This article covers Cooler Master 240 Core II ホワイト AIO CPU 液体クーラー.

Overview

The Cooler Master MasterLiquid 240 Core II White is a 240mm all-in-one CPU liquid cooler designed for mid-tower PC builds. Its key highlight is the patented G9R dual-chamber pump, which increases water pressure to directly target CPU hotspots. The cooler is optimized for AMD Ryzen 7 and Intel Core Ultra 7 / i7-class processors, offering a solid balance of quiet operation and thermal performance. Finished in white with an infinity mirror ARGB pump cover, this model appeals to builders who value aesthetics as much as cooling capability. The included MF120 Lite fans support daisy-chaining, simplifying cable management.

Connectivity & Compatibility

Socket support covers AMD AM5 / AM4 and Intel LGA 1851 / 1700. This means it works with the latest Intel Arrow Lake (LGA 1851), Raptor Lake Refresh (LGA 1700), and AMD Ryzen 7000/9000 series (AM5) out of the box. The pump uses a standard 3-pin connector, while the fans are controlled via PWM 4-pin headers. Fan speed ranges from 650 to 1,750 RPM, allowing you to prioritize silence or airflow depending on the workload.

Product Info

Released in early 2025, the MasterLiquid 240 Core II White sits in the mid-range AIO cooler segment. Its typical street price is around ¥18,000–¥20,000 in Japan. The package includes mounting kits for Intel and AMD sockets, a backplate, thermal paste, and all necessary screws. Warranty is the standard two years from Cooler Master. What sets this cooler apart in its price bracket is the dual-chamber pump design and the infinity mirror ARGB lighting, features usually found on more expensive models. It delivers strong value for builders who want above-entry-level cooling without jumping to a 360mm radiator.

Best Use Cases

Silent PC builders: The pump operates quietly even under load, and the fans are nearly inaudible at low RPM. Ideal for office or media-center PCs where noise matters. White-themed builds: Every visible component — radiator, pump, fans — is white. The infinity mirror ARGB adds a premium touch without overwhelming the build. Mid-range CPU cooling: Perfect for Ryzen 7 7800X3D or Core i7-14700K at stock settings. It handles moderate overclocking but isn't intended for extreme loads. Budget-conscious water cooling newcomers: If you want better performance than a basic 120mm AIO or a budget air cooler, this is a logical step up without breaking the bank.

Things to Consider

Make sure your case supports a 240mm radiator. The radiator itself is about 27mm thick, and with fans attached the total height reaches roughly 52mm. Check top or front mounting clearance before purchase. For high-end CPUs like the Core i9-14900K or Ryzen 9 7950X under sustained all-core loads, this cooler may struggle to keep temperatures in check. In such scenarios, a 280mm or 360mm AIO would be a safer choice. Also note that the pump cap's infinity mirror orientation is fixed — you cannot rotate the display direction independently. Depending on your mounting orientation, the logo might appear upside down. Plan your installation accordingly.
