  • Contact frame on Intel LGA1851/1700 spreads pressure for longer CPU life and better heat transfer
  • Native offset mounting on AMD and Intel shifts cold plate toward the hotspot for more efficient heat transfer
  • Integrated VRM fan lowers voltage-converter temperatures for reliable performance under load
  • P14 Pro fans deliver up to 110 CFM at 2500 rpm while emitting only 0.08 sones
  • Cable management routes PWM wires inside the hose sheathing so only one cable reaches the motherboard

Ready for AM5, LGA1851 and LGA1700

The ARCTIC Liquid Freezer III Pro 280 is a 280 mm all-in-one liquid cooler built for AMD Socket AM5 and Intel LGA1851 or LGA1700 processors. It uses a copper cold plate with an integrated VRM fan and ships with two 140 mm P14 Pro fans mounted on a copper radiator. The pump runs at 2500 rpm and delivers 110 cubic feet per minute of flow.

Check socket, radiator space and header count

Verify that your motherboard uses AM5, LGA1851 or LGA1700 and that the case can fit a 280 mm radiator with two 140 mm fans. The block measures 12.4 by 5.4 by 1.5 inches, so confirm clearance around the CPU socket and memory slots. You will need one 4-pin PWM header for the pump and VRM fan plus one 4-pin header or splitter for the two radiator fans.

Pump noise 0.08 sones at 2500 rpm

In normal operation the pump and each fan spin at 2500 rpm while producing only 0.08 sones of noise. The integrated VRM fan is PWM-controlled and runs only when the voltage regulators need extra airflow. Tubing sleeves hide the fan cables so a single visible lead reaches the motherboard, keeping airflow paths clean and acoustic signature low.

Questions about this item

Does the box include the contact frame for Intel LGA1700 or do I need to buy it separately?

The contact frame for Intel LGA1700 and LGA1851 is included in the box so no separate purchase is required for those sockets.

Should I choose the 280 mm version over a smaller radiator for an overclocked CPU?

The 280 mm radiator with dual 140 mm fans provides the surface area and airflow needed for sustained loads on overclocked processors.

What does the 2500 rpm pump speed mean for actual coolant flow and noise?

The pump runs at 2500 rpm and is rated at 0.08 sones, delivering strong circulation while remaining very quiet in typical cases.
