Hi I am somewhat new to the world of overclocking but I was wondering if my voltage and Temps are safe for my rig:

i7 6700K
Noctua D15
Z170A Xpower Gaming Titanium Edition motherboard
Corsair 750w psu

Stress test @:
Cpu at 4.5ghz
Voltage at 1.30
Min temp: 25 degrees Celsius
Max temp: 72 degrees Celcius

Tried going 1.25 voltage but watchdog error. Am I better off trying to hit 4.3-4.4ghz at 1.25 or is 4.5ghz at 1.30 going to be okay?
