Does 10.3.9 resurrect the iBook CPU fan?

Mac OS X 10.3.9

This was a very, very good upgrade for me thus far. The .7 and .8 upgrades for me went from bad to worse. Notably in networking, sharing printers, Finder weirdness, among other things. All of that is now fixed! and what's more important is a noise that I heard that I hadn't heard since .6 update ... the CPU cooling fan...IT'S ALIVE!!!!!!

I thought for a few months that my iBook was turned into a convection-cooled device (as the infamous Cube) since the CPU fan never went off. Ever since I upgraded to .9 it's all (the CPU fan included) running again.

Ok, if this is true then I'll upgrade. I too have noticed how quiet my iBook fanhas been for a while. Quiet is good, but hot is not so great.
