There has been a rumor that the Microsoft intercooler wrecks your xBox 360. Well, it's true.
How? The intercooler runs on the same power supply as your xbox does so it runs your power box at double the stress, which will burn it out and make your xbox 360 get the ring of doom. The only thng that the inter cooler does good is cool your xbox a little, but is it worh the risk. So don't buy this piece of junk, cause it's not worth it!
So don't worry about your xBox 360 heating up because it wont wreck unless you play 48 hrs without stop.
