If you like ARGB then these are very nice. The cabling is easy because they can be daisy chained. I used two of the 140mm variety at the front of my case, three 120 mm on my Fractal Celsius S36 and a 120mm at the back of my case (Corsair 5000D Airflow). I had to use the included longer jumper cable between the 140mm fans at the front of the case, but I was able to chain the rest using the short cables. The rear case fan was the last in the chain so this had the fan cable that ran back to the controller. Overall, cabling was a breeze with these. I wired the controller to my ARGB header on my motherboard and let Armoury Crate control the lighting. Unlike the other reviewer, I had no issues with any of my cables, though I mounted them to the fan bracket of my case and radiator and tested them outside my case before fully cable managing, just in case.

Weakness is literally the weakness of these fans. The frame / ring around these fans is a very thin clear plastic, you have to be careful torqueing in the fan screws. The screws aren't easily screwed in and under that torque the frame twists and I think if you were over zealous, you could crack or break this ring. My suggestion is to maybe put the screws into the fan before mounting them in your case so that you can sufficiently support the frame while cutting the threads into the screw holes. Then back the screws out and mount them. This way you've precut the threads where you can keep the twist to the frame at a minimum.

Weaknesses (Cont) Another weakness in my opinion is the way the ARGB is chained, the LEDs aren't addressed continuously. There are 8 LEDs in each fan, so if you have 6 fans chained, instead of having 48 individual LEDs, you have 6 groups of 8 LEDs. Which means that there are 6 #1 LEDs, 6 #2 LEDs, and so on. So when LED #1 is turned on, all #1 LEDs are turned on. Not a big deal for simple patterns such as Breathing or Static, but more intricate patterns are matched across all fans simultaneously. This is subjective, some may not be turned off by this, I was a little disappointed though. So overall I'm very pleased with these fans. The 120mm fans have great static pressure and are ideal for pushing air through restrictions such as a dense heatsink or radiator. The ARGB is very nice if you like that sort or thing.

Cable management is really nice, can daisy chain fans with a single cable between fans ARGB looks nice.

Bought 2 boxes, had 2 dead cables. Luckily for my set up it was the two redundant cables because I chained all 6 fans together. The failed cables were: ARGB to controller (bad MB connector) and long extension cable you'd use to continue a run of fans. Luckily because I had 2 boxes and 2 redundant cables I could swap cables till things worked. But was a PITA, had to remove fans and nice wiring to troubleshoot. So my advice is, test all the connections and everything works as expected BEFORE integrating into your box. Other weaknesses: can still hear them on lowest RPM, screwing in mounting points causes the frame to flex, best to hold the frame while tightening screws.

Cable management would have been a big win except for 2 dead cables. Would be nice to have them totally silent at minimum RPM, maybe it's my MB that can't spin them slow enough.
