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.
