If a "system halted, code=13" message on the LCD this can mean more than just a cpu fan
failure, to determine which fan/thermal error caused the halt, run up system while logging the
output from the front panel port marked 232, the last message before the system stops should
be one of these :-
"cpu temp = XXXdegC, shutting system down...."
"router temp = XXXdegC, shutting system down...."
"summer temp = XXXdegC, shutting system down...."
"psu temp = XXXdegC, shutting system down...."
"cpu fan slow, shutting system down...."
Additionally, if a chassis fan is misbehaving the following message is displayed :-
"chassis fan X slow, setting all other fan pwms to max"
where XXX is some appropriate value.
