8700k cannot exceed 47 without causing a delay.

It seems unlikely to push the 8700k beyond 4.7Ghz without damaging it. The temperatures you're seeing—85-87°C with a low voltage—are quite high, especially under stress. It's unclear if this is typical behavior for the i7 8700k during intensive tasks like Prime95, and it might not be safe to attempt overclocking.
I have a few thoughts on this. First, your temps doing this will be much higher than your temps while gaming/other use. While I wouldn't allow the temps to get much higher, I'm not worried about 85C during stress testing. As long as your gaming or other use temps are back under 65-70C or so you'll be alright. You also have a seriously high tmpin4. 102C? That could be a part on the motherboard frying. Check your board near the CPU and see if you need active cooling on those sinks. (I just woke up, can't remember the name for the VRMs. Yay! Brain finally booting up!)
I'd like to point out that there is only a 400MHz difference between 4.7GHz and 5.1GHz. That's not enough to make me push a chip if the temps or voltage get out...

To be honest, if you have to cause the temps to go to high or increase the Vcore too much to get to 4.8 or 5.0, it's not worth it. 4.7GHz is still really fast.

I'm not sure why it's so high? I just built this computer yesterday. I have 2 fans on top of my case blowing a lot of air.
Edit: Now my TMPIN4 is 119C and slowly increasing Damn
🙁
You're experiencing issues with your AOI cooler not delivering airflow to the VRM heatsinks. Try attaching a fan directly to them and observe if the temperatures decrease. Both the CPU and VRMs require adequate cooling for optimal performance. Overloaded VRMs may hinder stable power delivery to the CPU, limiting optimization potential.
I think the fans at the back and top are probably exhaust fans? None of them line up with the area you highlighted, and there doesn’t seem to be any actual airflow. Even worse, there’s a bracket on top that just traps air. If all three of those fans are exhaust fans, you should try turning some in the opposite direction to push air in. Or as I mentioned before, consider attaching an old fan to that spot somehow. You’ll need to move the air across that section.
It seems the fans at the back and top are likely exhaust fans, but they aren’t aligned with the area you indicated, and there’s no actual airflow. The top bracket is just trapping air. If all three are exhaust fans, consider flipping them to direct air in. Alternatively, attach an old fan to that spot. You’ll need to move air across that section. This issue appears to be common with Z370 Gigabyte motherboards. You should check the official support page or forums for more details.
