i7 = 100 degrees C, unibody too thin?

I love how everyone is just running with this story, yet it relies on ONE particular macbook pro. Anyone with an i7 17" MBP having the same issues?
 
There are about 7 threads already on here discussing this. And their fans were not even over 50% utilization so there was something going on with their unit.
 
With those kinds of temperatures, you are going to cut few years out of the life expectancy.
 
Holy crap.

See, my quad doesn't even hit 60 degrees when I push it. Geez!!

Apple needs to change up its unibody design or get rid of it. Not enough cooling going on in these laptops. At those temps I'd be surprised if the macbooks lasted a year before dying. I don't understand the fascination with super thin laptops. I'd rather take some proper cooling any day.

Story you linked has been pretty well debunked. Don't be so gullible.

The first-gen MBP's regularly hit 100ºc +. I still have mine and it still works fine. Remember this is the temperature of the CPU die and not the case temperature.

You are the one who is gullible dude. The processor is the same if you look closely at the CPUID. CPUID displays them both as i5 since its a new processor and its not in the program yet.

To recap: The MacBook Pro's Core i7 processer never exceeds Intel's thermal spec limit. The MacBook Pro's case gets warm under maximum and abnormal processor stress, up to 3.6° F above normal human body temperature, or 98.6° F. OMG, alert the media!

also apparently the writer doesn't know the difference between Fahrenheit and Celsius lol.
 
That's past the thermal threshold I believe, either way it's not a good thing.

I know from experience the aluminum enclosure passes along lots of heat as well, I'd guess the outside of the machine is getting into the 80s (maybe 90s), if the CPU is reporting 100c temps.

If I used a PBG4 for say, 5 hours straight with medium-intensive work, the machine would get really freaking hot. I can't imagine using an i7 MBP for anything useful lol.
 
Regardless, you think if it was overheating that bad, this forum would be full off people experiencing the exact same symptoms.

But hey, they got a few hits out of everyone today. Gotta love the innernets
 
mine hits about 95-98 doing a "yes > /dev/null" in 4 terminal windows.

The fans do kick on, eventually. Im not worried about it. My advice to others is, quit whining.

And don't use it on your lap unless you want to be sterile

Thermal threshhold is 105 C for the i7 IIRC.
 
A CPU under great load under near-max temps will still last beyond 5+ years my friend ... how many times do you hear of a CPU dying out? CPU temps have actually come down compared to years ago, as the CPU die size shrinks.

actually, i think it's the complete opposite. EVERYBODY has experienced the symptoms, so people take it as working as intended, and don't fuss over it

with my unibody macbook, i have definitely experienced times while stressing the processor that the case was so hot i couldn't keep my hand on it for more than a few seconds at a time

and i know people are going to reply back at me and say their laptop is super low temp, etc. etc., but i don't think most people really use their computers that intensively

The CPU may not die but the solder holding the GPU and everything will eventually crack from all that heat.

And notebooks generally have barely enough airflow anyway. I've seen a quad core Mac Pro running something on all 4 cores and barely break 50 C. Not surprising that a notebook with its processor running full tilt is going to heat up a lot.

Yeap, and even Engadget stated it was a fluke and they had NO problems when they reviewed the laptop.

But I wish there was a mod on here to close the what must be 7 threads on this same subject now.....
 
Maybe everyone who has hit those temps spontaneously combusted while trying to post :eek:

the cpu will auto-shutdown or auto-underclock itself WAY before that happens. take a look at the datasheets on intels sites. they have about 2-3 different trip points that if the procs temp hits them different measures will be taken so that the processor does not get damaged. and it's all hardware based. so this will happen no matter what your software is doing, even if your comp is totally freezed up this will happen.

No issues when I bought it, but I did noticed this upon opening up the machine:

That's just way too much. There was about that much on the heatsink side as well. Feels like the 2006 MacBook Pros all over again.
 
That macbook pro probably had some issues with it.

I've had my i7 17" 2.66GHz model since day one and it runs so cool that I can keep it on my lap without using the usual iLap as I did with the previous generation mbps.

I get around 45c to 60c, I've seen it go to 90c once but thats when I made all 2 cores (4 virtual cores) tax at 100% (from terminal command) and kept it that way for an hour just to stress test lol.

But right now, I have my 17" connected to an external monitor, running 9 spaces, downloading a bunch of stuff, uploading, extracting 10gb+ files, mail opened, ical, vmware fusion running windows xp compiling stuff, and safari opened with 8+ tabs and firefox opened with 4+ tabs and my cpu is right around 50c-51c. It runs very cool and VERY fast!!

As for the folks that want to shout out, pics or it didnt happen!!

There ya go!! The crazier part is that its only using 2% of the CPU!!

What am I looking at? The camera flash makes it hard to see anything beyond that I'm looking at the i7. Is it that pasty looking stuff you are referring to?
