Temperature and Mac speeds...whoa!
I was biking outside in the cold with my ibook in my bag and when I got back home the book was really cold and felt like it was frozen. I opened it up and...
everything was quite noticeably faster, especially window resizing, which for my iChat window was smooth (usually it's quite jagged)
I was so surprised. After half an hour the speed went back to normal.
This was a purely qualitative experience but I'd like to test just how much faster it is quantitatively.
I'd heard stories of temperature affecting processor speeds before but never realised there is actual perceived difference
Anyone have any ideas about this or have experienced this?

haha, I did the same, but it has to be colder than that to work.
Why am I hearing Rod Serlings voice??? I'm getting creeped out now...

Does it really work that way ? I mean does the iBook have built-in control to increase its performance when the processor is cold enough. I know (well pretty surely) that it has the inverse. Or am I way off ?
No,
the way it works is that at lower temperatures semi conduction is more efficient.
it is true for every machine, I just for the first time experienced it.
I always thought it would increase in speed but nothing you can perceive, but I'm very positive it was faster.
It was like, wow!
the iBook also has to be chilled to the core, so to speak. thus, it has to be outside for not too short.
does anyone have scientific info to add?

I have an interesting, slightly related bit of info to add! The iPod has an operating temperature range from 32 degrees to 95 degrees.

wow that is so intresting I will add to it.. the iPod has a storage temperature range of -4° to 113° F
Wait.. don't forget relative humidity: 5% to 95% noncondensing

A ridiculous anecdote.
yup

sounds logical and I would certainly not put my ibook in the refrigerator.
I think it depends on the relative humidity. My room is only about 20% humidity so it's really dry.
Case in point: last winter I kept using my iPod outside during a Montreal winter, putting it in the pocket of my GoreTex shell (meaning no insulation). How cold was it outside? Around -30 Celsius with wind chill. This caused me to have very short battery life at the time, and my hard drive locked up on at least one occasion causing a total crash.
