Unless you are completely fanless (and you live in the middle of nowhere with no traffic near and you are not running any kind of appliances not separated by some thick walls near you) a fanless PSU is a bit of a waste of money.
Even with all my cooling fans going ~800 RPM (which is virtually silent) they still make more noise than my HX550.
Luckily not many cars pass by my window (it's at groud level and facing the street), but since I started to listen to music from the PC, noise has been an issue.
Then again, I only have this problem when I'm listening alone - when it's really quiet.
I use a whimsy passively cooled, 8600GT, and the Big Shuriken CPU cooler is undetectable even if I put my ear next to it. There is one 120mm case fan (silent). My case is an Antec P120, and the only thing I hear is the air passing through the PSU and when I stop its fan, the PC is dead silent.
Yes, I can't hear it if medium loud music is playing, but sometimes I turn the volume way down, and then it is almost as loud as the music.
I find lowering the volume easier on my ears after long listening periods. Maybe it's just due to the slight hearing damage I got from working in a metal working factory during summer (and being to dumb to protect my ears) and too loud music in concerts.
I've only ever had two PSUs die, and they were both Enermax, and went with a bang less than two years old. There were both in different machines in different homes, and since then I've stayed away from Enermax, with Corsair being my favoured choice. Maybe Corsair don't build their own, but at least they make a point of only putting their name on quality parts.
The Modul87 line seems to be some new construction, I hope it's durable - at least it's efficient, and according to the review the fan wouldn't change from minimum RPM at the power loads in my PC.
