IPMI polling on Dell PowerEdge R200s (and other Intel CPU rackmounts): polling the Dell PowerEdge R200 using IPMI-over-LAN, it may be surprising to find the 'Temp' sensor reporting comfortably arctic temperatures, low to the point of being sub-zero, and critical failure:

Temp             | -52 degrees C     | cr

In moderately recent time, Intel have taken to giving this temperature not as an absolute temperature, but have instead redefined the scale of Degrees Celsius so that it is measured relative to the "melting point" of the CPU.

Once this is compensated for, it should give the actual temperature of the machine.
