1. If you mean it is fixed at all times at 1.36, I would recommend otherwise ... best to set it so it uses maximum voltage )offset methois) and let voltage rise with the CPU speed when system overclocks to suit load then clok back to 800 Mhz. 1.36 is higher than average for 4.6 Ghz.... that's more typical to say a 4770k
At idle I'm at 0.71 Vcore and 800 Mhz... at max OC VCore will jump up to 1.48 volts for millisecond or so when AVX is present and stay from 1.38 to 1.44 otherwise. Pretty much 1.38 or so most of the time when using RoG Real Bench, but when AVX is present, voltage will jump up to 1.41 - 1.44 .. with occasional pops up to 1.48. In gaming, don't see anything near that.
Be aware that whatever you see when load testing and regardless of the 1.36 setting, when AVX is present, voltage will jump from 0.10 to 0.13 extra. So with 1.36 setting, you could jump to 1.49.
To get real temps / voltages that you can compare against others, use RoG Real Bench fpor testing purposes... many games only load load the CPUat 40% max.

Again, without knowing what the laod was, no way to say if temps are good
