The ice giant thermosiphon seems to be the state of the art right now from what I’ve seen. To the point where that’s being used by the world’s top overclocker instead of water cooling loops. If I were building a system I’d just slap one of those in, buy some Noctuas for quieter fan operation and ignore it, and let the CPU turbo to its hearts content.

On my 32 core ThreadRipper I’ve been running an Ice Giant since it came out. It’s excellent. The only gotcha is to ensure your case can fit it in.

  How big is this thing next to something like NH-D15?

I didn't know about them, so I've checked, IceGiant ProSiphon Elite vs Noctua NH-D15, https://www.youtube.com/watch?v=a0OQxbMvo80 https://www.youtube.com/watch?v=a0OQxbMvo80 At min 26:30 it's shown test results, and the performance seems better with Noctua NH-D15. Less noise (less rpm) for the same temperature dissipation. Noctua's performance with low noise is among the main reasons why I own one since several years ago ( And also why I choose air-cooling over water-cooling). It would be interesting to know if someone has beaten them (At same performance, less weight would be something for to take in account).

  The IceGiant ProSiphon has fittings for 4 x 120mm pwm fans. Fitted on my ThreadRipper, I switched the stock IceGiant fans out for Be Quiet Silent Wings. A significant extra cost to be sure. I'm sure some Noctua fans would fit. Best of both worlds. Any judgment on thermosiphon technology (where noise is largely not a factor) should not be conflated with a judgment on the quality of attached fans. Sold together as a product, though, I suppose it remains relevant. Remember to compare any noise savings against the total noise. e.g. I have 8 other fans in the box. If memory serves when I built it, tech websites were reporting that the temperature under load with an IceGiant was lower.

World’s top overclockers use liquid nitrogen

The issue is that heatsinks for quiet operation are better off with larger gaps between fins (smaller number of fins per inch, FPI), and Thermal Siphon goes the other way for best operation with powerful, loud fans.
