CPU temperature reading

Hello,

I am getting impossibly low temperature readings on a new system
running FreeBSD 10.0-STABLE #0 r268555 amd64:

# sysctl -a | grep amdtemp
dev.amdtemp.%parent: 
dev.amdtemp.0.%desc: AMD CPU On-Die Thermal Sensors
dev.amdtemp.0.%driver: amdtemp
dev.amdtemp.0.%location: 
dev.amdtemp.0.%pnpinfo: 
dev.amdtemp.0.%parent: hostb4
dev.amdtemp.0.sensor_offset: 0
dev.amdtemp.0.core0.sensor0: 17.2C
dev.amdtemp.1.%desc: AMD CPU On-Die Thermal Sensors
dev.amdtemp.1.%driver: amdtemp
dev.amdtemp.1.%location: 
dev.amdtemp.1.%pnpinfo: 
dev.amdtemp.1.%parent: hostb10
dev.amdtemp.1.sensor_offset: 0
dev.amdtemp.1.core0.sensor0: 19.1C

The BIOS only says CPU temp "Low".

Smartctl shows 30C for hard drive temperatures. The ambient temp in the
room is about 24C - defective CPU thermal sensors?
