I just saw an Antec USB notebook cooler for $10 and was wondering could I just plug that in the 360's USB port and call it a day?

I couldn't bring myself to buying that $25 intercooler and besides that, a notebook can....cool my notebook if I choose to use it that way.

My 360 is in an open space now but I wanna put it in a cabinet. There's no way I'd do it without a cooler.

The heat would go nowhere.
