Atleast I'm not alone

PC Authority's article have began to get attention. I found from Gizmodo's comments many other struggling with overheating problem. Core i7 MacBook Pro Could Make Water Boil

"I'm really not surprised as of just yesterday I got my 2.53GHz Core2Duo MBP up to 205°F or around 96°C while touring around lower manhattan in Google Earth with 3D buildings and all." -RubberShoes

"my spring 2008 15" mbp on a bad day will run up to nearly 110C on the processor." -Mike Karthäuser

"I just ran Cinebench on my two week old i7 MacBook Pro 15" with fairly similar results to the PCAuthority test. On the OpenGL test, the CPU hit 80 degrees C with fans running at minimum (~2000rpm). The CPU test had the CPU temp peaking at 100 degrees C before the fans kicked in to ~4000rpm and brought the temp down to about 95 degrees C." -StoopaTroopa

"My 17" mbp (1st gen with the internal battery) regularly gets to 101-104 degrees Celsius, especially when running flash videos.

Talked to apple store, they said its all cool because the "computer will just shut off if its actually too hot" :-|" -Mat Dwyer

I sure hope that this will collect so much publicity that Apple is forced to act and admit their mistake.

Still no answer from the engineers

Today I got mail from Apple and they were sorry that I have not yet received answer from them as they have not heard anything from the engineering department.

Why do I have a feeling that there are few sweating fellas in the engineering department thinking "how could we have missed this?!"

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.

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.

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!
