The command is prtdiag -v, requires root priviledge. Here's a partial output, pay attention to the current column.
System Temperatures (Celsius):
0 OK 29 26 34 stable 1 OK 35 34 38 stable 2 OK 31 27 35 stable 4 OK 30 26 34 stable 5 OK 34 32 36 stable 6 OK 31 27 35 stable 8 OK 30 26 35 stable 10 OK 33 30 37 stable 12 OK 31 28 36 stable 14 OK 33 29 37 stable CLK OK 28 26 29 stable
The I/O board (1) always/most of the time has higher temperature.
