This article covers ARCTIC リキッドCPUクーラー240 静音即使用簡単設置.

Overview

ARCTIC's Liquid Freezer III 240 is an all-in-one liquid CPU cooler featuring a 240mm radiator designed for quiet and efficient cooling. It supports Intel LGA1700 and AMD AM4/AM5 sockets, making it compatible with a wide range of modern CPUs. The cooler comes with pre-installed push-configuration fans, so you can take it out of the box and mount it immediately without extra wiring effort. A patented LGA1700 contact frame prevents CPU deformation and improves thermal stability, while the included MX-6 thermal paste ensures optimal heat transfer. The high-static-pressure P-series fans and an optimized pump keep noise levels low even under heavy loads.

Compatibility Guide

Socket support includes Intel LGA1700 and AMD AM4/AM5. The LGA1700 contact frame attaches directly to the motherboard backplate, reducing physical stress on the CPU. Memory clearance is generally excellent since the radiator mounts away from the socket area, but you should verify that your case has adequate space for a 38mm thick radiator (standard 240mm mounts require approximately 55mm total depth including fans).

Product Info

The Liquid Freezer III 240 was launched in 2023 and is positioned as a mid-range AIO cooler with strong value. The typical street price is around ¥14,000–¥16,000 in Japan, and it comes with a 2-year warranty from the date of purchase. While exact TDP is not published, it can comfortably handle CPUs up to about 200W under sustained load. Market positioning places it between high-end air coolers and premium 360mm AIOs, offering a balanced mix of cooling performance, noise level, and price. Availability is good through major retailers and .

Best Use Cases

Mid-range gaming builds: Ideal for Core i5/Ryzen 5 up to Core i7/Ryzen 7 CPUs. The 240mm radiator fits most standard ATX cases, and the quiet operation won't distract during gameplay. Silent workstation setups: For content creators running long rendering or encoding sessions, the low noise pump and fans keep the environment distraction-free while maintaining safe CPU temperatures. First-time AIO buyers: Pre-installed fans and integrated cable management inside the tubing make installation nearly as simple as mounting an air cooler. The included MX-6 paste and clear manual lower the entry barrier.

Things to Consider

The radiator is 38mm thick, thicker than the typical 27mm. Some compact or slim cases may not have enough clearance – always double-check your case's radiator support specs before purchase. The built-in VRM fan provides auxiliary cooling for the motherboard's voltage regulators, which can help in cases with limited airflow but is not essential for CPU cooling alone. Compared to similarly priced 240mm AIOs, ARCTIC is known for quiet pump operation. However, like all liquid coolers, gradual coolant evaporation can reduce performance over time; the 2-year warranty covers defects within that period. Using the LGA1700 contact frame requires removing the socket cover, which may void the motherboard warranty. Proceed at your own risk.
