The 80x25mm version is due to be released later this month and YS Tech told me they have no plans on releasing anything bigger than a 80mm version. So as of now no luck for the 92mm or the 120mm. There main market with this fan is the heatsink market. And since the mass majority of heatsinks use 70 and 80mm fans that is what they are concintrating on.
Btw, when the 80mm is released I will be getting it to replace my 70mm. I like the 70mm, but I dont think it covers a large enough surface area. YS tech will not release the specs of this fan until it is released, but I can tell you this. For one is 10mm larger and for two its 10mm wider. So I would guess somewhere around 45-50CFM rating on this fan, probally at about 35dbs, but that is just a guess.
