The problem was
M$ used lead-less solder on gpu/cpu to keep the environmentalist happy
but
with the temp they had the console running the expansion (when hot) and contraction (when cold) was to great of a difference and the solder joint would,in time get a cold solder joint.
the best thing we could do to slow that down was to make the console run as cool as we could.
to reduce the temperature difference between high and low.
it was not a permanent fix but it would help a console lost a little longer before it RROD
