overheating

I don't know why.

After I installed ubuntu 12.10 (a few months ago) my notebook always have overheating.

I don't had reported this before because I don't knew the ubuntu-bug command.

I have a dell vostro 3500 with a nvidia. You have my log information there.

Anything that I may help, please, contact me.

Thank you for you amazing work.
