    Alreet,

    Just wanna run this by someone...

    I know these computers run hot. Mine is a 2.8ghz stock model. When in Bootcamp playing Sims 3 with settings all on full, the CPU temp reaches around 80oC and GPU around 90.

    I know the chips can handle up to like 105oC so im not really worried. Does mean you have to put the computer on something when its hot or it burns yer legs.

    Any thoughts?

    I think manufacturer's no longer call them laptops because they don't want them on your lap. So keep a tray in between or keep it on a table :)

    ummm

    I am pretty sure the OP's temperate was in Celsius not Fahrenheit. That can make a huge difference. And do answer your question OP, you are completely fine

    151 degrees at only idle...? We're talking about 2.8GHz right, with a sped up fan...?

    I wonder what would happens when one stresses a 3.06GHz variant... :eek::eek:

    That's weird that the 2.8 gets that hot. I own the 2.66 17" MPBuni and it would get up to around 70-80 degrees working on Photoshop CS4 and lightroom. I've never seen it go past 100 yet.

    my MBP 15 inch 2.66 unibody gets up to like 70 C after playing age of empires for a long time.

    also what is the widget that you guys are using to get all those temperatures?

    I keep hearing this rationale: that Intel specs its chips at 105 degrees so it's OK if the chip is running at 80 or 90 degrees. Heat is not the friend of electronic components. Even if the chip could handle 105 degrees for a period of time, I don't think it's good for the chip to be running at high temps for long periods, it's not good for the surrounding components, and extreme thermal cycling is bad too. Just because my car's engine has an 8000 rpm redline doesn't mean my engine will last very long running at 8000 rpm for sustained periods.

    My new 13" MBP hit over 80 degrees just ripping a CD using iTunes before the fans even got up to 2500 rpm. I'm tempted to use a third party fan control program if Apple is insistent on valuing quiet fans over ridiculously high temps.

    It must be safe though for the hardware. Granted it probably shortens the lifetime of the hardware, but I bet by the time the hardware fails cause of heat exposure, the computer will be considered out dated by a long standard (i.e. 10 years).

    I have always run SMCFancontrol on my Apple notebooks. Works a treat. I have had the uMB 13" and now the 17" uMBP and both, when put under load get really hot to the touch - but so far neither has had any problems. touch wood!
