Hi Jean if only I was getting random readings, but the readout I'm seeing doesn't look random at all - it's typically 80-81, but will increase to 86 when I'm stressing the system (the CPU-temp will rise to 62/63 at the same time). I'm currently waiting for the board to be replaced, so I can't tell you exactly what lm-sensors says about the type of sensor, but I think it said it was "transistor". Regardless, I guess I should be ignoring it when Gigabyte says it's not there ... /Per Jessen, Z?rich
