Main problem was fixed.
Originally The GPU gets too hot and connection to PCB cracks then system is dead.
The Original units had a simple heatsink and it was not enough to cool the GPU properly.
New X360 units have a heatpipe and radiator on the GPU (same as the PS3 has on it's GPU and CPU) so it's much better.
The CPU on X360 is still on a simple heatsink though fortunatly most current games dont use 100% cpu but if they did it may also cause RROD problems in the future.
Overall the PS3 has the most elegant cooling system of any console with it's heatpipes and single low speed 120mm cooling fan It can pump heat out very effectivly and is designed to last. It's cooling system is the best by far.
X360 has 2 small high speed (noise generator) fans if either one fails the unit will probably RROD.
Wii probably does not even have a fan it generates under 20 watts of heat. ?
PS3 number 1 fan
