Cooler MasterMasterFan MF140 Halo Fan, Duo-Ring ARGB Customizable Lighting, 140mm PWM Static Pressure, ARGB Header Extender For PC Case, Liquid and Air Cooler (MFL-B4DN-15NPA-R1),Black

The media could not be loaded. These fans work great as top exhaust fans in my build.The push a great amount of air, and I love the addressable lighting. You can set it to a single color or to react to your games or music or desktop color scheme. Or you can set them to go crazy in rainbow or other such effects as well.To get these setup is a little bit of a hassle as you have to connect 2 cables per fan, each ones has a power and lighting cable. You can daisy chain them together to take up less fan headers, and also daisy chain the RGB cables and then use a single ARGB header on the motherboard for lighting. Then you can control the lighting using a program like Aura on my Asus motherboard or others.Alternatively, you can use the included physical controller, but then you need to open the case or have it setup to hand out of the back of your case somehow to use the physical controller, so I chose the motherboard route of hooking everything up.The fans are a little louder than other fans in my case since they are 120mm and being used as top exhaust fans which are closest to be heard on the case and the intake fans are all 140mm and less loud. But it is not super loud or any weird noise, just air moving which cannot be heard while gaming at all.

Bought these for my new build in a Corsair 4000D Airflow case. Bought the 3 pack plus a single unit. 3 fans for the front intake, one in back for exhaust. The "halo" on these make them standout against competitors from a looks standpoint, and the price point is reasonable also. I get that they aren't rated as high for airflow as some other fans, and some people prefer a full box design to the fan case. But, I'm just running an i3-10100 and a 1050Ti GPU, so I don't expect a ton of heat generation, and the new case is fantastic for airflow.I have all for fans daisy-chained, so the design of the leads for the fans works great. Yes, the leads reach from the back of the case to the front, so no extension sables are necessary. I have them plugged into the ARGB header towards the top front of my ASRock mobo. Cable management isn't an issue. I use ASRock's RGB management software, and it controls the fans perfectly. Fully compatible, as promised.My only minor gripe is the Cooler Master ARGB connectors which are apparently proprietary. The plug style doesn't attach to the header very well. It's staying in place, but isn't all that secure. Also, in the daisy chain, connecting plugs requires an additional Cooler Master cap, which they include (so no worries), to hold the two ends of the plugs together. It makes those connections very secure, but they are a bit bulky which is mildly annoying when you're trying to find a place to tuck them.Anyway, quiet fans, gorgeous look. Pretty happy so far.

They're good fans. I have been using them for 3 years with no complaints. They look fantastic and are perfect for a clean and minimal build style. I didn't want to use any special software so I use OpenRGB and they work great. Not too noisy either.

Some keynotes for these fans:**Edit: mounting these fans face down and running above 70% rpm causes the fans to rattle. Any other mounting position is fine1) price: great value compared to other RGB loaded fans. You can get 6 for the price of 3 Corsair ll120 fans. And these fans are as good if not better than those.2) authenticity: these fans do in fact run anywhere from 1850-1975 RPM according to motherboard reporting.3) performance: these fans have more static pressure than other case fans which is better for getting air through case ventilation punchouts and dust filters. Have not tested on a radiator, however. I reccomend other fans for radiators anyways.4) installation: much much better than Corsair RGB fans but not the best as far as cables go. You can either hook up the RGB to your motherboard (3 pin rgb headers) or plug into the control box that comes with the 3 pack of fans. I use my motherboard. Works as expected.5) appearance: the RGB is very pretty. The reds are a little more dim than the rest of the lights but that's very normal and it's not distracting. Lights are bright but not blinding. Colors are pretty vivid. The blending of the light is also pretty good too. You have to really try to be able to distinguish where the individual LEDs are in the rings.6) asthetic versatility: these fans look good wherever you put them or angle you look at them. I have the lian li o11d XL and I have these fans on the bottom serving as intakes. This means you see the back of the fan instead of the front. Usually that means you can't see any of the RGBs and it looks ugly, but these fans have the rgb rings on the back as well and makes the fans MUCH more bearable to look at from the back of the fan. If you have a case with bottom fan mounts, I especially recommend these fans if you care about that noice PC asthetic.7) longevity: I expect these fans are not gonna have a great life expectancy given the price and MTF rating of 160k hours or whatever. Fortunately, these fans are cheaper and less bank breaking to replace.8) quality: despite my lower expectations for longevity, these fans look and feel very good quality.Overall, I'd highly reccomend these fans for anyone who doesn't want to spend Corsair money on fans. Despite what you might read in other reviews, I believe these fans to be very good for the money especially.

The media could not be loaded. I absolutely love these CoolerMaster Halo 120mm PC cooling fans, so much that I use them in almost every build I do. The fans have 24-LED's so every lighting sequence is nice and bright. These fans are perfectly diffused, so the lighting is nice and smooth with no hot spots. I highly recommend these fans, they're built well and have never failed on me.
