Very odd. The processor is an Athlon 64 X2 4850e. Being one of the newer
energy efficient 45 watt models I suppose there might be a difference
in the temperature sensor. It might also be an issue with the
motherboard (Foxconn FC-6150M2MA-KRS2H). After I got the motherboard I
needed to upgrade the BIOS in an attempt to fix an unrelated problem.
Prior to the update even the BIOS reported silly high temperatures and
I remember FreeBSD reporting a constant 40C but I don't remember
whether this was from sysctl, k8temp or mbmon.
I don't overclock the system so after satisfying myself that it doesn't
have any tendency to overheat I no longer have much need to monitor the
CPU temperature so I think the way my system reports temperatures will
just remain as one of life's little mysteries.
