ok..i just started mine up for the very first time and it idled for about 2 min then the top hd3870 gpu got hot like starting to burn my finger hot. everything powered on and all fans were working. the bottom hd3870 was hardly warm..the cpu was at 36%c. i didn't have anything installed as it was the first power up so i switched cards/cables to see if it was maybe the card or a cable and the same happened. so i shut it back down... everything is brand new.. is it normal for the top gpu to get that hot? there is no softare installed yet and the hd3870 fans were spinning very slow i was going to start installing stuff untill i felt how hot it was.
