SilverStone showed off a new cooling portfolio at Computex 2026, emphasizing server, workstation and industrial use. The headline product, HailStone 420, is a 420 mm all‑in‑one built for Threadripper PRO rigs, featuring a 84 × 73 × 65 mm copper base and dual 140 mm fans that spin 800‑2500 RPM for up to 123.8 CFM airflow.

The XE420 expands the XE360 server AIO line into a larger 420 mm radiator (140 × 28 × 456 mm) with an integrated pump and industrial‑grade LCP blade fans, keeping the same 123.8 CFM and 800‑2500 RPM profile. New high‑airflow fans FHL120 and FHL140 deliver 95.1 CFM at 39.6 dB and 123.8 CFM at 38.8 dB respectively, both on dual ball bearings. Upgrade kits XAC‑F70‑C and IMF70‑BC add 70 mm fans for VRM, RAM and direct waterblock cooling.

Consumer‑focused models also appeared, including the Frost Knight S360 Elite with LCD display and white blades, an all‑black S360 Pro, and the Frost Mage 620 Pro CPU air cooler. By targeting both enterprise and DIY markets, SilverStone aims to capture a broader share of the high‑performance cooling segment as demand for dense, liquid‑cooled builds rises.

The showcase signals a shift toward larger 420 mm radiators, which deliver greater thermal headroom for multi‑GPU and AI workloads. Manufacturers that can pair high airflow with low acoustic output stand to win contracts in data centers and workstations, where silence and reliability are as critical as raw cooling power.
