I have a newish MBP 15" : it runs VERY hot sometimes and not others. For instance, if I just sit and browse the web and such its warm but not noticably. If I chat with iChat video it get real hot. If I use iDVD its fine but if I watch a WMV file with Flip4Mac it gets hot. Is this a processor load issue? What am I doing wrong? I put all the hardware info I think is relevant in this post.
