've read in the Apple specs that G5's and ACD's seem to be rated to operate up to 95 degrees (F). Has anyone had problems in temperatures higher than this?

    I ask because my apartment gets quite hot in the summer sometimes - very close to 95 since I have a very bad AC. I was experiencing some lockups this weekend coming out of sleep mode that I haven't seen since it has cooled down a bit, and was wondering if the heat could be the problem. (It was about 93 in my apartment this weekend)

    From my 3 minutes of research, all Macs made in the last 8 years have a max operating temp of 95°F. I've only noticed locking problems with an old iMac at high ambient temps. You should try to put your computer someplace that can get better air flow if you can't control the room temperature, and then only use it at night if you're concerned about overheating. It's more likely that the CPU(s) will shut down rather than melt. You can also download a temperature monitoring app like Temperature Monitor that will give you readings from all the sensors inside your PM.

    95 degrees is quite hot. I certainly would not want to be using my computer at temperatures that hot. Not because I would fear that something would happen to the computer, but I fear that I would drop too much sweat into the keyboard. :D

    The ambient temp in my computer room at my house is around 77 degrees and that is warm for me.

    I think that you need to invest in a better air conditioner. It will improve your comfort and the functioning of your G5.

    You'll probably here your fans speed up more, for the rest you should be fine.

    Living in an apartment where the AC is built into the wall, that is not an option :(

    The CPU temperature of my iMac G5 has gotten as high as 167 degrees with a steady CPU temp of as high as 162 degrees. I don't notice any problems with the computer locking up, or the display doing anything out of the ordinary. At these temps its just as bright and crisp as it is in normal operating temps, which are around 125 degrees.

    When I start playing games online with my iMac G5 and the CPU settings set to Highest it gets really hot after a while and the fans are quite loud. iMac G5's are anything but whisper quiet let me tell you. What actually gets really hot and makes the whole inside hot is the power supply. Mine gets really hot at times depending on what I'm doing.

    My G5 gets pretty hot but i guess it's normal. Right now my processor is about 140 degrees.

    I should also ad if you start reading thru that thread its not because of the temp of my comp, its because compusa screwed up my comp. ;)

    Besides at 95 degrees i'm usually out at waterworld or swimming. To good of weather to be on a comp. :cool:

    You can be 'ghetto' and buy a $10 house fan... anything that increases airflow will be happy company to your G5. If your fans don't come on very much then you are fine.

    how do you check the temperature of the processor? is there a built in program inside OS X or do you have to download one?

    ouch. that must suck being 95° indoors...its been about that hot outside this week and it's freakin oppressively hot...yeah, like jackieonasses said, a box fan or similar is quite good, but i tried putting one next to my crt and the picture got all messed up so i had to move it. i wouldn't imagine that's a concern with lcds though

    Just try to keep such magnetic fields away from your hard disks and such.

    :eek::eek:never made the connection that a magnetic field was interfering with the monitor. that's really good to know so i don't try anything like that again and kill my disk. wait--a gsm cell phone or w/e won't mess up my hard drive right, cause it seems to have a similar effect on my monitor when i get a call :confused:

    No, a GSm phone has interference with the signal... Not a magnetic pull.


    I doubt a small house fan could harm a hard drive.... But you better be safe. It would have to be one large magnet/fan to harm a screen or hard drive.


    your safe.

    But then I don't think that is because of the CPU temp but rather the whole thing in an "recommended zone" ;)

    Go to www.versiontracker.com and do a search for Temperature Monitor. The G5 Processor has temperature sensors on it. Most new Macs have hard drive temperature monitors on them as well.

    Yikes - I used to have a PC that I built myself... and the warning temperature was 75ºC... My G5 seems to have cooled down slightly since I started reading this thread, but good lord - I'm running Bittorrent (about 9 torrents) Safari, Mail, MSN Messenger (sorry), iCal, Address Book, iTunes, VLC, Quicktime, Word, Pages AND temperature monitor (not that any of these apps are actually doing much (other than Safari, Bittorrent and MSN)... I've got:

    Logic Board (Unchanging): 43.6º
    CPU A: 62.5º
    Processor Card A (unchanging): 48.2º
    CPU B: 60.0º
    Processor Card B (unchanging):44º
    Drive Bay: 32.5º
    Memory Controller: 54.2º

    The processors seem to get slightly toasty!!

    Oh, and why do some people talk in Farenheit? I guess it's to do with that you were bought up on? (If I'm the only one using Celsius, please excuse my ignorance!)

    That is what it says in my G5 Manuel "Operating between 35F and 95 F"

    My Dual 1.8 G5 CPUs get as hot as 168 degrees Farenheit.
    I don't notice any problems with the comp locking up or shutting down.
    Fans barely come on either.
    I guess that is just normal.

    Well PowerMac G5's have an excellent cooling system and a lot of room inside to move the air around, unlike an iMac G5. This is why you don't see a PowerBook G5 currently.
