    Customers like the noise level of the electronic component fan. They mention that it has no motor noise, is dead silent at low RPM, and makes a chirping noise above 600 RPM. The fan itself makes no sound other than the air it's moving, which sounds nice and non invasive.

    A highly recommended beast with only a few drawbacks
    So, I read the reviews before I got this (Corsair ML120 Pro LED, White, 120mm Premium Magnetic Levitation Cooling Fan (CO-9050041-WW)). I just built a pc and my stock case fans are atrocious and it's making everything in my case moody. I'm a huge Corsair fan (despite my problems with the quality of some of their headsets) and I'm not super into RGB. It seemed like fate that I would find an LED only maglev fan. AND BOY IT WORKS.This fan is rated for something like 2400rpm, right? I easily get 2600+. I've been keeping it on full speed since I installed it and the only drawback for that is that at full speed, there is a whirring/whining noise. If you like having a room fan, it's not so bad. If you've ever had a PS4 pull a jet engine on you, it's pretty similar. With a headset on it really isn't noticeable and I think it honestly moves more air than my room fan does... But I think at around 80% is where the noise kicks in. And for as much work as this fan does, I'm honestly not going to be picky. It might even actually choke the airflow in your case if you put it at the back without having strong enough front/top fans or a case with good enough airflow. Which is why I'm now buying another 6 of these.That being said, I had read a review that said something about the screws and installing this fan was going to be a pain. So I was prepared for that. And he was absolutely correct. The holes for the screws aren't threaded. So you WILL get some resistance and you WILL get some plastic shavings. I'm a little concerned that at some point, if you adjust it a lot, it will eventually become stripped on the actual fan casing. And as a side note, installing it DID chip the paint on my case. I have a Cooler Master Masterbox TD500 Mesh White and as it was pretty cheap, I wasn't expecting the greatest quality (it came to me with a bad front panel), but with the fan installed securely and not forcing the screws, it still chipped it. So there's that.Also, the cord to connect the fan to your controller or motherboard isn't the longest. It was a bit difficult for me to connect mine and not have a giant cord running right across my GPU and CPU fan.However, you will most likely fall in love with this fan and proceed to replace all of your fans with it. It is beautiful and a workhorse. You will be disappointed in every other fan you come across because they don't have the same air movement or style. 9/10, would attempt to build an airplane with a couple thousand of these.

    When I first read reviews about the GE Force RTX 3080ti, which, in my case, came packed with 84 degrees Celsius at stock, I was considering building a custom loop to cool down the GPU. I instead resorted to these fans (4) plus the Corsair's Capellix AIO (in addition to some tweaks to the GPU itself, which lowered the GPU temps by 30 degrees Celsius). I tested these fans at OC temps (CPU @ 5.2Ghz and GPU @ 2100+ Mhz) to see if the fans would help and they do provide the required cooling within the case, as long as you have very (!!) good air flow. Remember that fans, or an AIO - alone - won't cool down a system which is unreasonably high, however. . . >> you'll need to manage those components with careful testing to get the max out of the CPU / GPU with minimum voltage and wattage, first. There are good testing tools out there to help you calculate the flow of electricity and watts' usage at any given second and modify the CPU / GPU behavior w/out losing stability and actually even increasing efficiency and output. But when you have those occasional spikes in temperature within your case, these fans will kick in and provide the relief needed to avoid an unwanted system crashes. These fans are silent, have a really easy-to-use software (use it!) and the light show is amazing. I play on demanding simulators pushed to their limits and need all the quick cooling-down capabilities that I can possibly get. I have purchased more of these fans for a second PC with an RTX 3090. I am not considering fans from any other company.

    Being very sensitive to noises, I went through almost all of the highly rated and recommended fans throughout many years. I used to have Gentle Typhoons (AP-15) on my 480mm and 240mm radiators, and although they did their job well, the motor noise was starting to get on my nerves. After discovering a leak in one of the rads, I decided to upgrade my entire setup.

    I initially ordered the Corsair SP120 Performance Editions, but when placed horizontally on the radiator it would emit a rattling sound which really got on my nerves. So I returned them back to Amazon and ordered the newer Gentle Typhoon PWM editions to only find out the motor sound was worse than ever even on low RPM.

    At this point I was just frustrated, so even though the ML series was quite new, was costly, and didn't have as much reviews, I decided to give them a try, and I think these are the best fans I've heard so far. There's literally no motor noise due to Magnetic Levitation, and the RPM curve via PWM is smoothest I've seen yet.

    Keep in mind that these fans MUST BE controlled via PWM (either a controller, or from your motherboard PWM header). Not using PWM will run these at full speed, which will be quite loud. Controlling these via DC can work, but is not recommended as the range, and RPM curve will not be as smooth, which can produce unwanted noise.

    Pros:

    - Excellent RPM/noise curve
    - Barely audible at lower RPM
    - Build quality is superb
    - Flat, sleeved cables
    - Rubber on the contact points to reduce vibrations
    - Looks sleek aesthetically
    - Pushes more air at lower noise levels
    - 5 year warranty from a company I consider the best at customer service and warranty replacement

    Cons:

    - Expensive. Although there are fans that perform better at lower cost (though at the cost of noise), I feel that it's totally worth it if you're sensitive to the motor noise like I am.

    I am normally a noctua die hard but I decided to try these this time around. At full speed these things sound like a jet engine taking off. They move a tonne of air but at the expense of your ears. I would not recommended these if you want any sort of quiet environment unless you run them at 1/3 speed.
