be quiet!Light Wings 140mm PWM, 3-Pack ARGB Cooling Fans, 14cm, Desktop Compatible

These fans perform well. They can be pushed to a ridiculous speed and they move a lot of air. I only bought them to use as exhaust because the info I had seen online seemed to show not a great deal of lighting bling when they were placed ugly side up (intake).They actually look pretty cool like this though as you can see from the second pic I've taken through the top of my case.These fans make a weird vibrating noise when spinning back down quickly from a high rpm but I suspect this is because I may have screwed them in too tightly. I will know for sure next time I move things around but when gradually reducing rpm there is no noise at all.You can't hear these fans up to around 1000rpm although every case is different so your mileage may vary.One thing I couldn't get an answer to before purchasing was whether the daisy chain connection (for RGB) linked the fans in series or parallel. They do include an active splitter in the box (which is useful to have) but when you link 3 fans to each other in a row without this splitter, your RGB controller will still only see the number of LEDs in one fan so the signal is being split in parallel. The use of the term 'daisy chain' is not accurate therefore - each fan simply contains its own passive signal splitter.This of course rules out funky visor-type effects across a whole bank of fans that is possible with some Corsair fans for example, but these perform significantly better in terms of cooling and noise than the QL120s they replaced.All in all I'm satisfied and would recommend.

All good, nice colours, easy to install, can change the colours from the fusion app with gigabyte/aorus motherboard. I have the issue with one cooler flashing, the fix was to unplug from the controller and plug in serial with another cooler.

Well made and very quiet even at the higher rpm. The fan hub is easy to hide and connects easily to the RGB header from the motherboard. Not the cheapest fans but for me worth the money.

Good fans but bit overpriced (£28-ish).

A little expensive but the multipack pricing works in their favour. But if you need any other number than 3 you should probably pick an alternative.
