I'm traveling home and I left my PC running 24/7 consuming 150-200 kwh under 100% temperature simulating algorithms and statistics stuff. I couldn't get a GPU to do it. So this is my only option.
My CPU, an R7 5800X3D, is cooling by an Arctic Freezer II, never gave me any issues, under normal conditions under 100%, it gives 80C°.
Before leaving this time, I simply opened my windows lol I bet my apartment is like -4 right now.
