All-in-one liquid cooler

The ASUS PROART LC 420 is a closed-loop CPU cooler that combines a copper cold plate with a 456 x 140 x 30 mm aluminium radiator. Three Noctua NF-A14 industrialPPC-2000 PWM 140 mm fans push up to 107 CFM at 31.5 dB(A). A built-in illuminated meter displays live load, temperature and fan speed data.

Workstation builders needing broad socket support

The block fits AMD AM4, AM5 and Intel LGA 1150, 1151, 1155, 1156, 1200, 1700 and 1851 sockets, covering current and many recent platforms. Builders who require a smaller radiator for compact chassis or who prefer air cooling should look at other solutions.

450 mm sleeved tubing length

The reinforced rubber tubes measure 450 mm end to end, setting the maximum distance between the CPU block and the radiator mounting points. Verify that your case layout can accommodate this reach before purchasing.

商品問答

What case clearance is needed for the 456 mm long radiator with three 140 mm fans?

The radiator measures 456 x 140 x 30 mm and requires three 140 mm fan slots; verify your chassis supports a 420 mm class radiator with 30 mm thickness plus fan depth.

Which mounting bracket and screw set do I use for an Intel LGA 1700 or AMD AM5 socket?

The accessory pack includes dedicated brackets for Intel LGA 1700/1851 and AMD AM5/AM4; select the correct bracket, apply the pre-applied thermal compound, and torque the captive screws evenly in a cross pattern.

How often should the pre-applied thermal compound be replaced and can the sleeved rubber tubes be serviced?

Replace the thermal compound every two to three years when reseating the block; the 450 mm sleeved rubber tubes are sealed and not user-serviceable, so the unit is replaced if coolant loss occurs.
