    The back of the dv9000 has some slits for airflow, and there are also slits on the bottom of the unit. Because the airflow is so weak, I can't detect by feel which way the air is actually flowing.

    Does air enter from the bottom and get exhausted out the back? Or Does air enter from the back and get exhausted out the bottom?

    My as-yet-to-be-made cooler's fans will be mounted below the slits on the bottom of the notebook. Therefore, it's important to know if the fans should blow air onto the bottom of the notebook or if they should pull air away from the bottom of the notebook. This is crucial because if the cooler's fans are installed blowing air in the wrong direction, they could actually force hot air back into the notebook!

    Unfortunately, I can't judge the proper direction of fans by observing commercially-made laptop coolers, since I've seen different models with fans blowing either toward or away from the notebook.

    Intake from the bottom, exhaust out the back.
