RX120 vs LX140 Comparison
Fan Size
The Corsair iCUE Link RX120 RGB operates at a standard 120mm diameter, while the Corsair iCUE Link LX140 RGB uses a larger 140mm frame. This size difference affects how each fan fits into your case. The 120mm RX120 is a common size that fits most standard mounts. The 140mm LX140 requires more space but moves more air. You must check your case specifications to ensure the larger 140mm fan fits in your intended location. Both fans share the same 0.98-inch height, so depth is not a factor in this comparison. Choose based on your available mounting area.
Airflow
Airflow determines how much air moves through your system. The Corsair iCUE Link LX140 RGB delivers 84.6 CFM of max airflow. The Corsair iCUE Link RX120 RGB provides 74.2 CFM. The LX140 moves significantly more air per minute due to its larger blade surface area. This makes the LX140 better for general case ventilation where volume matters. The RX120 offers less total air movement. If your priority is moving large volumes of air across components, the LX140 has a clear advantage. The RX120 is sufficient for smaller spaces.
Static Pressure
Static pressure measures the force air exerts when pushing through obstructions like radiators or dense filters. The Corsair iCUE Link LX140 RGB generates 4.82 mmH2O of static pressure. The Corsair iCUE Link RX120 RGB produces 4.38 mmH2O. Higher static pressure is crucial for cooling radiators effectively. The LX140 exerts more force against resistance. This gives it an edge when mounting to high-density heatsinks. The RX120 is still capable for radiator use, but the LX140 is stronger in this metric. You should prefer the LX140 for radiator mounts.
Lighting
Both fans feature RGB lighting managed through the iCUE ecosystem. The Corsair iCUE Link LX140 RGB includes dual light loops with 18 LEDs per fan. This design creates a more complex and vibrant lighting effect. The Corsair iCUE Link RX120 RGB is also RGB-enabled, but the data does not specify the number of LEDs or loop configuration. The LX140 offers a distinct visual advantage with its dual-loop design. If custom lighting and brightness are important to your build, the LX140 provides superior visual details. Both sync with iCUE devices.
Speed
Fan speed impacts both cooling performance and noise levels. The Corsair iCUE Link RX120 RGB reaches a maximum speed of 2,100 RPM. The Corsair iCUE Link LX140 RGB tops out at 2,000 RPM. The RX120 spins faster, which can help in tight spaces or with smaller radiators. The LX140 moves more air at a lower speed, which can be quieter. The RX120 has a slight edge in maximum rotational speed. You might choose the RX120 if you need higher RPM for specific airflow constraints.
Packaging
The quantity of fans included changes how you buy and install. The Corsair iCUE Link RX120 RGB is sold as a triple pack containing three 120mm fans. The Corsair iCUE Link LX140 RGB is sold as a single pack containing one 140mm fan. You get more physical units with the RX120 purchase. This is useful if you need to fill multiple slots. The LX140 requires separate purchases for multiple fans. Consider your total fan count needs. The RX120 offers better volume for multi-fan builds.
Which Corsair iCUE Link Fan Suits You
Users needing high airflow for spacious cases
The 140mm LX140 delivers 84.6 CFM of airflow, significantly higher than the RX120. Its larger frame moves more air at a lower 2,000 RPM. This makes it ideal for open chassis layouts where maximum volume displacement is your priority. You get efficient cooling with less noise than smaller fans running at high speeds.
Builders installing fans on dense radiators
The 120mm RX120 generates 4.38 mmH2O of static pressure, helping push air through tight fins. While the LX140 has slightly higher pressure, the RX120 is a standard size for many compact radiator mounts. If your case or radiator slots are limited to 120mm, this triple pack offers a reliable, high-pressure solution for your build.
Users wanting value in a single purchase
The RX120 comes as a triple pack, giving you three fans for one unit. The LX140 is sold as a single fan. If you need to populate multiple slots in your case, buying the RX120 pack is more convenient. You get the same iCUE Link hub connectivity and RGB features, but with more fans included in the box.
