RX120 MAX vs LX140-R RGB Specs
Fan Size and Airflow
The Corsair iCUE Link RX120 MAX uses 120mm fans to deliver 71.3 CFM of airflow. These fans spin up to 2,000 RPM. The Corsair iCUE Link LX140-R RGB features larger 140mm fans. These larger blades move 90.6 CFM at the same 2,000 RPM limit. The 140mm design moves significantly more air per rotation. This makes the LX140-R better for high-volume cooling needs. The RX120 MAX is smaller and fits in tighter spaces. You get more air with the LX140-R RGB.
Static Pressure
Static pressure measures how well a fan pushes air through dense obstacles like radiators or filters. The RX120 MAX provides 4.16mm-H2O of static pressure. The LX140-R RGB offers 4.22mm H2O. The difference is small but measurable. The LX140-R has a slight edge in pushing force. Both fans use magnetic dome bearings to reduce friction. This helps maintain speed under load. The LX140-R is marginally better for heavy radiator setups.
RGB Lighting Setup
Lighting visibility differs between the two models. The RX120 MAX has eight RGB LEDs and a window in the frame. This allows side viewing of the lights. The LX140-R RGB uses dual light loops with 18 LEDs per fan. This creates a brighter and more uniform glow. The LX140-R also features a reversed rotor. This keeps the RGB ring visible even during intake. The RX120 MAX relies on a frame window. The LX140-R offers superior lighting aesthetics.
Physical Dimensions
Size matters for case compatibility. The RX120 MAX fans are 1.18 inches thick. The LX140-R RGB fans are 0.98 inches thick. The LX140-R is thinner, which helps in tight cases. The RX120 MAX is thicker, which may aid in structural rigidity. Both fit standard mounting holes. The LX140-R is wider at 5.51 inches compared to the 4.72 inches of the RX120 MAX. Check your case clearance for the larger 140mm footprint.
Package Contents
You get different quantities with each package. The RX120 MAX comes as a 3-pack of 120mm fans. The LX140-R RGB is a dual fan kit of 140mm fans. Both include iCUE Link bridge connectors. This allows daisy-chaining to the System Hub. The RX120 MAX gives you more fans for the same connectivity method. The LX140-R gives you larger fans in a smaller number. Consider how many fans you need for your case.

Users needing high static pressure for radiators
The RX120 MAX delivers 4.16mm-H2O of static pressure. Its thicker 5mm blades move more air at lower speeds. This design helps push air through dense radiator fins efficiently. You get precise PWM control up to 2,000 RPM. The included system hub connects all fans via a single cable for clean management.
Builders prioritizing maximum airflow and aesthetics
The LX140-R RGB offers 90.6 CFM of airflow, significantly higher than the RX120 MAX. Its 140mm fans provide 4.22mm H2O of static pressure. The reversed rotor design keeps the RGB ring visible during intake. Dual light loops with 18 LEDs per fan create a striking visual effect synchronized with other iCUE devices.
Those wanting quieter operation at same speed
The RX120 MAX uses thicker blades to enhance cooling. This allows the fan to spin slower while maintaining airflow. Lower speeds generally result in reduced noise levels. You still get full RGB lighting and magnetic dome bearings. The single-cable iCUE Link connection simplifies setup while keeping your case interior tidy and quiet.
