Macbook running hot

I've got a unibody macbook and am generally pretty happy with it.
However, I've noticed that the bottom gets very hot and the CPU usage hits 100%+ for finder when I've got a PDF open in preview. Preview itself only shows minimal usage but Finder shoots up and down when I open & close the PDFs. Same thing happens with Acrobat Reader when I try it.
Anybody go any pointers?
Ta in advance

The Alu Mac's do tend to get quite hot as they dissipate the heat through the shell. Normally around the vents they can be hot to the touch.
You can always download istat which is a excellent and widely used system monitoring app. It gives you temperature monitors to see how hot it gets and many other features.

My white Macbook can hit close to 80C on occasions, but normal running seems to be about 35-55C range.0 -
For problems on Mac OS X I would check to see if there are updates available from Apple. Then if that doesn't work, I would suggest deleting the application's preference files.
Go to your user folder, then Library > Preferences. Then, drag the following onto your desktop:
com.apple.finder.plist
com.apple.systemuiserver.plist
com.apple.loginwindow.plist
Then restart and see if that fixes anything. If so, you can delete the old preference files from your desktop. If it doesn't work, you can put them back where they were.0 -
I don't quite remember the details as I was sorting out someone else's MacBook but they had a problem with 100% CPU usage causing things to slow to a crawl. I called up some sort of widget in the Dashboard(?) which was a bit like the Windows Task Manager which showed what it was that was using the CPU. It sounds like you may have already checked something like that though?
It turned out to be a driver for a Canon printer which for some reason was using 100%. Everything went back to normal when I uninstalled it from the printer list.0 -
