"One interesting characteristic we found was that fan speeds make very little difference - in this instance, only a C/W of 0.01 between running the fans at 12 volts and 4.3 volts; at 4.3 volts, there is almost no noise from the fans. I've seen this before in heatpipes - an example HERE."

1305 rpm, <50 dBA², 0.15C/W - thermo syphon
1960 rpm, 51 dBA², 0.13C/W - XP90C

Id hazard a guess at 1300 rpm that they could very well be a close match...

It would be interesting to see the 4v shrouded test, and the XP90 shrouded to the side panel intel prescott spec fan shroud/rear of the case.
