Xbox RROD

About 3 months go I fixed my 360s problem of RROD (Red Rings of Death) problem. I had the problem again, and have realized that the case is keeping all the heat inside, which making it impossible for it to cool. I upgraded the fan to the 12V and removed the top covering permanently. I have no intentions of putting it back on. It is running 100x more cooler now with the 12V fan and the case open.
