Is there any possibility of somebody marketing a fanless POWER9 cooler similar to the HP Z coolers (http://www.hp.com/global/hpinfo/newsroom/HPZWorkstation2015/HPZCoolerforHPZ840WorkstationDatasheet.pdf)?
Maybe this would not be feasible for the 22 core chips but it would be very interesting for 4-core. Not only is it silent but it also eliminates one possible type of mechanical failure.

There's the 2U heatsinks. I use one in a Blackbird. Works well enough but I would only use it for the 4-core.

You have air moving across it in some capacity though? No issues with throttling or anything?

The HP Z cooler is not simply fanless, it is based on 3D vapor chamber phase-change cooling with staggered hex-fin heat exchangers
HP published some research about this technology (https://www.labs.hpe.com/techreports/2016/HPE-2016-85.pdf)

Yes, there are case fans. It's never gotten into overheat territory since those were installed.
