Of course I did. I reed every single review, news availabe about fanless psu's on the market. I've figured out there's no way running a fanless PSU without sufficient airflow in your case. I've also personally experienced it with Magnum by removing its fan. It simply didn't work. The prerequisite of having sufficent air cooling inorder to run a fanless psu sounds totally ridiculous. There's no way you can provide sufficient air flow at death silence:( This is why I don't see a totally fanless psu as an option.Good man. I have exactly the same goal. For true 0dB performance, have you considered any other fanless PSU's, ie Antec Phantom, Silverstone ST30NF, FSP Zen etc
But incase you have every material heat source (CPU,GPU,NB,HDD) watercooled (passively), then a semi fanless design such as silentmaxx 450 watt (rated as 12db max) should work perfectly without need of any case fans. I use an Innovatek Konvect-O-Matic Ultra for passively cooling these components. If I had a fanless PSU, there would be no audiable noise@1m in my system.
I'm sure every silent pc enthusiast has heard about it. This design should work flawlessly aswell:

I'll be the first one to buy it when it becomes available
As for watercooling PSU's, Silentmaxx tried it but it had reliability problems and probably it is discontinued.(No information can be found at their website about the Prosilence Watercooled 450 Watt) I think they were simply cooked because waterblocks were attached only outside of the PSU. Another German brand, Nc-Silence tried watercooling a PSU too. Also Innovatek has modified an Engelking 300 Watt for watercooling but they have discontinued producing it aswell. They all had very similar designs. None of them had the waterblocks inside the PSU and this is the reason of their failure. Of cource it is a bit scary to have water inside a PSU, but this modified Enermax seems provide extremely efficient water cooling:

I wouldn't hesitate to buy one of these If they were a bit cheaper...
