Corsair CO-9050043-WW ML Series ML120 Pro LED 120 mm Low Noise High Pressure Premium Magnetic Levitation LED Fan - Black/Blue

ML120 PRO and ML140 PRO Very 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.

Great good quality product as you can expect from Corsair. I have used their older generation fans when specifying my gaming PC last year with the two different variants the static pressure and airflow types. This is done away with in this design and it is effectively an all in one fan combining the air flow and static pressure into one product with all different colours etc.One thing to keep in mind when considering this product is that it needs a 4 pin fan output on your motherboard or fan controller not the usual 3 pin this is because there is a consistent 12 volts fed to the fan and the motherboard/fan controller tells it how fast to spin. The advantage of this is if you get an LED version the LED's do not dim/brighten as the speed decreases/increases. The magnetic levitation technology means there are no traditional ball bearings in this fan so reduces drag and noise which helps in two ways. 1) The fan has a higher RPM than regular fans which means better cooling (very helpful in summer). 2) Less noise which if you have up to 7 of these in your case it will make a big difference to the sound your gaming rig generates as 7 fans producing 40dB each does not mean that your system makes 40dB its more nearer 50dB. Overall if I was building a new gaming rig these are the fans I would use and with a 5 year guarantee you cannot go wrong! Also a recommendation get a fan controller so you can extract the full potential and make sure it has a 4 pin output for all fans.

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.

The 140ML Pro shifts plenty of air, and that's the main atribute I was looking for as an exhaust fan. Looks wise, of course the colour is subjective (I went for red). They do look good and are made well enough. The only downside I've found is that the LED does dim through PWM use. No big deal as it's still a decent colour, but it's stronger under more rpm. Noise wise...This can depend on your case. In my Fractal R5 when above 60% speed, it can be quite noisy. But the mesh grill in my case is what is causing the noise...Not the fan itself. All in all a good fan. If you're not too overwhelmed by the actual design, and you're not too happy about the price then there may be something better looking for less money that will operate much the same. The cost for me ensured plenty of reliable movement of air. The looks are seondary to that, but as a bonus I do like the look a lot.

These new ML fans from Corsair are an impressive leap in quality and performance over their previous generation (AF and SP) fans. First, they are significantly heftier, a much denser, better build to them decreases rattle and gives a premium feel - especially on the blades, too. I picked the black bladed style with no LEDs and it looks exactly how I want it to - understated and practically invisible in a dimly lit case. Not everyone needs a light show to game. These fans feature a new magnetic levitation bearing as opposed to a traditional ball bearing design, the new 4-pin PWM socket pulls a constant 12v for the magnets while also allowing the fan to spin from a range of 400 to 1200 RPM. They have an incredible 5 year warranty, obviously corsair has confidence in their new fans. They are also not splitting the product stack - there are no SP or AF variants this time - only ML, the ML fans are capable at both static pressure and quiet air flow and boast significant performance increases with volume of air moved and pressure of the air moved - all while being whisper quiet, if that's what you want.

Having replaced my motherboard, CPU and Graphics Card recently (now have Z370P, i7 8700 and RTX 2060 OC) I found my old 120mm fans (3 pin) that came with the case were struggling to shift the air and were noisy. I replaced the two of them with these 4 pin PWM models and now have an almost silent PC with lower CPU, motherboard and GPU temps. These things are as silent at 1000 RPM as my old fans were at 400RPM. Admittedly, at 2600 RPM they sound like an aircraft taking off, however with the setup I've got they don't need to go over 1500 rpm even at full load. Below 40 degrees I run them and my CPU fan at 900 RPM ... watching 4K video and the temps stay at around 30 degrees for motherboard CPU and GPU. Highly recommended.

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!

Corsair ML140 Blue LED: I bought these recently after much research into variousoptions, which eventually culminated in a need for 4-pin (PWM control) fans to get the most out of the fan control from my new motherboard. The older Corsairs (SP, AF series) were great, but they are all 3-pin models, and use an older design of sleeve bearings. I wanted ball bearings, preferably dual ball bearing, for noise and life expectancy reasons. Options are limited for shipping to Ireland, so in the end I ended up with two main options, either the Noctua Chromax (black) versions (I hate that brown colour scheme), or these. I went with these due to Noctua not providing LED options. While these fans produce good airflow, they do have a deep hum that, while I'm not very sensitive to it, could drive other people crazy. Of the two options, the Noctua's produce less noise overall (from what I found online). Another thing I noticed is that Corsair don't seem to publish their life expectancy estimates for their fans, which Noctua do. I do love the Corsair's blue LEDs, they're not very bright, but the are eye catching and work well in my tempered glass case. Their lighting saturates the fan blades quite nicely. The fans themselves have no special grooves or anything in the fins, their 4-pin cables are not great quality but are a decent length, and the rubber shrouds for vibration dampening are not great (they cover a very small area - its the bright grey areas next to the blue corners, not the blue corners themselves). They also come with standard screws, not anti-vribration rubber ones I'm certain you get on the Noctuas. While I'm happy enough with these fans, I don't think their pricing is justified, and I would suggest getting the non-pro editions that sell in dual-packs for better cost-benefit. Those have no vibration dampening pads, but you could buy your own rubber fan mounting 'surrounds' to overcome this which would probably work better than the dampening on these pro versions given the contact area. If LEDs are not your thing, or if your case has no windows or tempered glass to see them anyway, then go for brown Noctuas. A side note: be very careful about running these magnetic bearing fans with manual voltage control - this reduces their lifespan greatly. The fan's bearings need constant full voltage (PWM control on your motherboard does this), so running them off a fan controller on your case will cause problems unless it has proper PWM control (and not voltage control).
