Corsair might not have been the first to bring the all-in-one water cooler to the market, but the Hydro series was the force behind making them a household name. It all started with the Asetek designed H50, which was by no means a perfect product, but its simplicity, performance and acoustics made it a commercial success. Since then Corsair has switched their Hydro series over from the Asetek design to one from CoolIt. Their latest coolers, however, the H110 and H90 are once again created by Asetek, but they are based on their latest 4th generation design.
