This article covers Cooler Master PL240 Flux ARGBクーラー.

Overview

The Cooler Master MasterLiquid PL240 Flux is a 240mm all-in-one liquid CPU cooler featuring dual ARGB fans and a slim radiator. It's designed for users who want strong thermal performance without sacrificing case compatibility or visual flair. The cooler targets the mid-to-high-end CPU segment, handling chips like the Core i5-13600K and Ryzen 7 7700X with ease. What sets the PL240 Flux apart is its air-balance fan design, where the fan blades are connected at the outer ring for stable high-speed rotation and improved static pressure. Combined with a high-density fin radiator and a micro-channel copper cold plate, this cooler delivers efficient heat dissipation in a compact 240mm form factor.

Connectivity & Compatibility

The PL240 Flux supports Intel LGA1700/1200/115x and AMD AM5/AM4 sockets, covering virtually all modern desktop platforms. The pump connects via a standard 3-pin fan header, while the two 120mm fans use 4-pin PWM for speed control. ARGB lighting is managed through a 3-pin 5V addressable RGB header, allowing synchronization with motherboard software like ASUS Aura Sync, MSI Mystic Light, and Gigabyte RGB Fusion. Radiator dimensions are 277 x 120 x 27mm, fitting most mid-tower cases that support 240mm radiators. However, always check your case's radiator clearance, especially for top-mount installations where RAM or VRM heatsinks may interfere.

Product Info

Released in 2022, the MasterLiquid PL240 Flux carries a street price of around ¥16,800 in Japan. It comes with a 5-year warranty for official Japanese market units, which is longer than many competitors. The package includes mounting kits for Intel and AMD, pre-applied thermal compound, and fan extension cables. Market positioning is upper-mid-range. While it's priced slightly above entry-level 240mm AIOs, the PL240 Flux justifies the cost with its unique air-balance fans, micro-channel cold plate, and long warranty period.

Best Use Cases

Gamers building a mid-range to high-end PC: The PL240 Flux is an excellent match for CPUs like the Core i5-13600K or Ryzen 7 7700X, providing ample cooling for gaming and everyday multitasking. The ARGB fans add a polished look to any gaming build. However, for flagship CPUs like the Core i9-13900K or Ryzen 9 7950X under sustained all-core loads, a 280mm or 360mm radiator would be a safer choice. Users who prioritize quiet operation: The air-balance fans move plenty of air at low RPM, keeping noise down during idle and light workloads. The ceramic-bearing pump is also notably quiet. At full speed (2300 RPM), fan noise reaches 32 dBA, which is audible but not intrusive. Adjusting the fan curve in BIOS can further optimize the noise-to-performance balance. * Enthusiasts who want customizable RGB lighting: Both fans and the pump head feature ARGB LEDs that can be synced with the motherboard's lighting ecosystem. This makes it easy to create a cohesive color scheme. Note that if your motherboard lacks a 3-pin ARGB header, you'll need a separate controller.

Things to Consider

Before buying, verify that your case supports a 240mm radiator in your preferred mounting location. Top-mount installations may conflict with tall RAM modules or VRM heatsinks on some motherboards. The pump block height is approximately 52mm, which could be an issue in ultra-slim cases. Direct competitors include the NZXT Kraken X53 and Corsair H100i RGB PRO XT. The PL240 Flux offers quieter fans and a longer warranty (5 years vs. 3-5 years for rivals). However, NZXT and Corsair provide more polished software for fan and pump control, which may matter if you want granular tuning. Cooling performance is broadly similar across all three, so your choice may come down to aesthetics, software preference, or warranty length.
