Wrong CPU temperature is being reported

[Agent92]

The CPU-temperature reported in FreeNAS is extremely low, around 10c when the ambient is around 23c with an air cooler. So it can't be correct. Also when I put the CPU under load the temperature drops to 0 as you can see in this graph.

Anyone know why this happens and if I can fix it so I can get the temperature reported correctly?

CPU: AMD Phenom 8650
FreeNAS version: 11.3
