k8temp was superseded by amdtemp in around 8.0-8.1 release (I think). 
Though it doesn't matter when both don't work.
I've managed to get some data from onboard ITE chip. Accuracy is a 
really big concern and I doubt it can be trusted. But I've measured 
idle/load temperatures by software and additionally using infrared 
thermometer when I was building the machine and when I see approximately 
the same values I'm thinking it is okay.
Another indirect method for me is to monitor fans. When I can see all of 
them working fine and environment temperature is known to be within 
reasonable range then I can expect  CPU temperature to be quite 
predictable. To use this you have to trust your thermal compound as may 
dry with time loosing its capability to transfer heat effectively.
