The ARCTIC Liquid Freezer III Pro 240 A-RGB is an all-in-one CPU water cooler for PC builders who want liquid cooling with addressable lighting. It suits gaming and performance systems using supported Intel or AMD processors, provided the case has room for its radiator.

Two P12 Pro A-RGB radiator fans run from 600 to 3000 rpm, while an integrated PWM-controlled VRM fan helps lower voltage regulator temperatures. Offset mounting moves the cold plate towards the CPU hotspot to support heat transfer. The 38 mm radiator is thicker than conventional 27 mm radiators and holds more liquid, helping it handle temperature spikes. Pre-installed, pre-wired fans and cable management integrated into the sleeving make installation tidier.

Key features

• All-in-one liquid CPU cooling with a 240 mm radiator.
• Two P12 Pro A-RGB fans with fluid dynamic bearings.
• Integrated PWM-controlled fan for cooling the motherboard voltage regulators.
• Offset mounting positions the cold plate over the CPU hotspot.
• Intel contact frame distributes contact pressure for supported Intel sockets.
• Fan cables run inside the sleeving to reduce cable clutter.
• Choose a single PWM connection for synchronised control or a splitter for separate pump, VRM fan and radiator fan control.
• Includes MX-6 thermal paste and has a 6-year warranty.

Compatibility

Supports Intel LGA1851 and LGA1700, and AMD AM5 and AM4 sockets. Check the case for at least 63 mm of installation clearance and confirm radiator fitment. Some motherboards may be incompatible because of oversized SSD coolers in the M.2_1 slot. A-RGB lighting uses a 3-pin 5 V connection. Good to know: Check motherboard and case compatibility before purchase, as motherboard heatsinks and limited clearance can prevent installation.
