Corsair LL140 RGB 140mm Dual Light Loop RGB LED PWM Fan Single Pack Cooling

I have installed 5 of these fans in my current media/gaming pc build. I have the Corsair Graphite Series 760T full tower case with the NZXT Kraken 62 AOI cooler for my AMD Threadripper 1950x cpu.I replaced all 3 stock case fans with these Corsair LL series fans. I also replaced the 2 NZXT radiator fans with them. The fans not only look fantastic, but they are a lot quieter than the stock fans.The only complaint I have isn't really a complaint about the fans themselves. I have a full tower case loaded with hard drives, and when you want to add these fans to an already large system, it's just a rat's nest of cables and cable management is a hard task.The fans themselves are fantastic, and the program used for the lighting works in conjunction with my Corsair mouse, mouse pad and keyboard. I'm very happy with these fans! The pictures don't do them justice.

So, I bought 6 of these to redo all the fans in my 760T (there is an optional 120mm fan under the removable drive bay.) Out of all these fans, I really only ran into one problem. The ones that I mounted into my radiator, and front and bottom, all worked flawlessly. The one I mounted on the rear of the case, was a real pain. I had to manually thread the screws through the plastic (the screws that it CAME WITH). I wish I knew I was gonna do that ahead of time, but I pulled it out and screwed all 4 screws in and out a few times, and then I was able to mount it to the rear.As for cooling, I usually set all my stuff to performance mode, so they're not exactly quiet but if you set it in silent mode they are actually silent.. These are in charge of cooling an i7 7700K (with a Kraken X62 AIO,) and GTX 1080. My CPU temp is noticeably lower, probably about 7-10 degree's lower than when I used the stock fans that came with the Kraken. Both the GTX and the i7 7700K now are at idle temps of about 25 Celsius, where they used to idle around 30-35.The lighting is amazing, they are super bright and really light my case up well. One thing I can complain about, is in order to have these fans facing the correct way for the "Pong" lighting effect, is to have the side with the cable pointed towards the outside of the case. Because of this, if you want to use the Pong effect you will have to find a way to hide the wiring, or just don't use it. I can't really say it's too big of a deal because I don't personally use it, and Corsair gives you a bunch of different color effects to use.To have the ability to control the lights, I have a the fan hub that was provided with the triple pack I also purchased, to the Corsair Lighting Node Pro that I got with the lighting strips with Corsair. But due to how Corsair sells these, if you get any pack you have to pay extra to get the Lighting Node Pro, or you have to spend even more to buy the fans individually. No big deal, but I have 2 Corsair Lighting Node Pro's that I don't need and more than likely attempt to resell.I have seen a lot of reviews saying you need to buy an 80 controller to get the lighting effects, that is not true. You need to get a Lighting Node Pro, which connects to an on-board USB header, which is roughly 40-50, and have the fan hub connected to it.Yes, each fan has 2 cables connected to it, and I have 6 so essentially I have 12 cables. Could this have been better designed, yes. Is it necessary for my needs? No, because I have more than enough room around back to have them.Another complaint I have seen, is people cannot get the fans to light up, even with software. Now, I discovered this when I was installing my Corsair LED strips, you have to go into the Corsair Link software, find the lights, and press the + button and apply. Otherwise, you will only have 1 fan lighting up, it's frustrating at first if you didn't figure this out, but now you know.It is important to have the fans on the fan controller, plugged in IN ORDER for certain lighting effects. Also, DO NOT SKIP a port on the fan hub, or else every light after the connector you skipped, will not light up. For instance, don't have them in 1 2 4 5. (4 and 5 will not work.) Make sure they are 1 2 3 4 5, etc.Overall, I do believe these fans were worth the money to replace the stock fans that the case and Kraken X62 came with. Sorry this review is kind of scattered, just had surgery and on medication. But if you skimmed it and you are having problems with your fans, I highly suggest you read it for some tips, and feel free to respond if you have any other questions.

These fans are pricey. However they are dang near silent! I am impressed. The color is vibrant! And with iCue you can change the colors or completely turn them off. Whatever you want. I highly recommend these fans.

I love these fans. They not only have LED's around the inner circumference of the fan, but also in the center as well, so they really light up a case nicely. With the Corsair iCUE software, you can choose from preset effects or create your own. And all Corsair RGB products can be controlled to some degree in the software. In the pic I uploaded, I have 3 LL120 fans and 1 LL140, along with Corsair RGB Memory and recently I bought a Corsair Void Pro RGB Headset. If you are on the fence about how to hook these fans up, search Youtube for a video I made on how these are connected. Check the comments out for answers to a lot of common questions people have about these fans. If you are still not sure and have questions, ask me on YouTube or here on Amazon and I'll do my best to answer them. The name of the video is....Corsair LL120 3 Pack - Easy to see connections
