CPU running hot despite returning to defaults after overclocking

Hi,

I built this computer about a month ago and decided to try and over click it. It worked fine and I never had temp problems before I tried all this. It didn’t go well and it refuses to idle at reasonable temps now.

Intel i5 9600k
ASRock - Z390 Pro4 ATX LGA1151 Motherboard
Cooler Master - MasterLiquid ML240L RGB 66.7 CFM Liquid CPU Cooler

I tried overclocking my cpu to no avail. It immediately hit 115 degrees C. I tried to dumb it down and was still running hot so I decided to revert back to UEFI defaults. Still though, if I start any game or do a benchmark, it exceeds 80 or 85 easily and it idles around 60-70. To be honest, I didn’t know at all what I was doing in the bios, the guides I read didn’t really seem to relate to the options I had in front of me so I basically just tried some things, dumb, I know.

My liquid cooling pump appears to be running, CPU fan at 2k rpm which is its max. I’ve orderded new thermal grizzly thermal paste to reseat it but I don’t understand how that could be a problem because it worked prior.

Is it possible I just ruined something in here?

Please give me a hand, let me know how I can help.
 
Bios. I reset it all to defaults I believe but, I have the CPU Core/Cache Voltage option set to Auto and the CPU Load Aline Calibration set to Auto as well. When I boot up, the voltage shows it operating at 1.040V
 


When you overclocked, what voltage?
