So most case fans base their measurements of airflow on CFM. But I noticed that noctua quantifies airflow with c^3/h. Is this the same measurement? It makes me not want to buy from them because I am worried that it is actually weaker than what they want you to think. Also, are noctua fans as quiet as this video makes it out to be? The one I am looking at is the NF-B9 PWM. Thank you. http://www.youtube.com/watch?v=gqp6BxxqlC8
Noctua fans are purported to be among (if not) the quietest fans out. From what I have read and seen, they are among the best overall - six year warranty on a fan is rare. I've just never been able to justify the cost myself or I'd probably have them hanging all over my builds.
I've been looking at that, not unexpected to list cubic meters/h (M^3/h) since they are an Austrian company... the numbers seem to be okay, let's see if I'm doing it right. 64.3 meters per hour divided by 60 = 1.07 cubic meters per minute times 35.31 cubic feet per cubic meter gives me 37.7 cubic feet per minute (cfm). I guess that's not bad for a quiet fan.
Thanks. I had a feeling that they were using those numbers to make is seem like it had higher airflow than it really did. Do you have any other suggestions for good 92/120mm case fans that are relatively quiet?
For air and case cooling I would say the Cougar fans have the Corsair fans beat, more airflow, quieter rating... my interest in the Corsairs are more appropriate for radiator applications - since you started this thread, I've been considering replacing my ultra-kazes from my rad since they are by far the loudest ambient noise makers in the house - I hadn't noticed it much before.
