amdtemp0 shows odd temperature

Looking at envstat output on my machine I see a bit odd output from amdtemp0.
The CPU is

cpu0: AMD Athlon X2 or Athlon 64 X2 (686-class), 2500.01 MHz, id 0x60fb2
cpu0: "AMD Athlon(tm) Dual Core Processor 4850e"
cpu1: AMD Athlon X2 or Athlon 64 X2 (686-class), 2500.01 MHz, id 0x60fb2
cpu1: "AMD Athlon(tm) Dual Core Processor 4850e"

envstat output is:

[aiboost0]
    CPU Temperature:     30.000                                degC
[amdtemp0]
       CPU0 Sensor0:     14.750                                degC
       CPU0 Sensor1:      6.750                                degC
       CPU1 Sensor0:     14.000                                degC
       CPU1 Sensor1:      7.000                                degC

I really don't believe amdtemp is showing the correct temperature.

Should I open a PR, or is this a known problem?

NetBSD 5.99.3 on amd64.
