Features

The Hailstone is a liquid cooler series created to bridge the gap between enthusiasts and professional markets. The water block, pump, and radiator are from the powerful IceMyst Pro series while the included three fans are industrial FHL120 that SilverStone launched in late 2025. Combined, they offer excellent performance that will easily cool any enthusiasts-grade AMD Ryzen or Intel Core CPUs. Like the IceMyst Pro, the Hailstone also has full CPU coverage for the Ryzen Threadripper so you can utilize it for a serious workstation build as well. For additional cooling around the CPU area on components such as VRM, SSD, or RAM, the Hailstone allows for stacking installation of IMF70 rotatable add-on fans.

Large copper base for AMD Ryzen Threadripper Pro, covers CPU and supports mainstream AMD/Intel sockets.
3 x 120mm high-performance industrial fans featuring Liquid Crystal Polymer (LCP) blades.
Next-gen three-phase, six-pole motor delivers double the max flow (LPM)
Expandable water block supports IMF70 for enhanced cooling performance.
Rotatable pump cap aligns snowflake logo with any case.
