ARCTIC Liquid Freezer III Pro 280 AIO CPU Cooler 280mm
The ARCTIC Liquid Freezer III Pro 280 AIO CPU Cooler is a 280mm all-in-one water cooler designed for Intel and AMD processors. It combines PWM-controlled fans with a repositioned cold plate to target CPU hotspots, delivering quieter operation at low speeds and sustained performance under full load.
Why this product
Cold plate targets CPU hotspot
Shifts the contact point to where your CPU runs hottest, improving heat transfer efficiency compared to standard coolers.
PWM fan voltage control
Lowers voltage regulator temperature for stable performance and reduced noise at partial load.
Integrated fan cables
Cables run through the sleeving to simplify installation and reduce cable clutter inside your case.
Wide socket compatibility
Supports Intel LGA 1700 and 1851, plus AMD AM4 and AM5, covering most current platforms.
6-year warranty
ARCTIC backs the cooler with six years of coverage.

- Intel LGA 1700 and 1851 sockets
- AMD AM4 and AM5 sockets
- Requires at least 63 mm of vertical clearance inside your case for the pump block and radiator assembly
- Some motherboards with oversized M.2 SSD coolers may interfere; ARCTIC provides a compatible replacement M.2 cooler free of charge for affected boards
Best for
- Mid-range to high-end air-cooled CPU replacements
- Builds that prioritize low noise at idle and moderate loads
- Clean case aesthetics
- Systems with tight budget for CPU cooling and long-term reliability
Trade-offs
- Cases under 280mm width — the radiator is fixed at 317 mm long
- Extremely compact cases — 63 mm vertical clearance is a hard minimum and excludes many SFF builds
- Ambient temperatures above 40°C — operating range tops out at 40 °C
Multi Compatible All-in-One CPU Water Cooler
The P14 Pro unleashes its full potential: quieter and more powerful at low speeds, with greater performance reserves under load—for maximum cooling without compromise.
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.
Please note that the Liquid Freezer requires at least 63 mm of clearance for installation.
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.
