Purchased an Xbox 360 E the other day, always been PS, but something new to mod, and though it was time to post up my handywork. I always aim for a stealth mod, so that it still looks standard but operates quieter, cooler and hopefully more reliable. As with any mods, i'm not responsible if you try and damage something, and electricity bites. Fired it up, and after 5 mins noticed that the power brick was pretty warm, and the heat out of the xbox was pretty hot, this was without actually playing anything. Also, there was a rattle in the power brick, time to investigate. Remove the plugs under the feet by using a screw to grip and pop them out. Open it up to find a fan screw rattling around, great for short circuits, but im guessing the fan may have been changed. Give it a good clean and figure out how the cooling works. It seems that the air comes in via a chamber, through the fan, pushed through the brick housing, then out the exit chamber, the chambers are to reduce noise and channel the air im guessing. Now the ducts come very close to the ends, with the exit chamber plate having a baffle, and the inlet slots have 2 small openings, while the exit has many more. The aim is to remove restrictions to let the air flow.
