Hi Gix
I bought one for my 360, when I had my white model as people were saying that it would keep it cool and stop the red ring of death.
But after 3 months the fans (3 of them in a unit) started to run noisey and soon were louder than the internal fan, so took the unit back and complained, the guy admitted when I took it back that they were crap and said they had had a lot of returns for the same problem. anyway got a full refund, and have not bothered to get another unit, I just make sure my Elite has got plenty of breathing space.
