Purpose-built cooling

The MSI MAG Coreliquid A12 240 is an all-in-one liquid cooler designed for mainstream desktop processors. It targets builders who want a closed-loop solution with integrated ARGB lighting and broad socket support. The unit fits LGA 1700, LGA 1851, AM5 and AM4 platforms without extra brackets. It suits users who prefer a pre-filled loop over custom plumbing.

Build and daily use

The 277 mm aluminum radiator mounts in standard 240 mm fan locations using two included 120 mm fans. Double ball bearings and 4-pin PWM connectors give each fan a 2200 RPM ceiling and 94.65 CFM maximum airflow. The pump block rotates so the logo stays level regardless of orientation. Evaporation-proof tubing resists coolant loss and bends easily during assembly. Mystic Light software controls the ARGB LEDs.

Interface limits

The pump runs at 3100 RPM with an average noise level of 15 dBA. Fan noise reaches 37.6 dB-A at full speed, so silent operation requires a lower PWM curve. The 4-pin PWM header is the only control link; there is no separate pump header or USB monitoring. Cooling capacity scales with radiator surface area and airflow, so heavy overclocks may exceed what this 240 mm loop can dissipate.

Questions about this item

What socket does the 240 mm AIO support out of the box?

The cooler includes mounting hardware for Intel LGA 1700 and LGA 1851 as well as AMD AM5 and AM4 sockets.

How much case clearance does the 277 mm radiator need?

The radiator measures 277 mm in length, so the case must provide at least that much space for a 240 mm dual-fan mount.

Which fan header do the two 120 mm ARGB PWM fans plug into?

Each fan uses a standard 4-pin PWM connector; connect them to the CPU_FAN and CPU_OPT headers or a PWM fan hub for speed control.
