To switch from modem to dsl is all about good things, first one I toke note was ... heat!
Previously my 17" PB rev.A was really hot over the 'esc', 'F1', 'F2' keys... actually having the modem sleeping for a long time, the PowerBook is not that heat. So, is the modem really placed there (or nearly)?
I can not think about another reason to that decrease of temperature
