I have installed bitcoin about 36h ago on Ubuntu 10.10. It uses the whole CPU power, quickly overheating my system.

My CPU is a Phenom II 720 tricore black edition, and I am getting some overheating with some other program, since it is 40 Cº outside. (Antipodean summer)

The client has ben generating with one core only for the whole time, but I don't see the first bitcoin yet, is this normal?

Thanks

PS: I have version 0.3.17, I downloaded the binaries, not SVN.
