I have recently been saving my games to the hard drive. I have found that the unit not only runs cooler but also quieter and faster (obviously to quicker loading times).

I have looked at a few of those intercooler units and found one by a company called "HIVE" at JB's that seemed to be quite reasonable (only because the other one i saw left your console in the vertical position which i just dont trust). Then again if something is gonna drain power from my console then i am not interested.
