Silverstone Shows Off Its Cooling Solutions at Computex 2026

SilverStone’s Computex 2026 cooling showcase leaned heavily into server, workstation and industrial applications. The HailStone 420 is a 420 mm AIO targeting workstation platforms including AMD Threadripper PRO. With an 84 x 73 x 65 mm copper base waterblock and 140 mm fans spinning between 800 and 2500 RPM it reaches up to 123.8 CFM. The XE420 extends the well-received XE360 server AIO lineup to a larger 420 mm format (140 x 28 x 456 mm), built for server and industrial environments with a radiator-integrated pump, industrial 140 mm LCP blade fans, and a vibration-reducing design. The fan speed and airflow specs are the same as the HailStone 420.

The FHL120 and FHL140 are high-airflow fans. The 140 mm version runs at 800 to 2500 RPM at 123.8 CFM and 38.8 dB(A), while the 120 mm reaches 95.1 CFM at 39.6 dB(A). Both run on dual ball bearings while measuring 27 mm (FHL120) and 34 mm (FHL140) thick.

The XAC-F70-C is a 70 mm fan upgrade kit for XE360 and XE420 series coolers, designed to improve VRM and RAM cooling on liquid-cooled systems, running 600-4200 RPM at 25.8 CFM in a 118 x 29 x 92 mm package. The IMF70-BC is a companion 70 mm fan intended for direct mounting on IceMyst and HailStone AIO waterblocks, same speed and airflow spec in a 73 x 16 x 143 mm form factor with dual ball bearings. Also on display were the consumer oriented series like Frost Knight S360 Elite LCD W AIO featuring white fan blades, an all-black Frost Knight S360 Pro AIO and Frost Mage 620 Pro CPU air coolers.
