be quiet! Silent Wings Pro 4 140mm PWM High Speed 2400 RPM Premium Low Noise Cooling Fan | 4-Pin | BL099

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.

The Be Quiet fans are some of the most solid and rigid fans I have seen. They ae much heavier, and extremely quiet fans while moving a lot of air. I am using these for replacement radiator fans and they move much more air with higher static pressure than the original AIO 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

Be Quiet! has become one of the best fan companies for PC building, they may be a bit more expensive but the quality and air flow they provide is top notch.I personally purchased 4 of these for my gaming PC, and it made a huge difference in temps compared to the stock fans on my Fractal Torrent case.They run at a good speed of up to 2400 rpm and make a lot less noise compared to the stock fans I had.The airflow in my case is great with these fans installed on both the exhaust, and bottom intake.Will be my go-to fan company for years to come if the quality and performance stays top notch.Thanks again Be Quiet!

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.

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, 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.

These fans are awesome! I'm aircooling a 7800x3d so airflow is super important to me. I mainly wanted to replace my stock case fans bc they had white fans and I wanted an all black pc. So I finally got around to installing these. I removed old fans and ripped out all the ridiculous rgb they came with, whew! Finally. I despise rgb. After installing these, I had to keep looking to make certain they were actually spinning since I couldn't hear them. Long story short, improved performance, near silent, no rgb! Yes! Very happy.
