For those who are looking for a solid CPU cooler. I was having a 212 Evo on my 9700k no oc and the idle temps were 50-55C. I changed the CPU cooler and the 2 case fans with the Noctua 15s (CPU cooler) and nfs12a (case) and the idle temps are 30. Maybe my Evo was broken Idk but the differences in noise and thermals are significant! I will edit this thread when I stress test the CPU with AIDA64.
