Before anyone says anything about this being a fan and it should be posted in the air cooling forum, they are designed for watercooling so they are in here
Just received an email from Specialtech about these new fans from Feser designed for watercooling.
Oh yeah and very expensive!
Here is the image with the blurb and also the link directly to the site
The dudes voice on that site is gonna seriously get on your **** very quickly!
They claim for the low speed fans (1200 RPM) - 21DB / 61.6CFM
For the medium speed fans (1800 RPM) - 30DB / 88.4CFM
Both with high static pressure. They also reckon operating voltage up to 13.5V.
