My case has a radiator up top in which I am using 3 Cougar CF-V12HP's (120's) as exhaust.
Ever since I got them they had been louder than I expected so I dampened some of the noise by taping some steel washers in the middle (no I'm not slowing the blade), I can use more weight to make them virtually silent (again, not slowing the blades) but I felt this was a <removed by moderator> solution to a problem that the manufacturer should deal with.
So I emailed the manufacturer and attached a picture of my setup:

They responded:
Does this sound like <removed by moderator> or what? I asked what type of fans they could recommend and they responded:
So, I ask here then, what type of fans could I use to get some silent exhaust performance? Whats the point of water cooling otherwise...
Thank you

Hi,
The CFV-xxx fans are not recommended to be mounted horizontally blowing air up.
Blowing air down is preferable.

We don’t know of any particular type that could sustain mounted in that position. Guess there is a tradeoff in cost/performance.
For service of end-users we are limited to exchange of identical product as we are not set up for monetary transactions. You could still send them in for exchange for a set of new ones if you wish by filling out the attached RMA Form.
