Negative Positive
Title: Read the reviews.
Review: I was going to buy the cooler, but then I read the reviews and realized that the reason my XBox was heating up was because I had the side vent right up against my cable modem. Basically I had the vent blocked so the fans weren't blowing out the air. The same thing happens when you put the XBox vertical. The vents are pointed toward the ground, so the air-flow is blocked. They really shouldn't even have those softeneres there and advise people not to stand theirs up or have anything blocking the vents. People have bought the cooler and it has given them problems. That's because it's using the XBox's power, basically taking power away from the XBox. That's how you burn out your system. It definitely is more harmful than everyone thinks. Notice that even the people that are raving about the cooler are saying that they are having the red light problems. Forget the fans and just keep the system laying flat and don't block the side vents.
