Hey guys,

As you all know by now, we produce a lot of cases and coolers and power supplies, and those things all use fans. So I've decided to do an unofficial poll and ask you guys about fans.

I'm using RPMs above, and for the meantime, let's assume they're all non ball-bearing 120mm fans. I know that this isn't the best way, but in our extensive testing, noise levels scale with RPM, and even among 20-30 different fan designs, the noise level difference at the same RPM isn't massive (unless you pick a few really, really bad outliers whom I will not name).

Feel free to post your thoughts.

I'm just trying to get an idea of where you think the top end is, from an acceptable RPM standpoint.

This is tough, because what you define as "medium hum" and what I define as "medium hum" could be completely different.

Why is there not an option for "Nothing is too loud."

anything that's louder than a kaze at 2200RPM is too loud already.

sounds are different from each fan , its hard to say what rpm is to loud. as one fan at one rpm is more quiet than another fan at same rpm.

It depends greatly on the application of the fan...
I know for servers I used to deal with at work, they were quite loud, but it was an acceptable, and homey hum/whine... And my home server, the fans are quite loud too, but that's acceptable since it's a server, and servers aren't supposed to be quiet.

HTPC's on the other hand, should be quite quiet..

I'd really just love to have a fan that moves a mega ass-ton of air, while being quiet, and cheap (much like the Zalman F3's, but quieter, and more air)

Other - My fan is currently at 3200rpm and it doesnt bother me although I do hear it a bit. Id say 3500rpm
post #10 of 78
It naturally varies from fan to fan and application to application, but 1700rpm or so is about the maximum I personally find tolerable for daily use.
