so what's CPU shutdown temp again?

thats 96-98C which according to istat (error given) i have surpassed...this is not good

dont worry, todays cpus will shut down before overheating
Even before they do, the computer will lock up because it will be to hot to handle data.
very true
op: if it were too hot your computer would definitly let you know performance wise
well it is more sluggish than normal, is that what you mean? things take longer to load and open while i am converting this movie but i imagine everyone's laptops do that
istat is whack or a thermal sensor in my computer is whack? the latter would be a hardware issue sounds like
no, not sluggish as thats expected if you are heavily taxing cpu
i am talking about computing errors and it freaking out. you would know it if it happened
example
this is my first laptop so i guess the "heat" thing is new to me but from the replies it sounds like its just the nature of the beast
You don't need to worry unless it looks like the computer is having an acid trip and or smoking (or doing the first as a result of the second
)processorfinder.intel.com
That site has a list of several things, including a max temp value (It's TcaseMax, IIRC). If you are unsure of your CPU's actual name, run this command:
and the kernel will give it to you.
Other notes: The CPU will throttle back if it is about to overheat, and will only shut down as a last resort. Shutdown does not happen at the temp that is in Intel's Processor Spec finder, I think that number is the point it starts to throttle. The shutdown point on the mobile C2Ds is closer to 110-120C. Lastly, the fan controller on most Intel Mac's seems to have been designed with a somewhat delayed reaction, probably to prevent the fans from spiking following a temperature spike. They take a moment to react to temp changes, and heavy load might make it go flying up for a few minutes. Once the fans start ramping up, it should come back down and stabilize in the 80s somewhere. At least, my machine does. (It hovers between 80-85 for me, different Rev's of MBP are probably a bit different in this regard)

I use the same macbook pro model as you do and my CPU temperature right now, while I am "handbreaking", is constant 68°C@ 5000rpm (20°C room temperature). If I would run handbrak without smc fancontrol CPU temps would go up to 85°C @3500rpm.
CPU load is @ 150% with enough reserves for youtube or other stuff. I am actually running handbreak and safari only.

huh
you realize that the cpu is the hottest part right
ok, you take it to apple and say what? my cpu is too hot but everything runs perfect, can you give me a new one? lol
