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?

Macbook Pro fans dont follow cpu temperature

I've now come to a conclusion that CPU temperature has nothing to do with the fan speed in Unibody MacBook.

Right now I'm just transferring some data over LAN to my external FireWire hard drive and fans keep spinning constant 6200 rpm even when CPU is only 60°C (according to iStat)

Lan event ahead

There is a small lan event upcoming and I would like to be able to play whole weekend without worrying that my computer melts, crashes or lowers it CPU frequency during intensive gaming.

Here are few programs I was planning to give a try.

Mac/SMC Fan Control for Windows
Input Remapper 1.0.04

If you have any experience either one of these programs or if you know if I'm going to face any problems setting fans to spin at full speed all time, you could give me a hint by commenting this post or sending me a mail at macbookprostory at sci.fi
Thank you.

4SNS/1/40000000: TNOP-76.375

I tried Apple Hardware Test to see what kind of test program it is. I was told by the service point that it is the only program to determine hardware faults undoubtedly. No other ways are supported by Apple

First thing I noticed was that the fans run ~3000 rpm at minimum during the testing. So it is impossible to notice any fan speed related issues with Apple Hardware Test.

Second thing that I noticed was the error code "4SNS/1/40000000: TNOP-76.375"
I have no idea what it means and by Googling it or parts of it does not give any more info.

I tried running the hardware test again and it passed successfully. Well who would have guessed that the program itself is a bit sloppy. And we're talking about the program which Apple uses to determine if computer is fully functional.

I'll call tomorrow the service point if they have more info what this error code could mean.

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.

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)
