I just downloaded the CPU heat widget from apple.com, and it seems my CPU is running at around 52˚C... seems a little high given my experience with desktops.
Is this within the safe limits for a 12" G4 Powerbook?
Cheers!

That's not too high. Which rev Powerbook and what are you running at the time?

erm... its a A1104 G4 Powebook, running Tiger.
At the time I had a couple of browsers, Dreamweaver and Fireworks running, so I guess thats why it was a little hotter.

That widget isn't as accurate as others I compared it with. Temperature text, for one.

You should download a couple of the other temp monitors, like Temperox and Temperature Monitor. They're more informative and useful.
Temperox will give you the fan speed.
Temperature Monitor will graph the temp over time, namely software usage vs heat over time.
In any case, the best cooling device I've found in the summer time is a small, slow, quiet desk fan that blows across the PB (which is slightly elevated to allow cooling underneath.) A quiet fan will cool both you and the pb.

I mean which rev:
rev A: 867 MHz
rev B: 1 GHz
rev C: 1.33 GHz
rev D: 1.5 GHz
Rev A and B tended to get hotter.

If my rev D powerbook runs at better performance and 100 percent cpu for a while (10-15 minutes or so) it will go to around 61 degrees C. Usually happens when I'm playing Diablo 2 or something. I just set it to better energy savings even while plugged in and it runs about 10 degrees cooler with no noticeable slowdown for the things I do.
