13" MBP hit 90C temp today...

I was running Windows and Crysis Warhead, and beat the whole game in one sitting. (12 hours) The fans were at their maximum speed for basically all that time, and the area above the keyboard was very hot, enough to feel the heat from almost 4 inches away. Is this okay? I propped the two feet of the computer up on some Legos to increase airflow, and snacked on Doritos. However, the computer never shut down and nothing else went wrong other then the excessive fan speeds. Is it okay?

yep sure is,

crysis will give that laptop a beating...my 2.4 ran 80C through that game without a cooling pad...managed to get it below 70 with a cooling pad.

68-70 through crysis...which is not too bad....
the game pushes the macbook pro's to the edge.
 
I just installed SMC Fan control. Upped fans to 4000rpm and its brought my heat readings from..

CPU: 64c > 52c
GPU Diode: 74C > 61C
:D
 
I also have the new 13" MBP and I have exactly the same temperatures.

When running google earth the temps lies anywhere from 65-75C varied and while surfing + playing music it's anywhere from 50-65C
 
General consensus: These new guys run on the toasty side?

Funny how I originally mentioned my CPU hitting 90C but the next time I tried to replicate this event (to see if my fans would kick in) the fans came in full force around 80 and would not let the CPU climb past about 75C.


Weird huh? Only let it spike to 90C that one time...I guess it isn't that big of a deal if it cools off quickly and doesn't do it too many times in the future. I just wish the SMC? would act a little more consistently about when it chooses to kick on the fan and stuff. Oh well, I have Apple Care for 3 years and the only thing that ever sent temps high is the video chatting..I don't do anything else extensive enough to spike temps.
 
The fan controller seems to be on a bit of delay, probably to stop fan pumping for brief temp spikes. It will go back down. Don't worry about it.
 
just spend the last 15min watching videos on efukt.com while having msn messenger and microsoft word running and the mbp hit 85C...
I have 10.5.7 installed with all the newest updates.

since I got it 4 days ago I have never heard the fans kick in at all.

This is on the 2.26ghz low end model of the 13" mbp

anything above 70c is degrading the life of the silicon,

someone should check the thermal paste on there 13" mbp...:p

Arguably anything over 20C degrades the life of the silicon. Laptop chips are designed to be able to take quite a bit more than 70C. Like I said before, Intel's thermal specification for mobile Core 2 Duos is 105C, while on desktop processors is averages around 70C (depending on the processor, but it's usually something oddly precise, like 71.4C). I agree it's probably not good to get all the way up to 105C, but it isn't degrading the life more than Intel designed. There are other problems when the computer gets that hot, like all the other components on the board getting too hot, but the highest temperatures should be limited to the CPU, the heatsink, and the immediately surrounding area of the board.

When's the last time you ever saw a CPU degrade or fail? Now I don't have much experience with 45nm chips, which have less room for error than larger process chips, but in every other computer I have owned or worked on, the CPU has been by far the most reliable component.

Someone definitely should check the thermal grease on the new 13" MBP. (I would, but I don't have one. If anyone wants to send me one, I'll be happy to check for you, but I'll have to keep it when I'm done :p)

how?

if you have to ask, you wont be able to do it.

its not an easy task and can be dangerous if you do not know what your doing.

requires complete disassembly of the notebook, and removal of the heatsink...but if you want to give it a go pm and i will send you the apple doc's for that model.

MacBook Pros tend to run pretty hot. It's no surprise with what they've packed into the 13" that yours hit that temperature.

Was that hot when the new 13" pro was not a pro? I don't think that adding a firewire bus and a sd card slot justifies temp rising.
 
Mine ran way hotter then usual the first couple of days I had the system on but then it started to cool down. I'm assuming the thermal paste had to set in.

My MBP runs 24/7 on my desktop and started out idling at almost 70c but now idles around 50-55c.

Thermal paste setting in? Is that true?
Click to expand...

Yes. It is normal for thermal paste to take some time to set in. It basically has to melt and let out any tiny air bubbles that might be trapped. After a week it should be 99% set in, as long as you use the computer regularly and put at least a few temperature cycles on it (put it to sleep at night instead of leaving it running).

With all the cost cutting Apple is doing, I wouldn't be surprised if the problem this time was too little thermal paste (a few years ago it was too much).
 
I always heard good things about Macs and their quality..after spending a few days reading on this forum and posting several things myself, it seems that these notebooks are just problem after problem after problem...:(

My laptop is new but works very well despite running fairly warm during intensive things (big news for a machine squeezing desktop power into a much smaller space right?)

Is it possibly because most people that post on a forum usually have something to complain about or point out an issue so you see more things going "wrong" than "right." I guess if I was enjoying my computer a ton, I would not feel the need to jump online and create a thread to tell everyone. I am just dissapointed that a respectable company like Apple has so many issues in their notebooks ranging from screen problems to heat management issues...certainly does not make me feel confident as a consumer but glad that I have Apple Care.
 
Millions of people buy Apple's. Doesn't take hardly any of them to make this forum look like Apple computers are pieces of junk.

I've not had one problem with any Apple I've bought yet, zero maintenance or warranty issues and I've used 5 macs over the course of the last 4 years.

1 Mac Mini
1 iMac
3 Macbooks
0 Problems

Yes, definitely. Most people won't notice that the temperature is too high, except that it gets hot on their laps and the fan doesn't make much noise (and the quiet fan is a good thing). Your average computer user probably doesn't use iStat pro, even if most of the people on this forum do.
