By the way, does anyone know if the fan is before or after the HDD? I.e. is it blowing air onto the drive or does it draw air past the HDD? From the looks of things my guess is that the fan draws air from the outside, making it pass all internals before leaving thru louvres (and keyboard?).
I don't think the HDD is hit with any airflow from the fan. Basically, air goes in the intake at the bottom, circulates over the CPU and exits from the exhaust on the right side of the system. The chips by the touchpad and the HDD don't seem to be hit with any of this airflow, hence why the touchpad area gets so warm.
One guy on NotebookReview seems to have improved the situation a bit by cutting off a piece of fan shroud so that airflow from the fan also circulates over the chips by the touchpad. Maybe that's worth a try if you don't mind voiding your warranty. Mine is already over so I might give it a shot.
