So I am confused?
Specs are 800RPM and 65.3 CFM
But they show a pretty chart chowing starting at 70CFM and going up to 130 CFM.

Reviewers are saying it pushes a lot of air and at 170mm 65CFM is not a lot of air, My silent X 120mm pushes 120CFM at 19db

Their website claims that it is 800RPM max with 65 CFM.

Does this go higher than 800 RPM? know if the 65CFM is truly it's maximum?

Accepted Answer

You would average between 65-80cfm but the point is that it is able to push that much air at 18db and only at 800rpm, which means you get more air per rpm. Most of the reviews I have seen for SilenX fans say that the 18db is misleading and that the sound is horrible (which if it went up to 1400rpm then it would be unbearable). Maybe you have a better fan or you are use to the sound, but I venture to say if you went to the XigmaTek fan it would be a lot quieter.
