Product information: Storm Extreme Performance Universal WaterblockA few months ago, Swiftech acquired the manufacturing rights from well-known Australian engineer Stew Forster (AKA Cathar) for his extraordinarily efficient Storm G4 water-block. The resulting product combines our manufacturing know-how,attention to detail, and brings you the most advanced water-block ever produced by Swiftech: Storm, our new flagship. Storm has been designed by and for the die-hard enthusiast user. The body is high-precision machined out of Delrin™, a rugged Acetal resin chosen for its long term mechanical stability, and the base plate is made of C110 copper lapped to +/- 0.0003" flatness. Cosmetics have not been forgotten either, and the universal hold-down plate features a beautiful chrome finish contrasting with the black body. The cooling "engine" of the Storm is a pure jet impingement design. It uses 35 mini jets directing high velocity coolant into individually matching cups. In the designer's own words: "the Storm design implements jet disruptors to turbulate incoming jets prior to striking the cup's base". Swiftech fine-tuned the design to yield slightly better performance than the original in terms of thermal and flow resistance.
