Overview

The Cooler Master MasterLiquid ML240L RGB V2 is a 240mm all-in-one liquid CPU cooler built around three V2-generation improvements over the original ML240L: a redesigned third-generation dual chamber pump that reduces internal turbulence and improves coolant flow consistency; a larger radiator fin surface area that increases the heat exchange rate without requiring a physically larger radiator; and the inclusion of CryoFuze Violet thermal compound — a nanoparticle-composite paste rated at 12.6W/mK, which is a specification level typically found in aftermarket paste purchases rather than included compounds. Together, these changes produce measurable temperature improvements over the first-generation unit under sustained load. The SickleFlow 120 RGB fans complete the thermal package with an Air Balance blade geometry optimized for the static pressure demands of a 240mm radiator and rifle bearing construction for long-term quiet operation.

The ML240L V2 targets PC builders who want AIO liquid cooling aesthetics and performance at a mainstream price point — it's built for Ryzen 5/7 and Intel Core i5/i7 builds where the CPU's thermal output falls within the 150–180W sustained range that a quality 240mm AIO handles comfortably. The full RGB illumination on both the pump head and the SickleFlow fans, combined with certified motherboard RGB software compatibility, makes it a strong visual fit for windowed builds synced to existing AURA Sync, Mystic Light, or RGB Fusion setups. Platform coverage is comprehensive: AM5, AM4, LGA1700, and LGA1200 are the current-generation sockets, with legacy socket support extending the cooler's utility in secondary or repurposed builds. Pre-purchase verification of case radiator mounting positions (front or top 240mm) is the critical planning step before committing to this cooler.

Key Features

Violet Tinted Compound: Violet tinted thermal compound utilize nanoparticles developed by thermal engineers for superior composition

3rd Generation Dual Chamber Pump for overall cooling efficiency and performance, The larger surface area increased the surface area of the fins on the radiator for better heat dissipation. New dual chamber design improving the overall rapid cooling.

Full RGB Illumination: Light up your build with vibrant colors using the RGB pump and fans. Software compatible RGB lighting also certified for compatibility with major motherboard manufacturers.

New SickleFlow 120 RGB: Fan boasts optimized air balance fan blades for impressive airflow. The durable fan frame and premium rifle bearing design gives you performance with quiet operation.

Exceptional Conductivity: Thermal conductivity matching K value cooling requirements of 12.6W/mK handles even the most extreme builds.

Pros & Cons

👍 Pros

  • 12.6W/mK CryoFuze Violet nanoparticle thermal paste is well above the 4–8W/mK spec of competing AIOs' included compounds, reducing the thermal interface as a bottleneck from day one.
  • Third-gen dual chamber pump with enlarged radiator fin surface area provides measurable cooling efficiency improvement over its predecessor without increasing the physical radiator size or fan count.
  • Broad socket compatibility covering AMD AM5/AM4 and Intel LGA1700 through LGA2011 makes this a future-relevant cooler for builds across current and last-gen platforms.
  • Motherboard-certified RGB synchronization eliminates the need for a separate lighting controller or Cooler Master software — the pump head and fans integrate directly into existing AURA/Mystic Light/Fusion ecosystems.
  • SickleFlow 120 PWM fans with rifle bearings deliver quieter idle operation than sleeve-bearing alternatives, with PWM speed control scaling noise proportionally to thermal demand.

👎 Cons

  • 201mm radiator length requires a case with a 240mm top or front mounting position — compact mATX cases without a 240mm mount are incompatible, requiring case verification before purchase.
  • A 240mm single-row radiator has a defined thermal ceiling — under sustained all-core overclocking on high-TDP processors (200W+), performance trails 280mm and 360mm AIOs or high-end air coolers.
  • RGB tubing is absent — the lighting is limited to the pump head and fans, which may feel incomplete versus AIOs that also illuminate the tubing in visually prominent builds.
  • The pump assembly height (mounting standoffs) may conflict with tall memory DIMMs in tight LGA1700 builds where the pump head is mounted in close proximity to the first DIMM slot.
  • Cooler Master's included AM5 mounting solution compatibility should be verified at purchase — early production units sometimes required an additional bracket not included in the original box.

Frequently Asked Questions

The ML240L V2 supports AMD AM5, AM4, AM3+, AM2+ and Intel LGA1700, LGA1200, LGA115X, LGA1366, LGA2066, LGA2011-v3, and LGA2011. Mounting hardware for all listed sockets is included. For AM5 specifically, verify you're installing with the correct AM5 bracket — some early ML240L V2 units required a separate AM5 kit that Cooler Master made available.
The dual chamber design separates the suction and discharge sides of the pump, reducing internal turbulence and improving fluid delivery consistency. The redesigned radiator fin surface area in the V2 increases the heat exchange area compared to the previous iteration, which directly improves the rate at which heat is transferred from coolant to airflow through the radiator.
The SickleFlow 120 fans use a rifle bearing design for quieter long-term operation compared to sleeve bearings. Fan speed is PWM-controlled — the motherboard's PWM headers manage RPM based on thermal load, so noise under light workloads is significantly lower than at maximum RPM. Maximum RPM noise levels are not specified in the available data.
CryoFuze Violet is rated at 12.6W/mK thermal conductivity — achieved via nanoparticle composition. This is a high-performance spec that sits above most included compound in competing AIOs. Most thermal compounds, including nanoparticle formulations, perform optimally after 25–50 hours of thermal cycling (curing), so expect temperatures to settle slightly lower after initial break-in.
Yes — Cooler Master certifies the ML240L V2's RGB for compatibility with major motherboard manufacturers' RGB software ecosystems (ASUS AURA Sync, MSI Mystic Light, Gigabyte RGB Fusion, ASRock Polychrome). You can control pump head and fan RGB from within your motherboard's native software without requiring Cooler Master's MasterPlus+ application, though both options are available.
