The ARCTIC Liquid Freezer III Pro 240 is an all-in-one liquid CPU cooler for PC builders and enthusiasts using a compatible Intel or AMD system. Its 240 mm radiator and two P12 Pro fans suit gaming PCs and other builds that need active processor cooling.

The cooler combines a 38 mm aluminium radiator with a copper cold plate and PWM controlled pump. An integrated VRM fan also directs airflow towards the motherboard’s voltage regulators. The radiator fans are pre-installed, and their cables are integrated into the hose sleeving to help simplify installation and reduce cable clutter. The offset mounting shifts the cold plate towards the CPU hotspot for more efficient heat transfer.

Key features

• Two P12 Pro radiator fans run at 600–3000 rpm.
• The integrated VRM fan is PWM controlled and runs at 400–2500 rpm.
• The pump runs at 800–2800 rpm under PWM control.
• The 38 mm radiator holds more liquid than a conventional 27 mm radiator, helping it manage temperature spikes.
• Reinforced EPDM tubing has braided sheathing and measures 450 mm long.
• Separate or synchronised control of the pump, VRM fan and radiator fans is supported through the supplied PWM cable options.
• MX-6 thermal compound is included, and the product has a six-year manufacturer warranty.

Compatibility

Supports Intel LGA1851 and LGA1700, and AMD AM5 and AM4 sockets. Check that the case has at least 63 mm of clearance for installation. Some motherboards may also have a fit issue if an oversized SSD cooler occupies the M.2_1 slot. Good to know: check your case clearance and motherboard layout before buying; the CPU and case are not included.
