I7 9700k high temps and voltage

[Th3Sentinel]

Hello everyone. I've just bulit a new pc, been waiting for it for a long time and I came up with some issues with it.
PC: I7 9700k
Noctua NH-U14S
Case : Silentium PC Armis Ar7 with 2 additional fans
Gigabite Aorus z370 k3 gaming
16 GB of Corsair Vengence 3000 Mhz Ram
Gtx 1070 from EVGA

1. First thing I noticed is that temps were high in idle. In high 30 low 40s. But it was idle I didn't mind. But when I started playing I noticed after some time that my frame rate dropped from having 300 fps in csgo down to like 150. I thought to myself that can't be right so I checked and the temps were in the high 80s some cores were at 90°C. That's not good. Turned all the fans to max rmp so it's better but still very high.
2. I noticed that my voltages are high while I was trying to figure our what's the issue. I'm getting roughly 1.45V. What the hell ? I checked online and I should be getting around 1.25-1.3 So that's probably the issue of my heat. Tried to lower Load line calibration In bios but I wouldn't let me so I found it in a motherboard software app that let me change it from high to medium or sth like that It wasn't really precise.
3. So my question is: is it motherboards fault for giving too high voltage? Is it my bad cooler and should I just go liquid ? Or am I just unlucky on the silicon lottery and I have a ****** cpu? Ps; I'm pretty sure that the 9th gen i7 should hit 4.9 ghz at least on 1 core right? The highest I've seen mine go was 4.7 which I think is due to the temperature throttle. I need help plz save me ;*

Load optimised settings in bios. Dont load the XMP profile and reboot

Check temps and vcore and report back.

Did that temps and vcore are roughly the same still hitting 1.4

Lower the voltage to the chip, with CPU's power approximately squares with voltage so what ever you can do to lower it the better. Use offset voltages and lower it manually in the bios to 1.2V and start from there, if it crashes up the voltage 0.02V and try again. 1.45V is way to high to start with, I'd say 1.3V is the max I would go really.

Also make sure you have all the fans in the system running the right way, generally running the airflow from front to back, and set up fan curves for all the fans in use.

What are you using to check the voltage? To be honest, with the Noctua cooler and the temps you are seeing I do think the voltage is set way too high.. Try other monitoring programs, like HWinfo64, just incase they are being reported wrongly.

Report back what the voltages are set to in the bios. Also, to start with, disable any multi-core enhancement just until you know what the hell is going on.

Googling it now, this UEFI is ***** compared to the old Asrock one i had in my previous mobo, so it wont allow me to mess with the settings dont know why. But ill start as soon as i find out how.
In bios voltage is set to auto, it was displaying 1.3V also. I am using HWinfo64 for temps and vcore readings.

Latest bios?

yes sir

Looking here: https://www.anandtech.com/show/13400/intel-9th-gen-core-i9-9900k-i7-9700k-i5-9600k-review/22 Those are the voltages you should expect to need for different speeds although processors do vary.

Can you change the voltage from auto to manual? Then you should be able to change it somewhere close after.

it dosent allow me to. im browsing online too see if i have to enable/disable something first before they'll allow me to.

Little update.
Went down with the voltage -0.140 so far trying to go down little lower so we'll see. Ran prime95, highest its been is 1.390 on 1 core roughly 1.35 on the others.
Temps went up to 98 degrees though im slowly getting ****** il give you guys an update once im on the lowest voltage the system will boot.

update 2.
After all that playing around in the bios nothing seemed to be working. I loaded optimal bios settings so back to default and hit the stress test cause 1 guy wanted my hwinfo64 readings. Hit 100 degrees and pc crashed. Think im gonna go to the store on monday morning and tell them whats up cuz this is just not right.
Thanks everyone for your time if you have any suggestions im still willing to check them out but im slowly giving up ..
