Question Ryzen 5 2600X idle temps near 80 degrees idle and 95 gaming! Please help!

[SirMephistoPheles]

Description of Original Problem: Recently, like a week ago my CPU temperatures started going really high even when nothing but Chrome is open. Around 78-80 degrees. When gaming like Java Minecraft with some shaders CPU temps go over 90 to 95 celsius and I can feel the glass part of the PC case hot as hell which scares me. Even when I'm in the uefi BIOS setting CPU temps won't go below 50 celsius which is still very hot. The whole setup isn't even half a year old and I barely if ever put my PC under demanding stuff or stress. I take care of it. Yet I cannot find the origin of the issue.
Troubleshooting: I've tried manually setting CPU fans to maximum but the temeratures barely go any lower. I tried setting power consumption plan in windows control panel from maximum performance to balanced or even power saving but no change. I also carefully removed the cpu cooler, cleaned it and the CPU surface off residual paste, repasted it and put the fan carefully back. No change. Did the same again but with a different, similarly performing Arctic CPU fan. No change. Added a secondary fan next to the main CPU fan. Degrees lowered from 80 idle to 75 idle. It's not much, still very hot.

reset the BIOS by jumper

update the BIOS of the motherboard (within the BIOS using the EZ-flash manu)

be sure the cooler is really tightened to the socket

I followed the motherboard manual and cleared cmos. I just updated the bios via Ez flash menu. Not much of a change sadly. It seemed to work for a minute because after startup idle temps showed to go down to 40 celsius but after another reboot it's back at 75 again. The cooler is tightened, I made sure.
