I have used them as an exhaust fan and bottom supply fan in my new build. They work great, quiet, great airflow. They can also be used as fans to force air over the CPU cooler as they are static pressure fans that concentrate the air with more force in a smaller area. The lighting is great, you can set it to a single color or react to your desktop or games, and there are lots of random effects. The only thing I didn't like is that you have to manage a lot of cables so it takes a while to organize the back of the case, but in the end you can manage everything with a motherboard program like the Asus Aura, the is easy to use. Alternatively, you could use the included hardware controller, but that would mean opening up the case to change color or dangling it from the back of the computer, which would be messy. I am very happy with these fans.
