Summary: If my memory serves me correctly, I was on a tight budget so these were the cheapest fans available at the time. it works fine. Be warned: the screw heads strip off easily especially when there is no screw grooves on the plastic fan holes (you have to force screw and make your own).
Summary: I received this fan today and was anxious to see how quiet it runs and the amount of airflow it puts out. It's not a bad fan for the price and the LED's are nice and not too bright. I did notice that the fan is best if used as an exhaust fan mounted horizontally. It makes a bit of a ticking noise if mounted in any other position, I tried it in every position.
Summary: It seems that the side when you have the LED lights facing the inside of your computer is when the side with the least amount of airflow and when you have the LED lights facing outside of your computer is when you have the most airflow inside of your computer.
Summary: Lights don't radiate, just kind of shine. Wires are short and ugly. These are cheaply made and I would not buy them again. I bought 4 of these and uninstalled them after turning on the system. I didn't take the time to check air flow or noise.
Summary: I don't know if all fans eventually do this, but this thing always starts making noise after about a month of use. I can switch it from a vertical to a horizontal position, which stops the noise, but temporarily. All of the fans I bought did this. The fan works _very_ well (besides the noise), and I still have them in my desktop, but I don't plan on using the CM brand in the future.
Summary: They looks nice, they come with the 4pin converter for people who need it. They are nice and fast and push a lot of air but they are no where near silent as advertised. This computer is in a large finished basement and I can hear this one fan across the basement and up the staircase.
Does what it says it would, but nowhere near as well as it should

Summary: I bought this fan hoping to add some cool lighting to my rig, and when I saw the 19db rating I was friggin' amazed. Ends up, this thing is way, WAY louder than that. A plus, is that the LED's are really bright.
Summary: The fan provides a lot of air flow, which is good, but it is not very quiet. Perhaps I have received a faulty fan, judging by how most people consider it to be silent. It is significantly louder than the rest of my computer, to the point of where I can hear it through headphones. Also, the screws are difficult to get in.
