Water cooling Xigmatek LK 240 Digital Water Cooling LED Display A-RGB - EN45929

The Xigmatek LK 240 Digital Water Cooling LED Display A-RGB water cooling is a 240 mm AIO solution aimed at mid-range and more powerful gaming and creative configurations. It combines a dual 120 mm radiator with a digital accent and A-RGB lighting to keep temperatures under control without sacrificing aesthetics. It supports a wide range of CPU sockets – from older Intel LGA 115x to LGA 1700 / LGA 1851, as well as AMD AM4 and AM5, so you can use it confidently for future upgrades. The high airflow fans with adjustable speeds between 600 and 2000 RPM give you flexibility between silence and performance.

What you get is a classic 240 mm water radiator that shares heat between two 120 mm fans with a thickness of 25 mm – a good balance between cooling capacity and compatibility with most mid-tower cases. With up to 165.6 CFM total airflow, the fans can expel quite warm air, which helps under higher CPU loads. The range of 600–2000 RPM allows you to set profiles through BIOS or software – low speeds for quiet idle and high speeds during rendering, compiling, or longer gaming sessions. Connection is made with 4-pin connectors for PWM control and 5V ARGB for synchronizing the lights with other components.

• 240 mm radiator provides a larger area for heat dissipation compared to 120 mm AIO and is a good step for cooler and more stable CPU under long loads.
• Two 120 x 120 x 25 mm fans combine standard format for easy installation with sufficient thickness for good pressure through the radiator.
• Speed 600–2000 RPM allows a wide range from quiet operation to aggressive cooling, depending on whether you are chasing low noise or maximum thermal reserves.
• Airflow 165.6 CFM provides serious capacity for expelling hot air through the radiator, useful for higher TDP CPUs and warm cases.
• Noise level up to 29.8 dBA is a reasonable compromise for a 240 mm AIO with high airflow, especially if you set smarter fan curve profiles.
• Support for AM4, AM5, LGA 115x, LGA 1200, LGA 1700, and LGA 1851 means you can use it on almost any modern platform, as well as for future upgrades.
• 4-pin PWM and 5V ARGB connectors give you full control over speeds and the ability to synchronize lighting with the motherboard and other A-RGB components.

Who it is suitable for – for gamers and enthusiasts who want better cooling than a standard air cooler without switching to larger and bulkier 360 mm solutions. It is suitable for mid-range and stronger CPU configurations for gaming and productivity, where stable temperatures and reasonable noise are important. If you are aiming for a completely silent build under full load or have an extreme high-end CPU with very high TDP, you might want to look at a larger radiator.

The combination of 240 mm format, high CFM, wide RPM range, and rich compatibility with sockets makes this model a practical choice for a modern gaming or work PC with an emphasis on balancing cooling, noise, and aesthetics.
