So, when the machines first hit the shops last year, Volish switchboards were flooded with complaints that machines were overheating and cutting out.
Now a group of German modders at www.modcontrol.com think they have found the reason. They have checked two Xboxes and found that the protective foil on the GPU heatsink's heat transfer pad didn't get removed during assembly.
The protective layer was probably put on by the manufacturer of the heatsink to protect the heat transfer pad from dust, before final assembly.
But the failure to remove the wrapper caused the GPU chip to sit against the plastic protection foil, instead of the heat transfer pad.
