Noctua NH U9B Cooler SE 2 with Silverstone Sugo SG07

We disabled the single 92mm fan completely for these results and ran our tests again.

To measure these temperatures we left the system at idle for 90 minutes then tested again under load. The cores would hit 80c but even after 3-4 hours of testing never exceeded this point – the sheer mass of the heatsink was able to keep the 655k cool. It would be possible to run this system passively cooled long term as 79/80c is not dangerous, especially with default voltage. Whether we would however is another question.

Measuring noise levels with the single fan completely disabled did not lower our meter reading at all, we can therefore take an educated guess that ambient room noise and the noise of the PSU is generating the rating of 16.2dBa. We can also assume that leaving the fan on, with the blue, ultra low noise adapter is a better long term option as temperatures are lower and noise levels are not increased at all.
