... Well I havent tried myself given the fact I own neither, but I find it highly unlikely. EDIT: After doing some research (google), it seems more than one person is indeed experiencing problems with it. If your xbox is under warranty, give it a go. If it isnt, then ring Microsoft and ask there. If they say it wont cause a problem, and it does, then they should repair it.
Mine's been working fine. Ah ****. There goes that then. But seriously, it woks fine, I think a lot of the confusion come with the fact that many people with an Arcade have it in a poorly vented area.
