It seems all that burning rubber and gratuitous nitro boosting in the Ridge Racer 7 demo took its toll on a lone PS3. Kotaku snapped this picture of a Sony rep bravely averting disaster by pointing some sort of advanced cooling mechanism into the console's compartment. System anomalies crop up at trade shows all the time -- we salute the fan-man for his keen sense of practicality. He probably doesn't lock his dog in the car while he's out shopping either.
