I booted my HP Pavilion zd8215us and I immediately invoked chkCPUTemperature.
The first temp reported was 52C, which is 125.6F. This leads me to believe
that acpi has an anomaly regarding temperature measurement. The ambient temp
was 71F (21.6C). The machine had been off for over eight hours.
Here's chkCPUTemperature:
#!/bin/sh
# $Id:$

# CPU Temperature Information from ACPI
POLLING_RATE=`sysctl hw.acpi.thermal.polling_rate|awk '{print $2}'`
while [ 1 ]
do
sysctl hw.acpi.thermal.tz0.temperature
sleep $POLLING_RATE
done
