    Phoronix: Cooling AMD EPYC With Noctua Coolers: NH-U9 TR4-SP3, NH-U12S TR4-SP3, NH-U14S TR4-SP3

    While Austrian PC cooling manufacturer Noctua is mostly known for their high-end enthusiast/gamer oriented cooling products, they do offer a line-up of heatsinks for both AMD Ryzen Threadripper and EPYC server processors. In this article we are trying out the NH-U9 TR4-SP3, NH-U12S TR4-SP3, and NH-U14S TR4-SP3 heatsinks on a 32-core / 64-thread AMD EPYC platform for seeing how well these air coolers will do with AMD's promising server platform.

    What about the loudness of those?

      I'm interested in noise levels as well. Even power consumption for that matter at idle.

        All of the Noctua 92/120/140mm fans tested are extremely quiet. Whoops, forgot to point that out in greater detail but unfortunately don't have the means of providing any useful sound measurements.

          I just got my EPYC 7401P and NH-U14S. The temperature is awesome, very similar to what published in article. I can really only hear the fan if my ear is less than half meter from the heatsink, and I use an open test bed.

            Why are the 2 fan versions performing worse?

              Is Blender Game Engine doing multi-threading at the same level as the test in the article does?

                It's a shame that you didn't benchmark it long enough to reach steady-state so that you could legitimately come to the conclusion you presented.



                What this graph shows is a steady rise in temperature, which isn't at all a clear indication that the cooling solution is coping well.

                  The 2x 120 mm fan version is only worse than the single 140 mm fan. But always better than 1x 120 mm fan.

                  I wouldn't have guessed the single 140 mm would be quite so strong, but otherwise not surprising.

                    I highly doubt it. At decent resolutions, with decent quality rendering options enabled, game engines tend to be GPU-limited, even on far less powerful CPUs.

                    In contrast, the non-realtime rendering benchmark he's using is doing rendering on the CPU, itself.
