ARCTIC Liquid Freezer III Pro 240 AIO CPU Cooler

This all-in-one liquid cooler uses a 240 mm radiator and integrated VRM fan to dissipate heat from high-end desktop processors. A copper cold plate with micro-skived fins transfers thermal energy into the coolant loop. The pump runs at 3000 rpm on a ceramic bearing for long-term durability. Only a single PWM cable connects to the motherboard thanks to integrated cable routing.

Intel LGA1700 and LGA1851 contact frame

A dedicated contact frame redistributes mounting pressure across Intel LGA1700 and LGA1851 sockets to protect the CPU substrate and improve heat transfer. Native offset mounting shifts the cold plate toward the processor hotspot on both Intel and AMD platforms. This mechanical change is the specification that decides whether the cooler matches your socket and workload.

Thermals, noise and power draw in normal use

Two P12 Pro fans push up to 77 CFM at 3000 rpm while the pump and fans are rated at 0 sones for near-silent operation. The 4-pin PWM connectors allow the motherboard to scale speed with load, reducing power draw when the CPU is idle. Aluminium radiator tubes and copper construction maintain consistent coolant temperatures during sustained workloads.

Questions sur cet article

How much airflow does the 240 mm radiator deliver once it is installed in a case?

The two P12 Pro fans on the 240 mm radiator each move up to 77 cubic feet per minute, so the cooler pushes that volume of air through the fin stack under load.

What does the 4-pin PWM fan connector control on this cooler?

The single 4-pin PWM header drives both radiator fans and the integrated VRM fan together, letting the motherboard regulate every fan speed from one signal.

Will the cold-plate block clear tall memory modules on an LGA1700 board?

The block measures 10.9 by 4.7 by 2.6 inches and uses a native offset mount that shifts the cold plate toward the CPU hotspot, leaving the top memory slots free on LGA1700 and LGA1851 platforms.
