    Hey, just noticed that several people on these forums have tried to suck hot air from their exhaust vents. I got pretty interested since I would still like to get as much additional cooling as possible. But then ive also heard other opinions such as damaging your fan, not effect, etc, etc.

    Can anyone who actually tried this method, post your review here for everyone to enjoy?

    What are some thoughts on how this might work effectively?

    Reviews of these devices have generally said that they do more bad than good. It had been discussed quite a few times on these forums as well. They end up blocking the exhaust vent as the air coming out of the exhaust has a higher velocity versus the velocity the exterior "fan/cooler/accelerator/whatever you would like to call it" could move the air at.

    I personally think if you are looking for more cooling that way you are better to apply AS5 if you already have a cooling pad (which I know you do)

    As far as damage goes using an exhaust booster shouldn't do any more damage than a cooling pad would, unless it is incredibly high velocity (or low) or obstructs the movement of the fan.

    Its better to increase the intake flow

    Sucking exhaust out isnt effective.

    I don't see any reason at all for more cooling. The notebook should cool itself.

    Or do you have a M@c Bo0k? :confused:

    The only real way it’s going to help is if you can significantly increase the amount of air being removed. This means that you need to create an actual low pressure area outside the vent; if you don't then you have just created a blockage or done nothing. Also in theory if you create a low pressure area then you can control airflow and carry the hot air a good distance away, improving overall cooling.

    This basically means creating a vacuum (and something of a decent seal) - not something $2 fans can do. Also since most people’s idea of a vacuum is the cleaning kind, you could easily over-spin your fans damaging them.

    Could the idea work? Yes. Is it all that cost effective and practical? No.
