This may be a silly question, but which way is the fan supposed to be blowing on the top of the XP-90? I can make an arguement for it either way:
1) down into the HS: more airflow through the central parts of the HS, but blows hot air over the motherboard
2) up away from the HS: less airflow through the center of the HS, but the hot air is being pushed away from the other components and the cooler air is being drawn in from the sides.
I'm probably missing something but there didn't seem to be anything in the documentation that came with the XP-90.
