Are these temperatures too high?

    Hello everyone..

    I have an old 2009 Macbook Pro Intel Core 2 duo and the computer has been feeling really hot.. I already did clean installs, cleaned the fan area by removing the fan but those did not change anythind..

    What else should I try?

    Your CPU is 100% utilized, you'll see pretty high temps in that situation.

    Mobile silicon can and will run up to 100 to 105C when taxed to the limit. Those temps are actually quite cool for a 100% loaded CPU.

    Yup, like everyone said, it's pretty low relatively. Mine reaches 94-96*C sometimes, until the fan kicks in until my ears die.

    From the screen shot, you're pushing the computer hard - what are you doing to see the CPU pegged at 100%?

    Given the hard work the CPU is doing (and thusly generating heat), the temps are not too bad.

    the fans appear to be going full bore, so there's really not much you can do at this point and 79c is not terribly hot for a system that's running at 100%

    I see high temps too.... Right now I am typing this with @ 15 Safari tabs going, with Mail, Calendar, and a few other small programs running, and my temperature is idling at 135-145 F (@57-62 C).

    I'm using a 13" 2011 Macbook Pro, in a hengedock running a 24" Monitor. I often see temps of 200 deg (93 C) when CPU use hits 80-100% usage... The fan ramps up to 6200 rpm.

    Is this normal to see the temps climb quickly within a few seconds to 200 F (95 c) when the cpu hits 80-100% capacity?

    Thanks a million. IAN :)

    Yes, the CPU itself is tiny and the heatsink is pretty small too, it's a matter of seconds before they both heat up and the fans kick in.

    Completely normal.

    I would also consider changing the thermal paste and adding thermal pads.
