I currently have a ASRock Z390 Phantom Gaming 4-IB mobo with a Zotac RTX 2070 AMP Extreme GPU. I've been running into severe overheating issues when playing graphic-intensive games (e.g., The Division 2, Cyberpunk) where the CPU temperatures have been climbing to 90-100+ degrees and the GPU hitting 80+ degrees as well. I've seen voltage average above 1.4V and these temperatures were after setting the fan profile to full speed on the CPU in the BIOS and GPU fan profiles to essentially 100% at 70 degrees.
I'm running out of ideas on why the temperatures on climbing on both constantly and one fix I saw online was that the pre-set voltage was ~1.35V and I was looking to tune it down. Where can I find this setting in the BIOS and what would be a normal level to put it at£ I'm open to other potential fixes as well!

Hey, I have this same motherboard in my iBuypower. I have noticed that in the BIOS my processor says that it is at 100C. It will say this if I was just running a game, or if i just started my computer up in the morning. I am thinking that the temperature is not accurate on mine. My processor is water cooled, and the fan output doesn't feel like it is getting that warm.
Does anything happen when you are running games, system shut downs or anything like that? If not, I am thinking that the temperature sensor might not be reading right like mine.
I am curious if you found a fix though, also, what kind of cooling are you using? make sure that the thermal paste if the cpu fan was removed for any reason, and power is connected to the fan.
Also there is a BIOS update I found for this motherboard, I found one on the ibuypower website that has a higher versioon than is on the asrock website. Both of the versions worked for me: https://www.ibuypower.com/support/driver-downloads" rel="nofollow - https://www.ibuypower.com/support/driver-downloads
