Hi, I just joined here after seeing someone else's post about this and wondered if anyone knows why this is? Hehe when I had the logic board replaced they also replaced the cdrom drive and put in a combo drive (guess they didn't have any more plain cdrom drives). So I'm not too upset about the fan thing, just hope it's not a biggie. "Egun On, Lagunak!!" (Basque For "G'day, Mates") Pete
