air cooled cpu low temp

I get 14 C while doing nothing and closing everything
FX 8320
tested it with 2 prog (core temp, CAM from nzxt)
, doesn't seem normal

You can't be lower than room temperature

I heard there're some problems with AMD CPUs that you need them to work heavy for few sec to see their real temp.

Also try using Real Temp, it's a free software.

^ This. Real Temp displays the most accurate temp readings.

The only way it can be more accurate is for it to label the temperature sensors correctly. The sensors are the same, the look-up table is the same.

It's like that with all FX CPU's, I have FX-6300 and and its temp sensors report normal values only on load. I use CPUID Hardware Monitor, it shows both core temperatures and "CPU temperature", which is a read from the motherboard based sensor (it's used by motherboard to control CPU fan speed). That CPU temp, or socket temp, shows normal values all the time, for me it's ~30C on idle, and up to 60C on load, depending on OC. Cores show 5-10 degrees lower temperature on load, doesn't really make sense but it's normal. Just make sure the cores don't go much above 50C (62 I think is the red line for cores, 70 for socket).
