Which fan is defunct?
The failure code according to the extensive (detailed?) Apple Hardware Test:
4SNS/1/40000001/:TBIT-5.000
One of two thermal sensors seems to be malfunctioning. But how do I find out which one?
Thx
Update
Here it is:
Last 4 S/N digits: B1GA
Is this a good question?

Thanks for the hint: got Temperature Gauge 4.1 from the App-Sore: All fans are functioning normally at 2.000 rpm. I'll have to perform a total tear-down of the MBP to see whether there are any thermalsensors attached to the heat-sink or the main board.

Not so fast here ... There are multiple sensors. If both fans show they are running then you have a different problem. Can you give us the last four digits of your S/N so we can correctly ID which model you have.
