system is on a wooden floor just about in the middle of the floor, only thing I haven't done is put it on stilts LOL!
I'm struggling with this overheating thing because when it was freezing the Xbox itself was only warm to the touch not at all hot, even the powerpack's not what I'd call hot.
Anyhow thanks for all your help, I'll give it another blast tonight and see what happens, might set the clock back again
