I have the exact same MacBook configuration. I haven’t noticed heat issues. It doesn’t seem to get any louder or hotter but I have noticed it takes longer to boot up.

This used to happen to me with my Macbook CD and Tiger. These bad-boys do get warm.

Another datapoint: I installed Leopard on my 1.66Ghz Mini and went to do a backup for the first time. Came back and the unit was dead, Apple Genius confirmed that the motherboard needed to be replaced. 3 weeks out of warrantee. :(

Make sure safari or firefox isn’t running in rosetta (get info -> open using rosetta).

Had this problem too, it was a combination rosetta and the shockwave plugin.

This is normal. I have the same laptop with 2GB of ram and it does the same thing. If you watch flash video usually after 30 seconds the fans go full speed. it is very annoying as almost all video on the web is flash. I have tried that latest flash updates and it made no difference. It did it for me in Tiger also. From what I gather, it may be because of the lack of a dedicated video card. When I said it was normal above I meant it happens to us all. I do not think it SHOULD be normal.

ive had that problem not just with youtube videos… but ANY flash videos on my first version macbook C2D 1gb ram 80 gb hard drive… but i had this problem even with Tiger!!! and now its a little worse with a leopard upgrade

My MacBook Pro gets really hot when running YouTube/flash videos. Did the same in Tiger - gets as hot as mid 70-degrees Celcius before fans kick on though.

This used to happen to my 2ghz 2gb ram macbook. Some said it was caused by Spotlight indexing everything. It ended up returning normal for me when I updated a printer driver. I’m not sure if it was actually the culprit, but after the restart, my computer was back to normal.
