Get. These. Fans. Any versions, ASAP. RGB lover's dream.

I freakin love these fans. Premium, worth every penny. They feel sturdy in hand and look amazing. You can put anything you want on the LCD's and orient them as you please and they look bright and vibrant. Make sure you use the provided sata cable for power, using your own just wont work for some reason. Mine flickered and would reset every few seconds until i switched it. Otherwise 10/10 fans, glad i took a chance on these.

Clean and smiple.

At first I was like why do I need a fan with an LCD? Now I want more lol. The wireless function of these fans is really good. The software is easy to use and the ability to put custom videos and pictures is great. I love the look of the fans and wish I had switched sooner. Just having one cable instead of multiple is a game changer. Linking the fans together was easy too and fast. No more 10 plus fan cables to plug in for me lol. The LCD and colors are bright and beautiful. These fans do a nice job being quiet and keeping my case cool. Overall they feel well made and the reverse blade design makes for a beautiful looking case.
