They cannot get the RROD, however, the new vent ports can cause a problem with dust gathering. My last model almost fried itself because of apparent dust buildup (dunno how, I keep the area around it clean) by creating an extra circuit the system had no idea what to do with.
To add, I would look into a $20 intercooler, closes up one of the vents somewhat, but keeps the system cool as a whole.
EDIT - Dang it, thought I hit the edit button. -.-
