Yes i am using stock fan inside case, next mouth ill buy another fans. Room temperature is 15°C. I didnt changed single think in BIOS, well if you dont know what things do or how they work, better dont play with it. So i didn't play with BIOS, everything is default expect
RAM speed i changed it from 2400Mhz to 3000 MHz.
But still if its that high temperatures, case fans would change it for 20 degrees? Im not sure.
I added one fan from really old pc (propably one things what is still wort use) without that temperature were around 90, at touch it was verry hot. I couldnt hold hamd at case more than three seconds.
EDIT: i tried to run Fan speed at 80% with that on witcher it hits GPU temperature on 60-75 ... and CPU around 70. But With same preference Metro exodus GPU has 65°C which is not that bad, and CPU strikes 87°C its high,.
Maybe phisics helping with incrasing temperature, if i´m not wrong, GPU fans pushing wind inside graphic card, not outside. Graphic card is located under procesor. than heat from graphic card helping overheating procesor. thats not good, but i belive we will find right way to get optimal temperatures.
