Apple's opinion is that my computer is fully functional
I sent a screenshot to Apple where my CPU, GPU and Chipset is near and above 100°C (according to HWMonitor)
I was in a belief that all this "your computer is ok" crap is only because they do not believe that my computer really overheats. So I decided to try once more and show them yet another screenshot.
This is direct translation from email I got from Apple technical customer service.
"I apologize that you feel that there is a lack of faith. I'm am sorry to infortm that screenshots will not change Apple's opinion in this case. Apple's opinion is that your computer is fully functional. We have inspected your computer as much as possible and all possibly faulty parts have been replaced at least once and the situation have not changed. Unfortunately I must inform that from the technical point of view this case is finished.
I hope that the answer is clear enough. I'm sorry that we can't proceed any more."
How should I understand the "from the technical point of view" So there is still hope i.e. from legal view?
Someone from (non technical) customer service should have called me last friday. Still waiting that call. Good thing that I'm used to this waiting. Every time someone from Apple tells me that they will call me back tomorrow it means at least 5 days. Next week means 2-3 weeks.
Next Tuesday I have a meeting with a lawyer. He or she can clarify which laws Apple is now breaking.

Thermal paste flood
Little amount of thermal paste is better than none.
But too much is definitely worse than little.
The Thermal Paste Reapplication Endeavor
Everybody remember when first Intel CoreDuo MacBook Pro's came out? There were way too much thermal paste and temperatures were "quite high"
Apple should have learn their lesson.
I'm tempted to open my MacBook Pro to check if there is similar problem with excessive thermal paste. But Apple have promised to check whats wrong with my computer so I don't peel this apple... yet.

Apple! Where's your spine?
I was told to take my laptop to a service.
Apple now suspects that the motherboard might be faulty. I gave them the error code I received some time a go when i ran the hardware test. "4SNS/1/40000000: TNOP-76.375"
The "TNOP" part here means that it has something to do with the temperature sensor.
Too bad that it has nothing to do with the ineffective cooling. Seems more like a excuse rather than a solution.
Pay attention to number 3. Maybe somewhere next Wednesday magically every Apple laptop might start working when they fix my possibly faulty temperature sensor.

- If it would be faulty temperature sensor why the computer would shut down due to overheating even the fans spinning full speed? (ok... this one is possible with wild imagination)
- Why would the computer run constantly at lower clock speed if it would not be too hot?
- Why would my computers broken temperature sensor affect EVERY UNIBODY LAPTOP IN THE WORLD!?

Sleep Notification occurred.
I was told to run "Capture Data.app" when I have reproduced the shutdown due to overheating -issue. I've been told to run this app once before and then I did not pay any attention what data the program collected.
Today I've finally found time to play along with Apple and it did not took long for the machine to overheat and suspend. Then I run the Capture Data application and this time I checked every little file the application collected and was suggesting me to send to Apple.
Here are just few things I've found:
This is only what Apple would have needed:
2010-05-05 11:54:43 EEST - T[0x00007FFF70C30BE0] - Sleep Notification occurred.
Too bad I was again too hasty and send the whole thing to Apple before thinking. During last hour I have also changed all my passwords.

Here are just few things I've found:
- All users passwords hash, account creation dates, user images. Also the deleted accounts were included.
- All files I've opened since last week. (file names and full file path) Including every movie I've watched, work files written and school projects opened.
- Nearly all programs I've started during last 5 days
- Every file which I've downloaded since last week. (With Firefox, transmission, wget... you name it)

Even the full fan speed is not enough
Good thing I did not attend that LAN event I mentioned earlier.
I've tried to play Just Cause 2 demo but my MacBook Pro sets itself to suspend after I've played about 20 minutes. HWMonitor told me that CPU was 111°C and NVIDIA 9600M GT 103°C just before screen went black.
Only way to prevent this happening is to raise the computer few centimeters from the table and add external fan to blow cool air towards the enclosure. Sounds really pro solution for a Pro laptop?
CPU throttling sure is annoying but computer constantly shutting down due to overheating is more frustrating than lowered CPU frequency.
I've called Apple to inform this new symptom. Let's see if this is a feature too?

Fans follow only the enclosure temperature?
I installed Snow Leopard only to notice that nothing changed.
Could it be possible that fans try to keep only the enclosure cool? No matter how hot the CPU is fans will will not speed up until the enclosure gets too hot?
See for yourself.
In the first picture I have run Seti@Home with CPU and Einstein@Home with GPU (NVIDIA 9600M GT) about one hour and temperatures have settled down.
Before taking second picture I let the computer sleep overnight to make sure it was completely at room temperature and the I launched the same applications (as in the 1st picture) and waited until CPU reaches ~110°C .
As you can see most temperatures are higher in the second picture even though computer have been under stress less than 3 minutes. Only enclosure temperatures are higher.
This is so frustrating. I'd better call consumer dispute board to ask if they have moved forward with my case.

60 minutes of free music from Apple
Today I called the consumer disputer board to check what's the situation with my case.
I was quickly forwarded to a guy who apologized for this has took so long. He said that he have had problems contacting Apple. We discussed a while and he said that they have several other cases with faulty Apple products and Apple refusing to do anything.
He gave me a number where I could call to contact Apple and he also promised to do his best to conclude this case as soon as possible.
I called the number I was given and was soon answered only to be put on hold for 10 minutes (to check things and ask more info - they said). Then I was forwarded to another department. I had to wait another 10 or 15 minutes before "another department" answered. I was told that they stand behind their previous judgment from last December where this overheating is not a fault at all.
"It is a feature"
Now I have to admit that I lost my temper for a second and quickly replied "How not-working could be a feature?" The help desk stood in his script and said only that my computer is not broken. He reminded me of Apple engineers statement how this type of behavior is normal and within the specs. "Computer is not overheating unless it crashes or shuts itself down"
I demanded money back from my computer and I was told to wait "few minutes" so he checks Apple Store department what they have to say. 20 minutes later I heard briefly that I should have returned my machine within 2 weeks from purchase, money back is no option any more unless I want to wait little more so he calls the legal department. 10 minutes of waiting music did not help the situation and I was given only one option. To take my computer to a service point and if they finds a clear fault in this I am justified to a repair. BUT! if they don't find anything I'm obligated to pay for the service visit as the warranty had ended 2 weeks a go.
Customer service - a big joke!

Know your consumer rights
I've now contacted the consumer dispute board which took my case into their consideration.
Actually the board received my letter January 27th and I hope to get some answers soon.
I hope that they understand that this computer is truly a faulty and advise Apple to either give me my money back or to swap it to a new one. I'd prefer the money back as I've found that nearly every one of MacBook Pro's are affected of this lazy fan issue.
http://discussions.apple.com/thread.jspa?messageID=10767250�
If you search hard enough you might find few other threads describing this same overheating which Apple have missed and threads did not get deleted. (yes, I believe that they delete threads mocking Apple)

More direct approach
This time I've had enough. Exactly one year a go I fought with my previous MBP and Apple needed 3 service visits before they accepted to change my computer to a new one.
Now when I called Apple I knew already that by swapping this machine to a new one might not help at all. All I want is to them to realize that I have now in my hands a faulty computer and they should do whatever is to be done to fix it.
First calls was like teaching quantum physics to a dog. It was so hard to Apple people (okay, people whom I speak with who worked at Apple phone service) to understand that it could no possibly be a software fault. Once I made mistake and mentioned that even running 2 virtual machines simultaneously is enough to overheat CPU to 100+°C. Then I had to answer next five minutes to questions "have you updated your VMWare?" "some software consume more CPU time when not updated"
I bet these people would rather open windows on a car when cold than turn down the AC.
Then I found the secret words "can you put trough to the different department" then I was able to talk with people who have more logical approach to this problem. After serious of consideration of this problem I was stunned. I thought that the joke of "it is not a defect it is a feature" was only a joke... Big news it's true... not the part "it is a feature" but the part where it is not anymore a funny joke. When I've told for the 10th time that this overheating issue occurs every single time and not only on OS X but also with Windows I was told to visit the authorized service point once more.
This time I did not left my computer there as I hear the magic words (this could be second magic phrase already?) "Our hand are tied we can only do what we're told to do" So there were no point of swapping the motherboard any more. I had opportunity to show the people at the service how bad the situation is and quickly we booted my MacBook Pro from external clean OS X 10.6.x install and I was able to get CPU to 105°C. I was only told that these machines are not meant to be used like that. No joke here either.
I called Apple again and tell them that this overheating thing is real and asked if they are planning to do anything to fix it. I was told to run certain app that collects data while I reproduce the fault. Yes the app collected data alright. Data from sending fax, file system usage and last but not least it collected network usage. I was not amused.
I was questioned (by mail) for the seventh time whether this overheating occurs only when using certain programs (like I have not told that to them clearly enough six times before?) and being suggested that maybe upgrading to Snow Leopard could help. (I should pay more to be able to use my computer? And I've already proven that Snow Leopard does not fix this issue and. Even if it would fix overheating temporarily I would not settle with that. Permanent fix should be updated firmware which would follow along to Windows too)
Today 18.12.2009 I got final call from Apple and message was this:
"This "flaw" you described is normal thing and we've discussed with engineers and they've came to a decision that by swapping your computer to a new one would not help in this manner."
I'm speechless.
Please Apple fix this lazy fan issue so I can use every megahertz that I've paid for.

The era of Unibody
I don't know whether last blog entry ended dramatically enough.
There are no words to describe how my thrill turned to disappointment.
I did not like the Glossy screen. I definitely did not like the loose hinges, but most of all...
I did not like my new MacBook Pro's CPU overheating to 110°C and therefore CPU dropping to 1,6GHz
15 minutes after hearing the "wall-e chime" i typed "yes > /dev/null" in two separate terminal windows just to check how quiet this new Unibody computer was. Indeed it was quiet... it was really quiet... a bit too quiet?
Soon after installing temperature and fan speed monitor software if found out why this Unibody seemed so quiet compared to my 1st MacBook Pro which fans were at 4500 - 5000rpm and cpu temperature was at 85°C at full load. This Unibody MacBook Pro's fans never speed up above 2000rpm. When I had enough courage I launched again two yes -processes and this time I did not quit them... I watched CPU squirming at 110°C for ~5 minutes and eventually fans started slowly speeding up untill CPU temperature was dropped to 95°C.
I even installed the supplied OS X Leopard twice to make sure that it is not software related problem. I also installed Windows XP to check and yes. Same overheating problem (actually I should call this lazy fan problem) occurred there too. I tried gaming but first 15 minutes was like a watching dia presentation as the CPU was constantly switching between 2800MHz and 1600MHz.
I was angry, not again a faulty computer. Well this time the flaw is so obvious so I have nothing to worry about. Maybe one week without computer and then I could finally have a computer whereto I can trust in every situation.
Did I mention before "boy how wrong I was" ?
I made one big mistake. I Google'd "Unibody overheat" and found several other Unibody owners struggling with this fan issue.
I made my assumptions that this is a flaw that concerns all Unibody laptops. Therefore i thought that Apple would make a Firmware update to make fans wake up earlier. And because an fix is already on its way it is pointless to take my new machine to a repair.
I prolonged the inevitable too long. Finally I had to visit the same service point and I asked whether they know what to do with this type overheating. And sure they did have an solution...
