Conclusion:
GELID certainly has made an impressive entry into the fan market with what I have seen here today. Looking at both ends of the spectrum; silence and performance, both lines from them have great design and performance. I was very pleased at how silent the "Silent" series was and the Wing series also left me in surprise by being quieter than I would have expected for a higher performing fan. The only thing missing? More North American distributors! That will come with time though, keep in mind Gelid is still a fairly new company!

Pros:
'Silent' series actually is impressively silent in tests
Wing series introduces a great new bearing design to help keep high performance fans quieter
All fans have great noise and airflow specs, they aren't louder than they should be nor do they lack in airflow compared to competitors

Cons:
I wouldn't mind seeing 4 screws included too, this will let the fans be installed in areas where the rubber mounts simply won't work
Limited availability in North America still, especially Canada
