These fans work very well. I use them as case fans, and for AIO applications. They pump good airflow through my PC, and they provide enough pressure to be used on radiators. I chose simple white light LED. The white light is bright, and a very pure white light, it doesn't have the bluish tint that some other led fans have with their white light. The light cannot be turned off, which is something I don't mind. They are also on the noisy side, which is something that does not bother me as well.

Let me start by saying these fans are a great product. Very quiet, and the light diffusing out of the middle looks great, even if the fan is backwards. My one issue is that I have to pull of the stickers on the front. The sticker isn't perfectly centered so it looks terrible when the fan is spinning, bouncing around. I realize this is nitpicky, but most people who upgrade their computer are. Still 5 stars as a product.
