Arctic has introduced maintenance-free liquid cooling systems Liquid Freezer III Pro. The Pro versions differ from the regular Liquid Freezer III models released last year by more efficient fans. At the moment, the company has only introduced the Liquid Freezer III Pro 360 model with a 360 mm radiator. During the second quarter of this year, the manufacturer will release versions with 240, 280 and 420 mm radiators.

For comparison: the Liquid Freezer III 360mm non-LED liquid cooling system uses 120mm P12 PWM fans with a speed of 200 to 1800 rpm, while the ARGB versions are equipped with P12 PWM PST A-RGB fans with a speed of 200 to 2000 rpm. The new Liquid Freezer III Pro 360 model received 120mm P12 Pro fans with a speed range of 600 to 3000 rpm. They create an air flow of 77 CFM and a static pressure of 6.9 mm H2O. Otherwise, both versions of the liquid cooling systems are identical. The cooling system pumps operate at speeds from 800 to 2000 rpm, and the compact fan installed on the water block rotates at a speed of 400 to 2500 rpm.
Replacing the fans with more efficient ones allowed to increase the cooling efficiency of the Liquid Freezer III Pro 360 relative to the regular Liquid Freezer III of the same size by several degrees. For example, the temperature of the AMD Ryzen 9 7950X chip with a power consumption of about 210 W and full speed of the liquid cooling system fans decreased from 88 to 84.2 °C. And with normalized fan speed and a noise level of 28 dBA – from 88.2 to 86.6 °C.
The Liquid Freezer III Pro 360 also copes with cooling the Intel Core Ultra 9 285K more effectively. Data from Arctic’s internal tests show that with a chip power consumption of about 250 W and maximum fan speed, the processor temperature in the Prime95 stress test was 69.3 °C instead of 79.9 °C for the regular Liquid Freezer III of the same size. And with normalized speed and a noise level of 28 dBA, the temperature was 72.2 °C for the Pro version versus 82.3 °C for the regular one.
The Liquid Freezer III Pro 360 will be available in both non-ARGB and ARGB versions. The Liquid Freezer III Pro 360 is priced at $124.99. The Liquid Freezer III Pro 360 A-RGB version is priced at $144.99, while the white Liquid Freezer III Pro 360 A-RGB version is priced at $149.99.
