Alpenföhn 120mm Wing Boost 2... thoughts?

I'm having trouble finding much in the way of reviews of these, although the original Wing Boost is certainly well regarded. Does anyone have any first hand experience? I'm thinking of using them as case fans in a Cooltek W2, x2 bottom intake and x1 rear exhaust. Would they be good choices, or are there better alternatives?

Thanks. They certainly LOOK solid and well made, and the progeny with the original Wing Boost bodes well for sure. Didn't seem likely that it would be worse! I was surprised that the original is actually more expensive though.

Very interesting. I never knew they were basically the same fan. I like the white look that the Parvum comes in also. Seems it's not the best performer however, but no slouch by any means.
