Nyko Intercooler ($20). The snap-on device helps lower the internal temperature of your 360 by increasing the air flow with its three fans. By keeping everything cool, the Nyko Intercooler will also help extended the life and reliability of the 360 components (and we all know how hard a 360 is to come by if yours suddenly dies). The device powers on and off automatically with the 360, and works with your 360 displayed in either horizontal or vertical format.
