hi,
I made my mod to avoid the RROD using the following method:
I added the 360 to a notebook base with 2 fans bringing air to the below part of the 360

I added two pc fans behind the 360 to remove out the air:

and one fan on the right to send air inside the case:

All the accessories take power from an external power supply. 12V
The results are great. the 360 is extremely cool, and I never encountered any freeze.
Even when you open the DVD tray, or open the memory card port of the 360 you fell the air moving out.
It is a very cheap, easy and efficiently solution
I think the air recycling is becoming very strong inside the case
Also you avoid open the case, .................... 3 fans blow inside the air and two extra remove.l... try it and you will see
