Love the Drake

Dumb idea or great idea?

I have a bad feeling about this new product called RACHAL (Reduce Annoying Computer Heat And Loudness). It's supposed to cool your room by sending the exhaust from your PC and send it directly into your wall.

But, the exhaust just goes into a wall so I would think this would eventually cause some ventilation problems for the computer with hot air buildup. In fact, their FAQ addresses it:

How long was the product tested for?

The product was tested with about 20 different computer chassis configurations running for 3 months. The only difference we saw between the systems was the temperature. Since the ventilation system restricts airflow somewhat, we noticed some systems had increased chassis temperatures due to poor design.

Is that poor design of the chassis or RACHAL?
