A six-pole fan motor with three phases for low power consumption and reduced vibration produces maximum noise levels of 28.1 dBA.
IC Motor Contoller
A high-quality IC motor controller helps reduce electrical noise.
Pulse-Width Modulation Functionality
Pulse-Width Modulation (PWM) allows all compatible 4-pin controllers, including those built into many motherboards, to intelligently vary the speed of the fan.
Surface-Optimized Fan Blades
Seven fan blades with an optimized surface structure helps to ensure virtually inaudible operations and a strong airflow.
Anti-Vibration Mountings
Removable anti-vibration mountings on all four edges of the fan help to reduce vibrations transmitted to the system case.

Totally worth it!

I like these fans, but honestly, I don't have a lot of experience with fans. However, these fans come with complete and different options for mounting. I think they are quiet, but I'm deaf in one ear and can't hear well in the other. They run really smooth and are vibration free.

Well built and quiet

I ordered this fan because it match with the the theme I was going with on my PC build. And let me tell you this that these fans are really quite as the name itself implies. They quite also effective when providing the cooling air for the pc and thrusting out the heat out the pc with quite an ease. If you are making a pc might I suggest the pc case for these fan is be quiet! Pure Base 600 Mid-Tower Case ( Black).

Powerful and Silent

They are quiet (virtually inaudible) in standard operations, and if you need to push performance to a pick they will move a ton of air cooling the system as none other. The best fans I have used till this day.

Great if you are using a be quiet case.

I would normally prefer Noctua, but be quiet is in the same league.

Nice quiet fan.

Well built. Very quiet. It does not have RGB built in, but I use Phanteks RGB frames on them, and although they don't reflect colored light as well as white fans, they do look very nice.

Quiet for the airflow it provides

I acquired this in an attempt to have an NZXT H1 V2 build be a tad quieter under load. Replaced the stock 140mm fan with this one, it definitely seems to have had an iterative positive effect on noise without sacrificing heat management. I haven't done a head-to-head between this and the Noctua 140mm offering. I have a lot of experience with Noctua's fan quality but wanted to give this one a shot. Happy with it. I may grab a Noctua 140mm just to do a head to head. At this point the GPU fans are 100% the limiting factor in the dbA output of this system under load. Undervolting solved a little of that.

Quality fans.
