Overview

The MSI MAG CORELIQUID M240 is an all-in-one liquid CPU cooler built around a 240mm radiator, sold under the part number 306-7ZW4R14-813. It sits in MSI's MAG family, which positions it as a mid-range cooling option rather than a flagship. For anyone moving up from a tower air cooler, it is an approachable first step into liquid cooling.
The kit ships with two 120mm ARGB PWM fans, so lighting and airflow arrive together without buying extra fans. The tubing runs 400mm and uses a three-layer net plastic construction hidden beneath a reinforced mesh sleeve, a design intended to keep the coolant sealed inside the closed loop and limit evaporation over time.
Socket support spans both Intel and AMD, and LGA 1700 works straight out of the box. That makes the M240 relevant for a new gaming build as well as for rebuilding an existing air-cooled system where you want a cleaner internal layout. It targets buyers who want 240mm-class liquid cooling without paying flagship prices.

Compatibility Guide

On the AMD side the mounting bracket fits AM5, AM4 and TR4. Intel coverage includes LGA 1150, 1151, 1155, 1156, 1200, 1700, 2011, 2011-3 and 2066, which stretches from current mainstream boards up to large workstation sockets. LGA 1700 is explicitly listed as supported without extra parts.
Because the radiator is a 240mm unit, your case needs room for two 120mm fans side by side. Many mid-tower chassis accommodate this at the top or front, but check the fan mounting positions and radiator thickness clearance before you start disassembling anything.
The fans are PWM controlled, and a PWM cable for one to two fans is included. You connect them to a CPU_FAN or SYS_FAN header on the motherboard and let the board manage fan speed. Thermal paste is bundled as well, so you can complete the install without sourcing compound separately.

Product Info

The MAG CORELIQUID M240 launched on January 1, 2023 and occupies the entry-to-mid tier of the 240mm AIO market. Its package combines two 120mm ARGB PWM fans, 400mm of tubing, a bracket set covering both Intel and AMD sockets, and bundled thermal paste. Rather than chasing maximum cooling headroom, it leans on broad socket compatibility and straightforward assembly, which is the right trade-off for this price bracket.

Best Use Cases

  • First-time liquid cooling builders: LGA 1700 and the other major sockets work out of the box and paste is included, so fewer extra parts are needed. Skip it if your case cannot host a 240mm radiator.
  • Builders who want ARGB inside the chassis: two 120mm ARGB PWM fans come in the box, so a lit liquid-cooling setup needs no additional fans. A silent, lighting-free build would be over-served here.
  • Anyone fighting air-cooler clearance: moving from a tall heatsink to a 240mm radiator frees up space around the memory slots. In a case with no viable radiator mount, that benefit disappears.

Things to Consider

A 240mm radiator has less surface area than a 360mm unit, so thermal headroom shrinks when a high-power CPU runs sustained heavy loads. If cooling capacity is your top priority, consider whether a larger radiator fits your case before committing.
Liquid coolers also contain a pump and flexible tubing, so they are not as maintenance-free as a solid air heatsink. Case airflow and radiator fan orientation need to be planned together, otherwise the cooler cannot perform to its potential.
The ARGB fans add wiring, and boards with few ARGB headers may require a splitter or controller. Check your motherboard's header count before ordering.

FAQ

Q: Can I mount it on an LGA 1700 CPU without extra parts?
A: Yes. LGA 1700 is supported out of the box according to the product documentation, so no additional mounting kit is required.
Q: Does it work on AM5 motherboards?
A: The bracket covers AM5, AM4 and TR4, so AM5 builds can use it directly.
Q: Should I pick a 360mm radiator instead?
A: If your case has room for a 360mm radiator and you push a high-power CPU hard, the larger unit leaves more margin. For builds limited to 240mm, or where looks and price matter more, the M240 is the easier fit.
