Is this freggin normal?

Any type of video, when I go on video chat with iChat they go off.. when I run photoshop, ok I understand, but for damn video chat on iChat... gets super annoying.

could there be something wrong here?

And another thing, the computer is always hot at the bottom...CPU is at around 55 degrees, airport is always at 70

Those temps are normal.
 
Ever since I've got my macbook, my fan has never been so active after i've updated to 10.5.5. Yet I'm not even running heavy, checked activity monitor and nothing seems out of place.

It seems to occur everytime I start using my macbook, when I restart, or turn it on back from sleep or just start the damn thing. It would run up to a good 10 minutes at 5000rpm plus. Then again, the only application that starts automatically upon login is Quicksilver...

Any ideas peeps? Seeing that I've never had this problem before could someone guide me to find out how this happens? and if anyone else has the same problem after the 10.5.5 update?
 
The best thing to do is to use a widget or menu monitor (iStat nano or something similar) and check which applications make the fans run. In my experience with my 10.5.5 MacBook, applications that make the fan run are:
- Video encoding (expected)
- heavy photoshop
- Skype video chats
- iChat video chats
- Photobooth video
- Flash inside Safari
- iTunes rip

I asked my buddy who has 10.4, and he said that his fans don't go off (2.16 white macbook).

My cousin has a new MBP, and his fans don't go off...

My old MB's fans went off quite frequently. The MBP fans don't because they have a bigger heatsink design and they use the entire case as a giant heatsink, so fans don't need to spin up as fast.
