Optimized Heat Dispatching: Thermaltake R Series Radiators deliver an average heating load of 32?-35?. After brazing, the fin and tube connect to form a joint, thereby creating uniform heat transfer. Slim Form Factor Design: R Series is a slim radiator with a 13-set flat tube design to increase heat transfer. Water flows down on one side, and then circulates back to the other side of the radiator. High-Density Fin Design: The cooling performance improves significantly with increased fan speed, offering exceptional cooling performance during operation. FPI (fin per inch): 17. German-Made Anti-Corrosion Materials: Designed with German aerospace-grade materials and constructed with zinc. Corrosion potentials of aluminum alloy with zinc can be reduced by 55.6% after brazing. Style:Pacific R120 The Thermaltake Pacific R120 introduces high-quality radiators to deliver outstanding water cooling performance for the enthusiast's PC. Manufactured from high-quality German aluminum alloy and aerospace-grade materials, configurations of 120mm to provide exceptional performance. Integrated G1/4" threads make it easy to install, while rigid connections ensure leak-resistant measures are in place.
