This article covers ARCTIC リキッドクーラー III 360 A-RGB CPU用.

Overview

The ARCTIC Liquid Freezer III 360 A-RGB is a high-performance all-in-one CPU liquid cooler from the German PC cooling specialist ARCTIC. Featuring a 360mm radiator and three 120mm A-RGB fans with PWM speed control up to 2000 RPM, it delivers excellent thermal performance for modern high-end CPUs. The pump unit incorporates an active VRM cooling fan that helps keep the voltage regulator modules cool under load. The cooler supports Intel LGA1851, LGA1700 (and LGA1200 via included bracket) and AMD AM5/AM4 sockets. It comes with an Intel contact frame that improves mounting pressure distribution and an AMD offset mount that shifts the cold plate 5mm to better cover the hotspots on Ryzen chiplet-based processors. A key design highlight is the integrated cable management: the fan PWM cables run inside the tubing sleeve, leaving only a single visible cable to the motherboard for a clean build.

Connectivity & Compatibility

The cooler is compatible with Intel LGA1851, LGA1700, LGA1200, and AMD AM5/AM4 sockets. Both the pump and fans connect via standard 4-pin PWM headers. The A-RGB lighting uses a 3-pin 5V addressable RGB connector and can be synchronized with major motherboard RGB ecosystems such as ASUS Aura Sync, MSI Mystic Light, and Gigabyte RGB Fusion. The radiator dimensions are 398 x 120 x 63 mm (including fans). Ensure your case supports a 360mm radiator in the top or front, with sufficient clearance for the 63mm thickness. Note that on some motherboards, an oversized M.2_1 heatsink may cause interference with the pump unit. In such cases, using M.2_2 slot or swapping to a low-profile heatsink can resolve the issue. ARCTIC provides an online compatibility checker on their website for pre-purchase verification.

Product Info

Launched in late 2023, the Liquid Freezer III 360 A-RGB is priced competitively at around ¥18,000–20,000 (US $120–$140 equivalent). It belongs to the mid-high tier of AIO liquid coolers, offering performance comparable to premium models from NZXT, Corsair, or Cooler Master while adding unique value through its integrated cable management and active VRM cooling. The warranty is a standard 2 years (extendable upon product registration). The package includes mounting kits for Intel and AMD, an Intel contact frame, a tube of ARCTIC MX-6 thermal paste, fan screws, and necessary RGB cables. The fans support daisy-chaining for simplified wiring. It is widely available at major PC component retailers including , Micro Center (US), and Japanese stores like Yodobashi Camera and Tsukumo.

Best Use Cases

This cooler is an excellent choice for gamers and content creators using high-end CPUs such as Intel Core i9 or AMD Ryzen 9, especially when overclocking or running all-core workloads. Its 360mm radiator provides ample cooling capacity to prevent thermal throttling during prolonged rendering, video encoding, or scientific simulations. The integrated cable management and single visible cable appeal to enthusiasts who value a clean, minimalist interior. The A-RGB lighting allows for personalized aesthetics that can be synced with other components. However, for users with lower-power CPUs (Core i5, Ryzen 5) or those who prioritize extreme quietness, a premium air cooler may be more cost-effective. Also, if your case cannot accommodate a 360mm radiator, consider the 280mm or 240mm versions of the same series for better compatibility.
