ARCTIC LFIII Pro 360 Liquid Cooler Metal Radiator

Description

Product Overview

The ARCTIC LFIII Pro 360 is a premium all‑in‑one liquid cooling solution engineered for enthusiasts who demand consistent thermal performance without compromising on noise levels. Housed in a CNC‑machined aluminum and steel radiator, the unit measures 15.7 inches in length, 4.7 inches in width, and 2.9 inches in height, offering a compact footprint that fits most mid‑tower cases. The cooling loop circulates a 3.96‑watt, 12‑volt liquid through a copper cold plate that directly contacts the CPU, while the 3000 RPM P12 Pro fan pushes 77 CFM of air through the radiator fins. A dedicated PWM‑controlled VRM fan cools the motherboard’s voltage regulators, extending component lifespan. Constructed from a blend of metal, high‑grade plastic, and rubber sealing gaskets, the system is built to resist corrosion and leakage over years of operation. Compatibility spans a wide range of Intel LGA1851/LGA1700 and AMD sockets, making it a versatile choice for both new builds and upgrades.

Usage

Designed for high‑performance desktop rigs and modern gaming consoles, the LFIII Pro 360 excels in environments where sustained load and overclocking are common. Whether you are rendering 4K video, running intensive simulations, or pushing frame rates in the latest titles, the cooler maintains CPU temperatures well below throttling thresholds. Its low‑profile design also suits compact gaming PCs where space is at a premium. Installation is straightforward thanks to the native offset mounting system that aligns the cold plate with the CPU’s hotspot, reducing thermal resistance. The integrated cable management routes PWM fan cables through the radiator sleeves, leaving only a single clean connector to the motherboard, which simplifies cable routing and improves airflow inside the case.

Why Choose Us

ARCTIC’s reputation for rigorous testing and quality control underpins every LFIII Pro 360 unit. Each cooler undergoes a 24‑hour burn‑in test to verify leak‑free operation and consistent pump performance. The metal radiator not only offers superior heat dissipation compared to plastic alternatives but also resists deformation under high thermal stress. The P12 Pro fan delivers a unique blade geometry that provides higher static pressure at low speeds, ensuring quiet operation during idle while still achieving maximum airflow when needed. Integrated VRM cooling is a differentiator rarely found in competing AIO solutions, protecting the motherboard’s power delivery components and reducing overall system temperature. Backed by a 3‑year warranty, the LFIII Pro 360 gives confidence to builders who demand reliability and longevity.

FAQ

Is the LFIII Pro 360 compatible with my AMD Ryzen processor?

Yes. The cooler includes native offset mounting hardware for all current AMD sockets, positioning the cold plate directly over the CPU’s hotspot for optimal heat transfer.

Do I need to purchase additional brackets for Intel LGA1700?

No additional brackets are required. The package contains a dedicated contact frame designed specifically for Intel LGA1700 and LGA1851 sockets, providing ready‑to‑install mounting hardware.

How loud is the P12 Pro fan at low and high speeds?

At low speeds (around 800 RPM) the fan operates below 20 dBA, making it virtually silent during idle. At maximum speed (3000 RPM) it reaches approximately 35 dBA, still quieter than many stock air coolers under load.

Can I use the LFIII Pro 360 with a gaming console?

Absolutely. The cooler’s 4‑pin power connector and 12‑volt operation are compatible with the latest gaming consoles that support external liquid cooling solutions, providing improved thermal headroom for extended play sessions.

What is the warranty period for this cooler?

ARCTIC offers a three‑year limited warranty covering defects in materials and workmanship, giving you peace of mind for long‑term use.
