"The new Hydro series sealed-loop water coolers from Corsair that we got a sneak peek of earlier this month have now been officially announced by Corsair. The H80 is a double-thick 120mm radiator, and will be compatible with the majority of standard ATX cases on the market. In contrast, the H100 uses a dual 120mm radiator and will require modding or a case that supports mounting holes for standard 240mm radiators."
For the sake of comparison, the new ASETEK watercooler is pictured below.
