Nice, though. Papst fans have been in development for 20 years, while this type of case fan might have a way to go before being as silent as the form factor would allow. Antec sells a Cyclone Blower
that is a very similar design, with 42 CFM / 26 dba. Of course, that number might be 1 inch away, it might be down the hall, they don't say. But, unlike the silentpc.nl fan, the cyclone blower is actually for sale, and goes for as little as 10 dollars. Who knows how loud it would be at 7v?
What is up with the name cyclone blower? Aren't they touting this as a silent fan?[/url]
That number is from down the hall. I had one of those - the first thing I got rid of, and it made a big difference. I seriously thing they reversed their DBAs and CFMs. 26 CFM @ 42 dba sounds much closer to the actual spec. Undervolting doesn't do much unfortunately.
PCP&P's Silencer is at least better than Panaflo if 7-volted although you won't be able to get 20CFM out of it then. There are also some less well-known cheap fans, usually made in China, that are good if undervolted, but I don't think they are available in Europe. Sometimes you can find such a fan inside a cheap PSU, like Codegen's.
Really? Cool. I just ordered 3 PC Power & Cooling silencers. They should be here on Monday.
Right now I am using seriously undervolted loud fans (50 dba @ 12v - 25? dba @ 3 v)
