ASRock released its WS Series AIO liquid coolers with a redundant dual-pump design and support for thermal loads exceeding 500W, targeting Threadripper and Xeon workstation platforms that run under sustained load.
The lineup includes two models. The WS TR 360D supports AMD Threadripper sockets including sTR5, SP6, sWRX9, sWRX8, sTRX4, TR4, and SP3. The WS XE 360D is built for Intel Xeon W platforms using LGA4677 and LGA4710, matching workstation-class configurations detailed in Lenovo ThinkStation P5 Gen 2. Both models are designed for high-end desktop and workstation environments where uptime is critical.
Cooling hardware centers on a 360 mm radiator with a 38 mm thickness and a seamless one-piece brazed copper cold plate, similar large-format cooling approaches used in Thermalright AI Hydronous R1. The design spreads heat evenly across large CPU heat spreaders while maintaining consistent thermal transfer during long workloads.
A key feature is the dual-pump architecture running at around 4,000 RPM (±10%), a design approach aimed at sustained reliability in systems like Corsair AI Workstation 300. The design includes redundancy, allowing one pump to continue operating if the other fails. A built-in buzzer alert notifies users of pump failure, adding a layer of protection for continuous workloads such as rendering and simulation.
The cooler comes three 120 mm fans made from aerospace-grade LCP material, aligning with high-performance cooling components used in Antec 900 full tower case. These fans feature industrial dual-ball bearings and an IP54 rating for dust and water resistance. They operate between 0 and 3,000 RPM, delivering up to 89.7 CFM airflow and 4.7 mmH₂O static pressure, with noise levels reaching up to 39.7 dBA. A 0 RPM mode allows silent operation under low load.
The radiator measures approximately 400 × 120 × 38 mm, while tubing length is 450 mm using IIR and EPDM materials for durability. The water block dimensions differ slightly between models, with the Threadripper version measuring 78.9 × 119.3 × 25.2 mm and the Xeon version at 78 × 118 × 25.2 mm.
Compared to typical consumer AIO coolers, the WS Series is designed for sustained high-load conditions rather than short boost workloads, matching requirements outlined in laptops for deep learning. The combination of thicker radiator construction, high static pressure fans, and redundant pumps aligns with workstation and server requirements.
ASRock backs both models with a 6-year warranty, reinforcing long-term reliability expectations for professional use.
Sales begin on May 1 in Japan. The WS TR 360D and WS XE 360D are priced at 69,800 yen (around $438).
