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!
