Hmm, there are several ways the Hyper 212 have had the heat pipes attached to the bottom plate over the years. The original one had round heatpipes at the base with gaps, then they went to flattened and polished with gaps, then they went to flattened, polished and right next to one another, then for the black and the V2 version, they have flattened and polished with a bit of a gap between the heatpipes and the base. With the base now acting as it OWN radiator with fins, this last setup would be MORE effecient to remove heat. Both the V2 and the RGB black editions are my current recommendations, but all of the hyper 212s have been great coolers.Pretty big stretch to call this an Evo V2 when it doesn't have the flatted full coverage heatpipes of the original Evo.
A Noctua NH-D15 on a 9900k maxes out in the 70's degrees with no OC.I have the Hyper 212 EVO black edition which has a very similar mounting system. It works fine as long as I don't go crazy overclocking the CPU. With a i9-9900K and a 4.6GHz OC, I can run the fan at low speeds and have the temp max out at around 70C. Nice and quiet and good enough for me! The black looks nice had the RGB fan hooked to my ASUS mobo rolls slowly through the colors.
It's somewhat amusing to see people post AIDA 64 results only to find out that they checked off all, or almost all, those boxes.AtotehZ, What? You must have some miserable i9-9900K if you cannot get 4.6GHz at 70C with full CPU load. He is mine. I have the CPU fan on my Hyper 212 RGB Black set to 30% ALL THE TIME so it is always quiet. Here are my results (only visible on the forum page). Seriously something wrong with your results. Redo your thermal paste and make sure the cooler is firmly set on the heat spreader. My results are typical for pretty much all users of the i9-9900K on air. PS running longer does NOT heat soak the cooler and it is extremely stable with these being very typical temps over hours of running.
