Thanks for the reply. I'm sure your Noctua is a great air cooler but I seriously doubt it will cool better then my Capellix 360 AIO. Are u running the Newest Prime95 with AVX instruction test? The temps we are seeing are with AVX enabled. My CPU idles in the 20's-30's with Ambient room temp at 72-75F. I stay in the 50's with most tests/tasks but if It's something with AVX, that is where the CPU will spike in tempI'd like to invite both of you to joining me on the darkside and buying a D15. I have a 5900X and am doing a lot better than both of your outcomes. Blowing those Corsairs out of the water.. I can't get mine to go over 61C after 10 minutes of a Prime95 24-thread torture test blend in a 19.6 liter mITX case, holding 4.5 to 4.6GHz on all cores. In games as you're describing, I'm not going much over 50C. It does sound like temps you're getting on that AIO are within expected range.
