MacBook Pro 2011 Core i7 Quad Core 2.2 GHz freezes when running hot!

I just received my Core i7 2.2 GHz Quad Core 15 inch laptop today. I was eager to put it through its paces. I have been trying to compile/install gcc and watch some HD youtube clips at the same time. As it turns out that's a very bad combo for this laptop. Compiling gcc maxes out all 4 cores and then you add some graphics usage (especially on an external monitor, which kicks in the AMD 6750M chip), the computer overheats. When the CPU Temperature Diode measurement reaches 92 deg C, the computer crashes, every time. I have crashed my new laptop 6 times already this evening, all due to this issue. I kept an eye on my Kill a Watt meter and it pegs near 85 W (battery fully charged). I think a firmwire update to the fan control unit is in definitely needed. The fan is obviously not running aggressively enough. When you have a 45W CPU plus a 30W GPU, plus 13 W of just turning the machine on, then add in WiFi and HDD, you got one hot system. Intel lists a Tjunc of 100 deg C as their temperature limit. Apple needs to figure out either how to gracefully pause while the CPU hit that limits (i.e. not crashing the whole system), or keep their fans running more aggressively when the CPU + GPU activities picks up in a hungry.

::ahem:: Re-applying thermal compound is a modification.


See: http://www.apple.com/support/macbookpro/service/#warranty4


4. What kind of activities will void my warranty?

Apple’s One-Year Limited Warranty for MacBook Pro excludes coverage for damage resulting from a number of events, including accident, liquid spill or submersion, unauthorized service and unauthorized modifications. If damage is outside the scope of warranty coverage, service may be available through a local AASP or an Apple retail store, but all service charges will be your responsibility. In such an event, you will be asked to approve the estimated charges and accept the terms and conditions for service before authorizing the repair. If the repair is performed at an Apple retail store Apple's Repair Terms and Conditions will govern service. Repair service for a MacBook Pro that has experienced catastrophic damage, for example extensive liquid damage or a severe impact that results in the product being disassembled into multiple pieces, is generally not available and not eligible for service.


Why anyone would open their computer to re-apply thermal compound while it has a warranty is beyond me. 😕

That says if you damage or modify. He is NOT modifying anything. As for Damage, if he is not careful he could end up damaging something, but that's on him. Why would anyone do it? Because better thermal paste can lower tempatures 2-3c and apple is known for haphazardly applying thermal paste and using inferrior thermal paste. Btw, there is plenty of case law that prevents apple from voiding a warranty for modifying a product. Car manufacturers have tried doing the same for years. They tried voiding people's warranties for using cool air intake systems, 3rd party air filters, synthetic oils and lubes, etc.. you name it. They have lost in the courts too. People just need to stand up against corporations loike apple and not be taken advantage of; people have rights!!

i did take the risk for 2 reasons, first, to replace the optical drive with a fast ssd, and second to re-apply the paste. i did it quite carefully and am pretty sure i didn't damage anything. it's been running for 1 month now without problem.


of course if i did break anything, i would have to take the responsibility myself.


this is how nasty it was before i re-apply the paste.

That's way to much paste and its actually spilling over. Whoever applied that was not careful at all or just did not know what they were doing. That is painfully obvious.
