Questions about Noctua Nh-U14s Tr4-Sp3

It says on the Noctua website that the cooler is compatible with the sWRX8 socket, but the cooler is rotated 90 degrees and the fan blows from the bottom up, as I have seen some sWRX8 motherboards that have the socket rotated. RAM clearance should not be a problem if the RAMs are not higher.

I have it in use with only a 2950X with a second fan on the cooler. Room temperature warm at 25°. Case with some insulation, so airflow-wise not ideal. At limit 180W (i.e. significantly lower than yours) the temps are already approaching 68 degrees. But it's quite enough to get above the base clock. I can hear the part quite clearly, but I don't know how other fans make noise. A water cooling system broke after a short time. The selection for Threadripper-adapted AiO is unfortunately very narrow. The 280W would worry me a bit. An airy case and a cool environment will certainly help. According to Noctua it works, but Turbo is nothing: https://noctua.at/de/products/cpu-cooler-retail/nh-u14s-tr4-sp3/cpucomp

Yes it‘s a good cooler. I‘m using the 3970x and tried the push-pull version with it. I don‘t know the temperature but it‘s not getting hot.
