Pictures of SR MBP high CPU temp due to poor thermal paste application (56k ok)

It should be noted that according to Intel's own specs, the CPU temp should be below 50 degrees C or 35C in order to "sleep", or "deep sleep", respectively. A sufficiently crappy thermal paste application could prevent your CPU from accessing its power saving "deep sleep" feature.

Yet another reason the target temperature set by Apple for the CPU of the MacBook Pro is an important quantity, apart from the maximum possible operating temperature before thermal shutdown as defined by Intel.

Proper MBP paste jobs see CPUs under load operating near 70C. That would seem to be Apple's design. In my opinion, anything else is defective.

Did you even read the document, especially the parts where the type is smaller than everything else? It says all over the place about not being 100% tested, temp varying between 50-100c, based on specific design....

In a perfect, controlled environment I'm sure you get the 70-75c temps, but in the real world, they're going to be higher.
 
Basically, if its under 100C, its fine. Just dont use it on your lap :p

My MacBook runs at around 70C, and thats fine.

Yes. Read what I said about the sleep / deep sleep modes.

EDIT: if you're having trouble being convinced, please go back and look at the original pictures of poor thermal paste application. There isn't much room for argument.

pages 75-76 in the pdf I linked, look it up. After all your posts you haven't given any evidence in support. I give Intel .pdf's and experimental reports from people who've changed their paste jobs, pictures of obviously horrible paste jobs from past and present. It would be so nice if people didn't feel compelled to defend Apple.

You need to learn to read for 2 reasons!

1. "Not 100% tested. These power specifications are determined by characterization of the processor currents
at higher temperatures and extrapolating the values for the temperature indicated."

- In response to your quoted temps

2. My posts have had an intel link in.... so your clearly not reading....

Speaking of learning to read, that footnote (repeated many times in the text, cited as item 2 on page 75), refers to power specifications (wattage), not temperature. If you look at footnotes 7 and 8 on page 75-76, you see that sleep and deep sleep specify a max Tj (junction, or CPU, temperature) of 50 and 35 degrees C, respectively.

If you have a really crappy paste job, your CPU will not reach 35C, even when idle. Hence, it is a problem for Apple to fix.

Seriously people: have you ever built a system of your own? I have. Dozens. Has its thermal paste job ever looked like this?

Mine hasn't. Because I want things to work properly.

Yes, and it's making me go to sleep/deep sleep. All you have provided are generic test results.
 
So chem, you told me i was a fanboy and that this only exist with Apple laptops....

So how do you explain that fact that Dells, Sony's and Acers are all coming from the same factory and same production lines with the same staff?

To be honest i couldn't care less if we were talking Dell or Sony i would be saying the same thing. Think its about time the mods sorted this out.

Well, since you have a picture it must be true.

1. I am not sure of the truth of the statement that (these brands) "are all coming from the same factory and same production lines with the same staff". If you have any evidence of this, I would welcome it.

2. I have not seen any reports of any Santa Rosa based laptops, other than Apple's, running at 90 degrees C or higher under full CPU load. If you have any links to reports of this, I would welcome them.

Does this post even have a point? Are you suggesting that I paid someone off on apple.com's support forums to fake a picture of poor thermal paste application? Do you think that's a good paste job? haha.
 
I think it's time we agree to disagree. There are several of us that are operating above 75c for periods of time and we're not having problems. I think it is safe to say that we are safe up to the 100c mark. Even running at 90c for an extended period of time (meaning a couple of hours) is still not hitting 100c and not in any danger. Let's move on and stop wasting time on this.

I agree, there is no telling some people.

100% agree. Learn to live with your hot laptop, and deal with it. That or get a desktop. Simple as that.
 
basically i don't care how warm my cpu gets, but if it gets hotter than it would have to, the fans will turn faster and make a louder noise which i would really hate.

surfing, email: 40°C
heavy load up to 55°C
fans become noticeable at 47°C
12" 1GHz PB

my dad will receive his mbp this week and i hope it won't get close to 100°C :(

we'll see

i believe we are talking about laptops here, or am i just a n00b and cannot tell the diff in mobos?? how many laptops would chill at 35 degrees when running idol?? not many

Question:
If you can see the paste thru the rear vents, is that a good or bad thing? Should the paste not be visible if it was applied correctly?
I pointed my flashlight thru the vents and can see [excess] paste on all three processing units. I dont see any "spilling over" from this vantage point.
Ona full load, it registers around 85C.

On the side, what is the third processor unit for? I know CPU, GPU, ???

No that doesnt sound right although your temp at full load is ok.

I am guessing the third chip is the chipset.... northbridge chip.

yea thats if your using some SR 1.8ghz thingo. that has ssoooo much power. </sarcasm>

Or the Thinkpad T61... which can have the same CPU as the MBP, runs at less than 70C under load, and is only 1.1" thick. The MBP has other advantages (video, Mac OS X), but c'mon, let's be fair: nothing but good things have been said about the T61's cooling system.

Then buy it but as you say it doesn't have the gpu of the macbook pro
 
Grrargh!

What a shockingly stupid argument!

1) It is pretty clear that a CPU running at anywhere up to 100˚C isn't going to be damaged, or have its life shortened. It can take it, no problems.
2) If the heat isn't exiting as well as it should through the heat sink, then a large portion of it is obviously going somewhere else. A CPU running at 95˚C is not going to be good for other bits of the computer close by.
3) The computer may or may not drop to a lower clock speed to try and avoid getting any hotter, so your computer might not be running as fast as it should.
4) Take it to a bloody Apple Store, and get it checked out. If they are willing to fix it, which I think they quite likely will, then that's the end of that!
