The RROD is caused by the heatsink overheating, causing the motherboard to melt, bend and snap. Something like that.
My launch unit never had something like that, because i only played for 3 hours max. Also, don't get an intercooler that plugs in the back. Get one that plugs onto the bottom, vertical position. Why? because if it plugs into the back, it is blowing hot air back into the unit.
Plus, there are new 360 units coming out with new heatsinks and chipsets, which will not only prevent overheating, but will stop the 360 from making so much noise.
LOL COCKS.
