IMO, Noctua could make a killing if they designed a pump that doesn't vibrate as much or produce as much motor noise.
Or, alternatively, whatever happened to their active noise-cancelling fan accessory? Slap that between your PC and where you sit, and you don't have to worry about how loud your PC is.Reply
Companies have been showing off non-rigid heat-pipe coolers (thermosiphons are just heat-pipes with unidirectional flow) at trade shows for well over a decade, and thermosiphon cooling systems have been in use for many decades before then. The big problem is that for then to work with water as a working fluid (as in rigid copper heatpipes and vapour chambers) the flexible tubing needs to be gas impermeable - else the pressure inside will rise, the boiling point will rise, and the 'cold side' temperature will rise - which massively raises the cost of the cooler (and still degrades over time, just more slowly). Or the working fluid needs to be switched to one with a near-ambient boiling point (e.g. one of the Novecs), which also massively increases the cost of the cooler. Reply

To solve that, you could just use a check valve at the top of the radiator. Gas comes in, gas goes out. Very simple. Reply
