Antec 761345-75120-9 3-Speed Case Cooling Fan

Pros: Quiet to a extent. Has switch for RPM speeds! Pushes LOTS of air at max RPM but very loud. Middle setting is sweet spot.

Cons: Extremely loud at 100% full go. Not as quiet as I wish

Overall Review: It works nicely, I might buy another.

Pros: They work

Cons: Bottom setting doesn't get quiet enough for the amount of air it moves. It's only doing 39CFM, but it is still an easily audible 25dba. There are a lot of 40+CFM fans that are in the 15-20dba range.

So basically it kind of defeats the purpose of the 3 speeds because none of them are silent. You basically end up with a jet turbine setting, a not that quiet low airflow mode or the middle which is kind of like an ordinary case fan the is not that quiet but moves good amounts of air. Most people will just end up parking it on the M setting.

Overall Review: If I had to do it over, I would just pick some single speed fans to match my noise/airflow requirements. These seem to trade off a lot of that in exchange for the switch. In the end, not a very good bang for the buck.
