Hi!
I’m completely unfamiliar with OC, but here’s the setup of my PC:
Case: Deepcool Earlkase RGB, 3x120 Arctic cooler fans at the front and 2x120 Deepcool fans on top
CPU: i7-8700k
Motherboard: Asus Prime Z370-A
RAM: 2x8GB G.Skill Ripjaws V 3200mhz
Power Supply: Corsair RM850x
CPU cooler: Deepcool Maelstrom 120T with Arctic Silver 5 thermal paste
I use AIDA64 Extreme for monitoring temperatures and other metrics.
In the BIOS, I ran Asus EZTuning, then configured the PC for Gaming/Editing video. The CPU cooler was set to water cooling, and I manually adjusted the RAM speed to 3200mhz.
The AIDA64 results show:
CPU Clock: 5150Mhz
RAM Clock: 3200Mhz
CPU Core: 1.456V
CPU VID: 1.448V
DIMM: 1.360V
CPU Temp: 35°C at idle, 22°C with room temp, 70°C during CPU stress test (only CPU box checked)
Are these readings acceptable? I’ve heard 1.45V can be risky.
What about my temperatures?

The voltage core is a bit too high, isn't it? What velocities can you achieve if you restrict the core voltage to a 1.350 to 1.400 range? Temperatures should remain below 80 to 85 degrees Celsius for reliable, continuous operation.

i don't understand or prefer not to adjust manual voltage settings; instead, i use tools like asus utilities. the alternative approach i tried was resetting everything to defaults, then selecting "extreme tuning" in bios, which resulted in 1.376-1.456v and 4.7-5.0ghz based on load and processes. (i think my temperatures are acceptable?)

Setting the manual Vcore is quite simple.
1.450 volts is considered high, but it's acceptable as long as your temperatures remain below 80–85 degrees Celsius.

You're going to fry that chip quickly at 1.45v. At that level, cooling the chips isn't as important. What matters most is the electrical stress you're applying to the CPU circuits. You're putting way too much pressure on them.

thank you, the adjustment to 1.35 has been made, is that acceptable?

1.350 Vcore allows continuous operation throughout the year provided temperatures remain between 80-85 degrees Celsius.

you mean 75-80 on idle?? or on gaming? i don't get 75-80c even on 1.45v and on stress test.. is that normal? (unless i am doing something wrong in stress test)

He refers to a scenario where the CPU operates at maximum capacity with a temperature range of 75 to 80 degrees under heavy load. During the Aida64 stress test, verify three areas: CPU stress, FPU stress, and cache stress. After completing the test for 15 to 20 minutes, observe the temperatures.
