Corsair ML140, 140mm Premium Magnetic Levitation Fan (2-Pack)

Summary: Both of these are great fans that I highly recommend. The Noctua NF-P12 redux is cheaper and quieter then the Corsair ML120, so it is best for most situations. The Corsair ML120 is great when you need a fan that can run both quiet or loud and powerful. It can run 700 rpm faster than the Noctua so it is a good value for a such a powerful fan, but it is slightly louder at the same rpm and a couple of dollars more expensive then the Noctua.Noise: The both fans are silent up to 1300 rpm. The Corsair ML120 is slightly louder than the Noctua NF-P12 redux at speeds above 1300 rpm. I was really surprised that the Noctua NF-P12 redux beat the Corsair ML120 on noise, as the ML120 uses a magnetic levitation barring, but I guess that Noctua’s fluid barring is just that good.AirFlow: The Corsair ML120 can run up to 2400 rpm while the Noctua NF-P12 redux can only reach 1700rpm, so the ML120 is capable of more air flow and higher pressure then the NF-P12 redux, although Corsair ML120 is quite loud at max speed.Static pressure from spec sheets: Corsair ML120 up to 4.2 mm-H2O, Noctua NF-P12 redux up to 2,83 mm-H2O.RPM range: ML120 = 400-2400, NF-P12 redux = 450-1700. The main advantage that the Corsair ML120 has over the Noctua is that it can run 700 rpm faster. This is great for a situation where you might need some extra cooling power at the top of a pmw fan curve.Warranty: ML120 = 5 years, NF-P12 redux = 6 years. Both of these fans have top quality bearings, so they should both last for many years unless you get a defective one.Accessories: As these are both basic models they do not come with anti-vibration pads or any other accessories other then mounting screws.Price: At the time of this review a 2 pack of ML120 was 31.41, so a ML120 was $15.71 while a NF-P12 redux was $13.90, so the Noctua is a couple of dollars cheaper, but the ML120 is still a great value for a good quality 2400 rpm fan.Note on product models: The performance of the ML120 is the same as the ML120 PRO, the PRO model is just a more premium variant that has anti vibration pads, looks better.

My old fans started to fail after about six years of use. I figured they were going to be needing replaced soon. I decided on these because of the they were four pin and had no rgb lighting on them. Made then perfect candidates for my build. The airflow of these fans are magnificent even after a few months of running them now. I will have to clean them soon in about a month or two now but they have been running like a champ ever since they were installed. The noise is a bit much but expected since I have one plugged into my water pump and is full throttle when being ran. Though the noise is bearable and not even noticeable on a microphone or when wearing headphones, so works nicely for my use. If you are looking for build quality I give it a hard five stars because the plastic they use isnt cheap feeling or soft plastic. The plastic is hard and doesn't bend very well making them durable for any build. I would recommend these fans to any of friends that are in need of a cheap but very nice build quality, with amazing are flow fans for there builds.

Preamble: I have almost zero experience fiddling around in the guts of a computer. My dad built PCs as a hobby but I never really watched him and he never taught me anything. Keeping that in mind, here's the review of the plain, not-light-up twinpack from the PoV of a novice.- Good, sturdy, heavy plastic. These things feel really sturdy right out of the box.- The box itself was really sturdy too, and they were packed real tightly and well.- 4-pin connectors. I'm putting this here because it does not say anywhere that they are 4-pin and that's kind of important to know.- Put the 'pretty' side out--the side where the centre just has the corsair logo is the side that goes 'out'. I just looked at how my old fans were orientated in my tower and put these fans the same direction, but I know folks aren't always *replacing* fans. The logo side sucks, the side with the words on it blows.- The bolts that come with are very short, and are meant to go in backwards, which is why they're not very long. This can be a huge issue if you can't get to the back of the fans, where they press against the frame of your tower. I happened to have the great good fortune of my old fans' plastic pins fitting these new fans just fine, so I used those instead of the bolts that came with the new fans.- They are, indeed, silent. The only noise you hear is literally the air going through them.- They are grey-bladed. The single pack of not-light-up has the black blades. I happen to think the grey blades are better because they won't look dirty as quickly and that's a plus for my finicky a$$ lol.- They don't light up!! Thank GODS, I *hated* the glaring LED lights of my factory fans, esp because they were Macho Gamer Red™ When I turn out the lights to watch a movie or play Dragon Age, I don't want all these glaring red lights ruining the atmosphere and distracting my periphery!- AND FINALLY: Absolutely plug-and-play for those of us who have no idea what 'overclocking' is, and just want fans that do their job.The fans that came with my PoS tower crapped out on me after a couple years, and were sleeve-bearing fans. They lasted longer than they should have because I would oil them frequently, which is messy and awful, but they limped along until I could save up for these. These are magnet bearing, which are the highest quality of bearing (I did a lot of research and sifted through LOTS of technobabble to figure this out, which is why I want to share it here in plain words so people like me who aren't gearheads can understand). Magnet bearings don't need oiling, afaik, so I'm looking forward to that. I'll update this review after a year or if something goes wrong.
