Desktop Icons & Fan Questions

[Forrest Hill]

Two questions:

I have an OSX+OS9 Titanium PB 1GB.  I use OSX 10.2.8.  The fan runs
virtually all the time, even when I am only reading emails or doing
wordprocessing.  Though it is relatively quiet, the constant fan noise is
disturbing.  If I update to OSX 10.3, will the update possibly reduce the
fan frequency?

Also, regarding OSX 10.3, I notice that the desktop icons, when highlighted,
show a large, square halo.  I think it distracts from the clean, elegant
lines of the OSX desktop icons.  Is there any way to turn off those
unsightly halos, or are they there permanently and for a purpose?
