It's done it ever since I bought it from new last December. So I am out of warranty by a month now. Iv'e probably only ever turned it on about 15 times in that whole year. It occurs during cold startups, if I leave console on for a while, turn it off for about 15mins, it wont make the terrible noise. I'm sure it's coming from the fan, perhaps a bad bearing, and takes a while to smooth out. Anyone else had the issue before?
