Review on upHere PF1206-5: 5-Pack 120mm Intelligent RGB Fans with Silent Control, Controller, and Remote by Scott Decoteau

I added all 5 to my computer. They work well, feel like decent quality, are fairly quiet and move a decent amount of air. Obviously, these aren't high-performance fans, but they do a pretty good job. Considering the price and how good they look I think this is a great deal. There are many different modes that you can set the fan LEDs to. I just keep them in this rainbow swirl mode. That looks great. You can set solid colors, different patterns, change the brightness or leave it on auto and it will cycle through the options on its own. Pretty cool stuff.
