If you plug it directly into a power supply course, it will function at 2000rpm, which gives you lots of air flow, but also loud noise. it's better to connect it to the motherboard(chassis fan plug) so you can adjust the speed.
the led effect is not as clear as the pic shown above.
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).
There isn't a groove for the screw itself, you have to make your own by forcing the screw in to the hole and repeatedly trying to screw it in. Skim through a few youtube videos and you'll see that this is a common issue.
