This article covers Cooler Master 水冷CPUクーラー MASTERLIQUID 240 Core II [ MLW-D24M-A18PA-R1 ].

Overview

The Cooler Master MASTERLIQUID 240 Core II (model MLW-D24M-A18PA-R1) is a 240mm all-in-one liquid CPU cooler built around a dual-chamber pump and two 120mm fans. It supports Intel LGA1851, 1700, 1200, 1156, 1155, 1151, 1150 and AMD AM5/AM4 sockets, covering virtually every mainstream desktop platform available today. With a rated cooling capacity of 260W, it sits in the entry-to-mid range of the AIO market while still leaving headroom for higher-TDP processors. The fans spin from 650 to 1750 RPM, generating up to 70.5 CFM of airflow while keeping maximum noise at 30 dBA. The pump cap uses an infinity mirror finish, which gives the build a clean visual centerpiece without requiring a separate RGB controller. For anyone coming from a large tower air cooler, this is a practical and stylish step into liquid cooling.

Connectivity & Compatibility

The supported socket list is clear from the package: - Intel: LGA1851 / 1700 / 1200 / 1156 / 1155 / 1151 / 1150 - AMD: AM5 / AM4 Connection is made through a standard 4-pin fan header on the motherboard, so the pump and fans rely on board-side PWM control. If your BIOS supports fan curves, you can easily tune idle behavior for lower noise. Since the radiator measures 277 x 119.2 x 27.2 mm, the case needs room for a 240mm radiator — typically at the top or front — or at least a mounting point for two 120mm fans. AMD installation uses the standard AM5/AM4 backplate, while Intel builds use the socket-specific mounts included in the box. The process is straightforward enough for first-time AIO users, though checking case clearance before purchase is always recommended.

Product Info

The MASTERLIQUID 240 Core II belongs to Cooler Master's Core series and is positioned as an entry-to-mid tier 240mm AIO. It brings features found higher up the lineup, such as a dual-chamber pump and an infinity mirror cap, while keeping the package affordable. The observed street price in Japan is around ￥15,000, which makes it a strong value pick for buyers who want balanced cooling without moving to a bigger 360mm unit. The cooler carries a 5-year warranty, which is reassuring for a liquid-cooling product. The box includes two 120mm fans, mounting kits for both Intel and AMD, and all the screws needed for a normal desktop install. Because it does not use a proprietary controller, cable routing stays tidy and setup feels predictable.

Best Use Cases

  • First-time AIO buyers: The 240mm form factor keeps case requirements modest, and the socket list covers both Intel and AMD platforms, so the risk of buying the wrong revision is low. The 260W rating provides a comfortable margin for midrange CPUs. Not ideal for users who are extremely sensitive to any pump noise, since liquid coolers behave differently from air coolers in that regard. - Gamers who want looks and quiet operation: The infinity mirror pump cover stands out in a glass-sided case, while the 30 dBA maximum fan noise helps keep long sessions comfortable. It needs no separate RGB ecosystem, which simplifies setup. Overclockers chasing maximum frequency on flagship CPUs may find the 260W class limiting and should consider a 360mm or higher-tier model. - Builders moving to Intel LGA1851: The cooler supports the newest Intel socket as well as LGA1700, so it works for both fresh builds and platform upgrades with the same mounting kit. That flexibility makes it a sensible choice for cost-conscious builders. Anyone planning a move to HEDT or workstation sockets, such as TRX50, should verify support before buying. - Air-cooler users dealing with RAM clearance: A tall tower cooler can overhang memory slots, but relocating cooling to a radiator frees up space around the socket. This makes memory swapping, M.2 access, and cable routing easier in compact builds. Users in very small ITX cases that cannot fit a 240mm radiator will be better off with a 120mm AIO or an air cooler.
