I have been looking for a couple of these for some time now. Every site I go to is out of stock in this one and most of the other versions. The only site that had an ETA was New Egg and that came and went with no stock. Is it just that these fans are that popular and sell out or is this fan going away? Any ideas? I wanted two of these to put on a Corsair H70 in a new build and it is the only thing I can't find.
