Q: Safe Imac operating temperatures.

Hi,

 

I've searched google and looked at some older posts but haven't really been able to find what im looking for.

 

i was wondering if there is a list of what the min to max safe operating temps are for intel imacs (aluminum).

 

i have a 3-4 yr old intel 24" alu imac that's recently been shutting down and i think it's due to overheating.

 

i downloaded temperature monitor and these are my readings after turning on my computer (after it has been shut down all night).

 

ambient air - 24C/75F

cpu A heatsink 35C/95F

CPU Core 1 - 33C/91F

CPU Core 2 - 33C/91F

Graphics Processor Chip 1 - 43C/109F

Graphics Processor Heatsink 1 - 43C/109F

Graphics Processing Temperature Diode - 45C/113F

Hard Drive Bay 1 - 36C/97F

Main Logic Board - 38C/100F

Power Supply Position 1 - 53C/127F

SMART DISK WDC WD5000AAKS-40TM0 - 34C/93F

Wireless Module - 58C/136F

 

It's pretty cold atm but lst ngiht the upper left corner on the back was quite hot and the rest of the back was also warm. i put a a little fan behind and turned it on and it brought the temps down a little.

    Scroll through these threads to see my various posts on temps, smcFan Control etc. You can also run a fan at the back of the computer, which will help cool things down. That said, if the ambient temp is very hot, no amount of blowing hot air around is going to help.

     

    You should also post all the temps. The ones you've given don't look that bad. "Just watching a movie"--
    a movie is very graphics and CPU intensive. You should expect the temps to go higher.

    Thank you for your reply.

    Of course I do understand blowing hot air arount wont do the thing. I just wanted to know if having like 65+ on the power supply might be considered normal. Mainly because its more than the CPU temp;

     

    COU Heatsink 51

    GPU HS 49

    GPU temp dio. 53

    Mem controller 52

    Optical 46

    Power supp 65

    Disk 54

     

    Ambient is like 27 or so, this is why I'm concerned.

    The upper body of the iM gets really hot.

     

    Thank! M.

    The PS at 65C (149F) isn't bad. Watching a movie or a Flash video, as compared to simply browsing, will raise all the temps. The drive is just at the top of the normal operating temperature range for most drives. That said, I don't like to allow mine to stay for very long in the upper 40s or near 50.

     

    I think you your temps are all normal for what you are doing.

     

    You can expect the case to get hot. This is what I do to help cool things down.
