I'd love to have a desktop like this, but I wonder how loud they are. I'd expect that POWER9 Heatsink/Fan assemblies are made more for data center use, where noise is an afterthought.

It's be awesome if they had heatsinks like this available for it: https://www.techpowerup.com/222984/noctua-unveils-prototype-.... I have something similar, and all I need is a slow 120mm fan to keep everything cool.
