You're just hurting yourself like that.
I myself am not about to let RROD make me paranoid. As soon as it gets fixed im going back to playing my 360 just as much as I was.
Besides, I read this article somewhere that talked about how the amount you play your 360 really doesn't make that much of a difference. You could not use it for 6 months then turn it on one day and it has RROD.
