I had an xbox 360 that would always overheat and red ring itself. Eventually I realized the window fan I owned had almost the same curve angle as the 360 case.

I had an xbox 360 that would always overheat and red ring itself. Eventually I realized the window fan I owned had almost the same curve angle as the 360 case. I built a little stand out of some books to hold it flat upright with the air blowing straight up, with the xbox laid horizontally on top of it. Air was just dumping through the vents in the case and that xbox never red ringed again. Wasn't designed for it but it worked better than the manufactured solution evidently.
