me too have modified my xbox in hope to prolong it's life span. what i did is very simple modification
anyone can do it, and i believe it is really effective but have to sacrifice on how the xbox
would look like...

1. diassemble the xbox

2. put some cardboard or thick paper on top of the gpu heatsink ( i used calendar paper). this can
improve the air flow, most people believed that. i used wire insulating tape to attach the card board
on the "air flow tunnel" - plastik yang warna putih tu.

3. put some tape on cpu heatsing also to minimize any air flow leak between heatsink and the tunnel.

4. cut the original fan wire and connect it to 12v source. i used a cheap ac-dc adapter, cost me rm12.

5. don't bother to assemble the box, just leave like that and put a table fan directly on the right side of your
box when playing games.

6. the result: after playing 6 or 8 hours straight in a-cond room( gears of war, bioshock, assasin creed), the
cpu heatsink as cold as the room temparature, gpu heatsink suam-suam( a bit warm), and the dvd disc
as cold as the room tempature just like before you put it in the box and played it.

i did this modification on my box two weeks after i bought it because the shop where i bought it
only give 1 month warranty, and the warranty does not cover the 3rrod........its been going strong
now for 4 months....i hope it will last at least after i finished play DMC 4.

....i also cut the rf/dust shield on the back of the fan to further improve air flow

hahahah....i don't think there are any formula that can prevent the inevitable 3ROD....

i think the 3rod is cause by many other factor beside overheating, like manufacturing process or design defect
for the early batch of 360.

i say this cause i have made my xbox 2rod twice before. since i connect the original fan to external power supply,
i need to manually switch on the adapter, sometime i forgot to swith it on.

i played some game for about 3 minutes, and there you go, xbox automatically shut down and 2 red led blinking.
switch on the fan, reboot the box and everything goes back to normal. this kind of event shows that the xbox temperature
sensor is indeed working just fine and it knows how to shut down the box if overheating.

but as we all aware most xbox just go straight to 3rod, not 2rod which is the indicator of overheating.
sooner or later, 3rod is on the way. the only solution is buy everything original from Djinn, at least
when 3rod hits can change on the spot for a new one.
