It's bad for the computer when it starts smoking.
Normal operating temperatures for the CPU core are 40-100ºC depending upon processor load. Thermal shut down occurs at a core temperature of 125ºC.Mac Pro 2.66 Ghz; MacBook Pro C2D 2.33 Ghz; MacBook Pro 2.16 Ghz, Mac OS X (10.4.10), Intel iMac C2D 17 "; MacBook 2.0 Ghz; 30 GB iPod Video (Black); iPod Nano 2 GB
Yours is running cooler than mine and I have never had any issues at all.
Your Mac will shut down well before any permanent damage is done.15" 2.4GHz MPB, 4GB OWC RAM, 160GB HDD, Mac OS X (10.4.10), OWC Mercury Elite Pro USB/FW drive, Brother HL-2040 laser printer
It really depends on what you're doing and which MBP you have. Generally speaking, processor temperatures should be around…
- 60ºC/140ºF for general usage such as e-mail, web browsing, word processing etc.
- 80ºC/175ºF for more demanding tasks like audio encoding (iTunes), video work, gaming and so on.
Be aware that these are only ball-park numbers so will vary depending on your own MBP, your exact usage and the ambient temperature (the higher this is the hotter your MBP will run). Not everyone's MBP will heat up the same even with the exact same configuration and usage.
PS These number are for C2D based MBPs. Those MBPs with the original CD processors can probably add another 10ºC or so to those figures.Mac Pro 2.66GHz 5GB/4x300GB/ATi X1900 XT/AE/BT/2xSD ; Dell 2405FPW, Mac OS X (10.4.10), MacBook Pro 15.4" C2D 2.2GHz 2GB/120GB ; Mac mini CD 1.66GHz 2GB/80GB/SD
The heatsink is directly connected to a CPU/GPU to draw heat away from that processor using either a passive (conduction) else an active (usually a fan) method.
By the way, the "general usage" temperature can be as low as 40ºC/105ºF for some owners although generally this is rare and requires modifying the fan behaviour. One should expect to be in the range from 50ºC/122ºF through to 60ºC /140ºF though. The trick to having low temperatures is to keep CPU/GPU activity to a minimum. This can't always be helped but careful consideration as to how you manage your software and what you put on your MBP can go a long way to keeping it cooler. Also, running off battery will keep your MBP cooler.Mac Pro 2.66GHz 5GB/4x300GB/ATi X1900 XT/AE/BT/2xSD ; Dell 2405FPW, Mac OS X (10.4.10), MacBook Pro 15.4" C2D 2.2GHz 2GB/120GB ; Mac mini CD 1.66GHz 2GB/80GB/SD
is there a certain point on the MBP that lets heat out? such as a fan escape? because it burns my legs! i glanced at the caution and it mentioned heat- but not this kind of heat!MacBook Pro, Mac OS X (10.4.10), 4 GB RAM
Just to clarify a bit about CD (vs. C2D) heat...
The original Core Duo MBPs maintain the same internal temps, with an ideal 80 C upper limit. Not any hotter than the Core 2 Duos.
The only difference is that the Core 2 tends to be a bit more efficient, so tends to generate those temps at a slower rate, and I'm pretty sure that the later machines maintain a higher "lower limit" for fan speeds.
There's no question that the Core 2s run cooler to the touch, but I think that this is due to the fact that the fans are always pumping more air, even at idle. My CPU temps at idle (with a CD machine) are not significantly more than those reported for C2Ds, but my machine is almost always hotter to the touch.
In fact, the Core 2s are rated 10 degrees (C) higher than the Cores: 110 C thermal limit vs. 100 C for the original Core Duo.

my problem is not that the CPU gets hot. I guess all laptops with C2D do.
My problem is that the area just left of the mouse pad gets pretty hot. The HD (I have the 7200 RPM) is located here, so I'm not really sure what to do about it, I mean, I can lower the temp of the CPU with FanControl or CoolBook, but I can't really alter the HD… it needs to run!MacBook Pro 2.4, Mac OS X (10.4.10)
does anyone know what TIM Apple is using between the HS and the CPU?
i wonder if its possible to swap out with Artic Silver or some of the new Diamond pastes.
I know when i did this on my HTPC my temps dropped 5-7°C not a big deal but my old Northwood core (in a desktop that is) never gets above 50°C and usually runs around 30ish°CHTPC WMC05, 17" SR MBP 4Gig RAM (self installed), Mac OS X (10.4.10)
I have the same problem. I have had two other 2.33GHz machines before and it didn't have nearly as much heat radiating off of the laptop. Don't know what to do about it either even though I have only had this for two months. Quite disappointed that Apple would ship something like this to be honest.Macbook Pro 2.4GHz, Mac OS X (10.4.10)
yeah this hot macbook pro issue has been bothering me for quite some time now. especially where i live (philippines, a tropical hot country), even if youre in an air-conditioned room, the macbook still gets hot, so i have a mini fan just for it. lol anyways, ive gotten used to it, i have what you call speed ball risers, theyre amazing! or i put my macbook on a book riser on top of a pillow when i want to use it as a 'lap -top' ----that is literally on my lap. LOL!!! im a mac user for over a year now! and CERTAINLY, I WONT TRADE MY MACBOOK FOR ANY PC OR WHATSOEVER!! lol APPLE ROCKS!!! anyways, heres my question, how do you guys know your macbook's temperature? ive just registered on here and i know im a noob and by the way, ive just learned 'computing' on my own =] (i've other questions later on) peaceMacbook Pro, Mac OS X (10.4.10)
I have been running this little application to keep the fans running at a higher rate and therefore keep the machine a little cooler after intensive processing.

Interesting... All this talk so long ago about the heat coming off the MacBook Pro. Nothing to worry about. Normal they said.... Well, give a year or two and see what begins to happen. My Superdrive died recently and after conversations with Apple they wouldn't look at it, being out of warranty by a month. So I took it to an independent service guy who found that the Superdrive had warped. Now, how does an internal component get warped? Heat. Over a period of time, the heat is a problem. It's like these machines are time bombs ready to go off. What else could this affect in time? I'll say it again. Apple rushed these machines out the door. After paying $3500 for it and being a first generation user. You'd think Apple would want to take care of us beta testers. I will never buy a first generation product from Apple again.MacBook Pro 17", Mac OS X (10.4.10)
