Best in Class
I bought a bunch of fans, including a Noctua and an Arctic P14 Max for consideration.This one was by far the best, with the most mounting options (saved my bacon on a tight clearance bay), the best quality (cable wraps, manufacturing tolerances, etc), and a very low noise floor. Moves great air for the RPM. Easy to install. Kind of expensive but worth it.

Amazing 140mm fans
Why did you pick this product vs others?:Very good fans that push a ton of air while being extremely silent I love the look as well. They do cost a bit more than some other fans but you definitely get what you pay for and the added performance and noise is well worth it to me I would recommend anyone replace their cheap/lous fans with these are pure quality

High quality and very flexible for different uses in your case or CPU cooler.
Quiet and configurable. All you could want in a fan. These come with a variety of installation options through different corner attachments and installation screws or vibration reducing padded pins. Very well thought out system that can fit just about anywhere in your case that the fan will fit and can get power.The packaging feels and looks premium and the fans easily last for years in my experience. I look forward to reusing some of these in my next build in the late 2020s.

Silent most of the time, but capable of moving air when needed.
Love these fans. Nice and quiet when they need to be, but they can get loud if cooling becomes more important. Set your fan curves a forget it.

Great fans, new set for my bigger case.
Great fans, I needed more fans for my new case, and I already have this brand in. I wanted to control the speed of my fans to make the system quiet, and these really are quiet at 900 rpm. The cooling performance doesn't seem to be affected by running the fans this slow, and of course you can change the curves to make them go crazy if the system really needs it. Kind of pricey fans, but they work as advertised.

Don't hesitate
BeQuiet are the only fans I'll ever buy. Great airflow, quiet and solid! A little pricey but you get what you pay for.

Run on middle setting
Moves a lot of air on the normal setting. Using the high performance mode on these fans sounds rather loud. I don’t know how much use you would get out of the selectable fan speed.
