Nice looking fan, runs quietly. I have a mix of fans in my pc so I'm not certain how quiet but I'm considering changing out my other fans for this model. As an electrician I find the "flux field friction reduction" an interesting concept and hope to notice a difference. It claims to be dust and water resistant as well.
Weaknesses:
It claims to be "black light or UV reactive", I don't think I've seen anyone do it and I don't know how it would look. A bit tron-ish maybe? Also, I used the common mounting screws to install it 'cause I don't like little black nibs sticking out of my case in 2 dozen places.
Summary:
A good product at a good price. What more could you ask for?
