Corsair CO-9050042WW ML120 120 mm PRO LED Magnetic Fan - Red

ML120 PRO and ML140 PROVery high quality fans. I have bought about 15 of these now. Their main strength is the exceptional range of speeds they will run at. The 120mm runs 400-2400 RPM. The 140mm runs 400-2000 RPM. They generate very high pressure levels so are perfect for coolers and radiators but can also be used as case fans. The fans are solid and heavy. They inspire confidence with the obvious quality of build. They are supplied with four black screws.These are very quiet fans. However, they can turn at very high RPM so the “woosh of air” can be significant. They are pretty much silent up to about 1100-1200 RPM, but beyond that you can hear the air moving. At 2000-2400 RPM the amount of air moving is loud. Most people will not want that level of RPM. What I do is control them up to around 1000/1200 RPM for normal cooling then ramp them up to higher levels for emergency cooling only. There is no bearing noise at all. No clicking. Nothing. Just air!At 50% these are developing twice the pressure that a Scythe Mugen cooler fan does at full speed. Comparing to Noctua, they have a very similar performance in both noise and pressure, but offer higher RPM so more flexibility. Don't listen to the nay-sayers who are just running them flat out and expecting them to be silent. Having said that, you do need to take control of the fans to ensure you get the right cooling to noise balance. Most BIOS' these days allow you to control the speed or applications like iCEU.Because of the high RPM and high pressure these are better suited to use as a replacement fan on a heatsink or AIO. In fact these are the fans provided as standard on Corsair top of the range water coolers. I use them for everything, including case fans ( These are four pin fans not three pin so you need to check your headers. ).Please note that the Dual Pack of fans are the standard ML fans not the ML PRO.They are a bit expensive, yes, but they are very good.

I know what you might be thinking... Magnetic Levitation fans?! Has to be a load of marketing rubbish... right? You are probably also considering these because you want them to do two main things: 1) Shift a load of air 2) be pretty quiet about doing it.Well, it probably is a little marketing rubbish, but there's no denying that whatever wizardry Corsair put in these fans, they are rather effective at doing what they do.Case fans now come in two flavours now-a-days... high air flow, meaning they are more efficient at shifting high volumes of air in open space and high static pressure, meaning they push air through things like radiators and filters better.I like my computer to be whisper quiet. It already was pretty quiet but the fans on my water cooler (Corsair SP120s) although high static pressure fans were a little noisier than I liked, even at lower RPMs. My intake/exhaust fans weren't really the right fans for the job either since they were high air flow Fractal R2s and I have filters on all the intakes and exhausts on the case (I don't like dust!).I connected up all the fans like for like and set them to run at the same RPM as used with the old fans. Not only is it now quite noticeably quieter (at idle/in Windows, I can actually hear the hard drives over the fans) but average temperatures are a good 5c lower too (I suspect mainly due to better air flow through the case).In all, it seems they are just as good as the non-Magnetic Levitation high static pressure fans, but they are quieter in doing so. There isn't a huge difference in price between the two either, if you aren't bothered about fancy LEDs in everything!

I bought this case fan to remove more heat from the PC than a standard 1200rpm fan - and it does! Sturdy and no vibration at all on full power. At 2400rpm its quite loud but what do you expect at that speed. My case temps are cooler than before and I run the fan via a Bitfenix Recon at 1600-2000rpm. Nice crisp white LEDs too!

These fans turned out to be good. Set fan speed to 40% and they are just about silent. At full power they are very noisy but they also move a lot of air.

There's no getting around it, these are very expensive fans. Kitting your rig with 4 of these to replace stock fans is a cool 100£.. good luck explaining that to your wife.But as long as you manage your expectations, then i think these could be worth it.1) Looks: I think they look great. PWM means they'll constantly be supplied with 12V so they'll keep their brightness even when you lower their rpm. Some led fans are 3 pins and would dim when you do so. The construction is also pretty sturdy.2) Cooling and noise: If you already had good quality fans (in the say 11£-15£ range), then you won't really notice decreases in temps. What they do have however is a pretty large rpm range, so you can lower them to inaudible levels, and crank them up all the way to 1800 rpm if you need to. That flexibility is pretty neat. Some fans would also rattle at low rpms, but these so far remain silent.Overall if you had crap and noisy fans then these would be a very worthwhile upgrade. If you already own good fans then it's a more difficult choice as these aren't cheap, and you'll have to decide whether the looks and build quality is worth it.

Awesome quality and looks great. Does the job well

Hacen mucho ruido, pero avientan mucho aire, asegura de configurarlos de tal manera que solo se enciendan cuando realmente se necesitan, de verdad hacen mucho ruido, yo como tengo la pc al lado del monitor me resulta molesto el ruido, asi que tuve que apagarlos y poner que se activen solo cuando la temperatura del pc sube tales grados. Pero si quieres ventilacion, estos son los que mas ventilan en el mercado, de los que encontre. como 73 de flujo de aire tienen.

Melhorou a temperatura do meu gabinete e não tem muito barulho

Es un muy bien ventilador para radiador, lo compre para hacer push pull en mi corsair h150i elite capellix, la única diferencia con los ventiladores de esa aio es el RGB pero tiene el mismo desempeño que los ventiladores de la elite capellix

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.

The media could not be loaded.  Baixou minha temperatura (tempo de seca com temperaturas médias de 37° C) de até 90° C na GPU para aceitáveis 70° C. Produto excelente.
