I'm talking about mine under the bookcase, not next to my 360. So, in essence, it got no ventilation at all. Plus it was on carpet, which isn't the most cooling material...Mine is on a bookcase too, right next to the 360. I've never had any problems with it either...
EDIT: Wow, we should just rename this thread to "Next-Gen Consoles Discussion" since half the time we're talking about the 360.
EDIT again: Does anyone know when Afrika and the next Wipeout come out? Right now, I might just have to sell my PS3.
...to bump up to a 60GB, of course. Turns out I need Wi-fi.
