No. That is quite normal.
I used to be fanatical about fan noise when my 12" Powerbook and I
worked alone in a very quiet room. I solved the problem by propping up
the back of the machine with a 'bruise bag' from the freezer. The
'bruise bag" was a flat plastic bag as long as the PB and about 10cm
wide. It was filled with ethylene glycol gel and normally used for
treating s****ts injuries. I'd cycle the bruise bags through the freezer
every couple of hours.
That would keep the little thing quiet, even when rendering video for
hours.

Propping the back up with a pencil or similar delays the fans starting
a little longer. I'm currently using a couple of CF card boxes.

I used ThermographX but I think it is not compatible with OSX 10.5
The graphs were good and it showed disk and graphics temperatures as
well. It told me when to change the bruise bags.
These days, the gentle hum from the Mac Pro under my desk almost drowns
out the PB fan noise and I drown the lot out with classical music and
noise cancelling headphones. Not great for production, because I keep
stopping to listen to the music. So sometimes I live with the noise to
get work out the door.
