CPU Temp on AMD Ryzen

Some useful info:

It looks like the new AMD Ryzen chip have some discrepancies on the TEMP given by many monitoring tools.
Confirmed on:
Code:
sysctl -a | egrep -i 'hw.machine|hw.model|hw.ncpu’
hw.machine: amd64
hw.mode: AMD Ryzen Threadripper 2950X
hw.ncpu: 32
Below you can find some information and explanation of the AMD offset in previous gen RYZEN chips.
OC_Benchmark_POST

It looks like with the CORETEMP app the temp that is being shown is the tCTL:MEANING there is an offset of 27C degrees being shown with amdtemp_load for Ryzen on freebsd....

Code:
sysctl dev.cpu | grep temperature
dev.cpu.0.temperature: 57-61.1C

I took down my water-loop 3 times trying to see why the temp were this ASTRONOMICALLY high in dies, maybe it was pump? A leak? The thermal paste? Algea?... My previous Intel chip temp were never this high on load, previous I was pretty much on 28-34 C all day idle. I have somewhat powerful loop with (3) 560 radiator , X3 reservoir and X3 pumps so seeing anything above 55C+ is a surprise to me unless my pumps fail. For those members ON AIR with Ryzen chips you can safely assume on FREEBSD Coretemp to see 65-75C on idle just do the OFFSET by 27C easiest workaround.

I tested with sysutils/mbmon

Reading seems to be more accurate but it is crashing will do some testing in future....

AMD GPU Temp I do not have any so I have not tested but it was suggested to use sysutils/radeontop or x11-drivers/xf86-video-amdgpu might have TEMP reading for GPU.
