I just think OP is confusing everyone. I know it will show CPU, but you also assume he knows how to work that but not HWINFO? These apps are not rocket science.
Well I'm not confused. OP worried about spiking behaviour of CPU temp, and asked also about the max temps he sees, if its ok (65~70C). ZEN2 is very easy to spike to 60s and 70s.
And what I got is that he use afterburner to monitor his CPU temp.
@PandaH05 this is what mine looks like on normal usage:
So the spiking thing is normal. If you CPU is staying below 80C its probably fine.
These CPUs have max operating temp at 95C but thats not the spot to work on.
Im not sure tho that 4.2GHz with constant 1.35V is ok.
You must consider that temp is not the only factor to take into account for longevity of a CPU. These chips are not ment to work with constant voltage.
I'm not saying that the CPU will definately be worn, but its a possibility.
