I read something somewhere that the fan is different for Core Solo than Core Duo. Is there any truth to that? I don't remember where and when I read it but it stuck in my head and I wanna know before I do anything. Core Solo with 512 MB is not exactly a monster and I kind of have time to fall asleep sometimes while running a few apps. So I figured a Core Duo and 2 GB RAM would speed things up a bit.
