This article covers ARCTIC Liquid Freezer WS360-SP6 ワークステーション向けオールインワン（AIO）CPU水冷クーラー.

Overview

The ARCTIC Liquid Freezer WS360-SP6 is an all-in-one liquid CPU cooler specifically designed for AMD's workstation sockets SP6 and sTR5. Unlike standard consumer AIOs, this unit features an enlarged cold plate and a dedicated mounting mechanism to properly cool the large CPU packages found on Threadripper PRO and EPYC platforms. Equipped with a 360mm radiator and three P12 Pro CO fans, the cooler delivers high static pressure for efficient heat dissipation. The fans use dual ball bearings, ensuring long-term reliability in 24/7 workstation environments. Noise levels are rated at just 0.08 sone, making it a quiet solution for demanding workloads.

Connectivity & Compatibility

This cooler is exclusively compatible with AMD SP6 and sTR5 sockets. It will not fit Intel LGA sockets or standard AMD AM5/AM4 motherboards due to the specialized cold plate size and mounting hardware. Power is supplied via a standard 3-pin or 4-pin PWM fan header, allowing motherboard-based speed control. The fixed-mount design requires the included backplate and brackets for installation; all necessary hardware is provided in the box.

Product Info

The ARCTIC Liquid Freezer WS360-SP6 launched in late 2025 as a high-end workstation cooling solution. It targets systems built around AMD Threadripper PRO (sTR5) and EPYC (SP6) processors, where standard AIOs often struggle with thermal management. ARCTIC backs this cooler with a 6-year warranty. The package includes three P12 Pro CO fans, a mounting kit, and pre-applied thermal paste. At around ¥33,960 (approx. $230 USD) on Japan, it offers competitive pricing for a workstation-grade 360mm AIO.

Best Use Cases

AMD Threadripper PRO / EPYC Builders: If you own a workstation motherboard with an SP6 or sTR5 socket, this cooler is one of the few AIO options that properly covers the large IHS. It handles sustained all-core loads from rendering, compiling, or simulation workloads without throttling. Creative Professionals Running Long Render Jobs: Video editors, 3D artists, and engineers who run CPU-intensive tasks for hours will benefit from the high thermal capacity of the 360mm radiator and the durability of dual-ball-bearing fans. * Noise-Sensitive Workstation Users: Despite its cooling capability, the P12 Pro CO fans operate quietly at 0.08 sone. This makes the WS360-SP6 suitable for shared office spaces or home studios where fan noise is a concern.

Things to Consider

Socket compatibility is the most critical factor — this cooler only works with AMD SP6 and sTR5. Double-check your motherboard's socket before purchasing. The 360mm radiator requires a case with sufficient clearance. The radiator itself is about 38mm thick, and adding 25mm fans brings the total to roughly 63mm. Measure your case's radiator mounting area and ensure there's enough room for the tubing as well. Priced higher than typical consumer AIOs, the WS360-SP6 is a specialized product. For standard gaming PCs, ARCTIC's Liquid Freezer III series offers better value. Only invest in this model if you genuinely need workstation-grade cooling. ## FAQ
Q: Can I use this cooler with an Intel CPU? A: No. This model is designed exclusively for AMD SP6 and sTR5 sockets. It is not compatible with Intel LGA1700, LGA1200, or any other Intel platform. Q: How thick is the radiator? A: The radiator is approximately 38mm thick. With fans attached, the total thickness is about 63mm. Ensure your case has enough clearance before installation. Q: Are the included fans replaceable? A: Yes, the fans use standard 120mm mounting holes, so you can swap them for other 120mm fans. However, the fixed-mount design means you should verify screw hole alignment and fan thickness to avoid clearance issues.
