EK AIO 120mm vs CR240 Lux Specs
Radiator Size
The EK Nucleus CR240 Lux AIO Cooler features a 240mm radiator. This larger surface area allows for more heat dissipation compared to smaller units. In contrast, the EK AIO 120mm D-RGB Liquid Cooler uses a 120mm radiator. This is the smallest standard AIO size, designed for tight spaces. The CR240 offers significantly more cooling potential due to its double-fan setup. The 120mm unit is limited by its single fan and smaller core. For most builds requiring strong cooling performance, the larger radiator is the practical choice. You should select the CR240 if case space permits, as it handles heat loads better than the compact 120mm model.
Lighting Type
Both coolers feature addressable lighting, but they differ in control and effect. The EK AIO 120mm D-RGB Liquid Cooler uses D-RGB lighting built into the CPU block and Vardar S fans. You can customize colors via motherboard or a standalone controller. The EK Nucleus CR240 Lux AIO Cooler features Digital RGB lighting. It offers a stylish fan-like gradient effect on the pump unit. While both allow customization, the CR240 Lux emphasizes a specific aesthetic gradient on the pump. The 120mm model focuses on full RGB coverage across fans and block. Your choice depends on whether you prefer broad fan lighting or a distinct pump gradient effect.
Physical Dimensions
Size matters for case compatibility. The EK Nucleus CR240 Lux AIO Cooler measures approximately 19.7 inches in width and 11 inches in height. Its radiator dimensions are 281 x 124 x 27 mm. The EK AIO 120mm D-RGB Liquid Cooler is much smaller, measuring 8.27 inches in width and 10.2 inches in height. The 120mm unit fits easily into small form factor cases or tight CPU areas. The CR240 requires a case that supports 240mm radiators. If you have a compact build, the smaller dimensions of the 120mm model are essential. For standard ATX cases, the larger CR240 fits without issue.
Weight
Weight affects mounting stress and case support. The EK AIO 120mm D-RGB Liquid Cooler weighs 3.09 pounds. This is heavier relative to its size, likely due to the reinforced sleeved tubing and aluminum covers. The EK Nucleus CR240 Lux AIO Cooler weighs 2.2 pounds. Despite being twice the radiator size, the CR240 is lighter. This suggests more efficient material use in the CR240 design. A lighter cooler puts less strain on the CPU socket and motherboard bracket over time. The CR240 offers a better weight-to-size ratio. The 120mm model is denser, which may require careful handling during installation.
Socket Compatibility
Both coolers support major modern platforms. The EK Nucleus CR240 Lux AIO Cooler is compatible with Intel and AMD sockets. The EK AIO 120mm D-RGB Liquid Cooler supports Intel LGA 115X, 1200, 2066, and AMD AM4. It is LGA 1700 ready but requires a separate kit purchase. The CR240 data indicates broad compatibility without mentioning extra kits. If you are using the latest Intel LGA 1700 socket, the 120mm model needs an additional purchase. The CR240 appears to be more plug-and-play for newer sockets. Check your specific motherboard socket before buying, especially for the 120mm model if you have LGA 1700.
