ARCTIC Liquid Freezer III Pro 360mm AIO CPU Liquid Cooler
The ARCTIC Liquid Freezer III Pro 360mm AIO CPU Liquid Cooler is built for enthusiasts and power users who need reliable, high-capacity cooling for demanding workloads. It features a 38 mm thick radiator, native offset cold-plate mounting for Intel and AMD platforms, and an integrated PWM-controlled VRM fan that keeps voltage regulators stable under sustained load. An integrated cable management system routes PWM cables inside the tube sleeve, leaving only a single cable connecting to the motherboard.
Why this product
Thicker radiator holds more liquid
At 38 mm deep, the radiator holds more coolant than conventional 27 mm designs and provides greater surface area for heat dissipation.
Offset cold plate targets CPU hotspot
The cold plate center is shifted toward the CPU hotspot on both Intel and AMD platforms, improving heat transfer efficiency without adapters.
Integrated VRM fan for voltage regulator cooling
A dedicated PWM-controlled fan runs at 400–2500 rpm to actively lower voltage regulator temperatures, supporting stable performance under heavy loads.
P12 Pro fans: quieter at low speeds, stronger at high
The three included P12 Pro fans spin from 600 to 3000 rpm and deliver more airflow and less noise at low speeds compared to the standard P12.
Cable clutter reduced by integrated sleeving
Radiator fan PWM cables are routed inside the tube sleeve, so only a single cable is visible between the cooler and the motherboard.
Six-year warranty
ARCTIC backs this cooler with a 6-year warranty, reflecting confidence in the long-term reliability of the pump and components.

- SKUARC-3514
- EAN4895265000249
- Intel LGA1851 and LGA1700 sockets, with a contact frame optimized for pressure distribution on these platforms.
- AMD AM5 and AM4 sockets, with native offset mounting support on both.
- Some motherboards with oversized M.2 SSD coolers in the M.2_1 slot may be physically incompatible. ARCTIC provides a compatible M.2 cooler free of charge for affected boards.
- Tubes measure 450 mm in length — verify case clearance and radiator mounting space before installing.
- The pump requires 12 V DC at up to 0.35 A; confirm your motherboard or fan hub can supply this.
Best for
- High-load desktop builds where sustained CPU performance requires both processor and VRM cooling simultaneously.
- Intel LGA1851 / LGA1700 and AMD AM5 / AM4 builds that benefit from the contact-frame optimized pressure distribution and offset cold plate.
- Builders who value tidy cable runs, since the integrated sleeve routing eliminates most radiator fan cables from view.
- Long-term ownership backed by a 6-year warranty and included MX-6 thermal paste.
- Cases with 360 mm radiator support and room for a 398 × 120 × 38 mm unit plus 450 mm tube routing.
Trade-offs
- Small-form-factor or compact cases that cannot accommodate a 360 mm radiator measuring 398 × 120 × 38 mm.
- Builders with oversized M.2 coolers in the M.2_1 slot who are not prepared for the possibility of a physical conflict near the socket area.
- Platforms other than Intel LGA1851/LGA1700 or AMD AM5/AM4 — no other socket compatibility is stated for this cooler.
- Weight-sensitive or transport-heavy setups — the total cooler weight is 2020 g, which adds meaningful mass to the system.
PWM-controlled fan lowers the voltage regulator temperature, ensuring stable performance.
Shifts the cold plate to the CPU hotspot for more efficient heat transfer.
Optimized contact pressure distribution for longer CPU lifespan and improved heat dissipation.
Fan cables integrated into the sleeving simplify installation and minimize cable clutter.
The P12 Pro unleashes its full potential: quieter and more powerful at low speeds, with greater performance reserves under load—for maximum cooling without compromise.
The 38 mm radiator not only enhances heat dissipation but also holds more liquid than conventional 27 mm radiators.
Some motherboards may be incompatible with the Liquid Freezer III Pro due to oversized SSD coolers in the M.2_1 slot. For affected motherboards, we provide a compatible M.2 cooler free of charge.
