Hi there,

I'm trying to figure out the current CPU Fan Status via openipmi
on a PowerEdge 2850 and PowerEdge 2950 with Debian Etch installed.

If I request the fan states openipmi returns a bunch of fan infos,
but I could not determine which of the fans belong to a processor.

Is there a way to locate the fans which belongs to a cpu, 
eg. by sensor id, or something?

Regards,
Michael
