In this corsair icue link lx140 RGB review, we look at a single pack of 140mm PWM fans designed for precise thermal management. These units deliver 84.6 CFM of airflow and reach speeds up to 2,000 RPM. They feature dual light loops with 18 LEDs per fan for customizable illumination. The fans use AirGuide technology to direct airflow efficiently. You must connect them to an iCUE Link System Hub, which is sold separately. This setup allows for synchronized lighting and control through a single cable connection.
What stands out
- Dual Light Loops with 18 LEDs per fan
- Max airflow of 84.6 CFM at 2,000 RPM
- Static pressure of 4.82 mmH2O for radiator mounting
- Magnetic Dome Bearing for reduced friction and noise
- AirGuide Technology with anti-vortex vanes
Who it fits
Good fit for
This fan suits builders using the Corsair iCUE Link ecosystem who need high airflow for case ventilation or static pressure for radiators. The 140mm size fits standard cases and cooling blocks. If you want synchronized RGB lighting across multiple components, the dual light loops help. The magnetic bearing offers longevity and quiet operation. You will appreciate the streamlined cabling provided by the bridge connectors when paired with the required hub.
Who should skip it
Skip this option if you do not own or plan to buy the iCUE Link System Hub. This fan cannot operate independently without that hub. It is also unsuitable for builds requiring 120mm fans, as this is strictly a 140mm unit. If you prefer plug-and-play fans without a central hub, look elsewhere. The requirement for separate hub purchase adds complexity and cost to your build plan.
Verdict: The Corsair iCUE Link LX140 RGB is a solid choice for iCUE ecosystem users needing high airflow and pressure. It requires the separate System Hub to function.
Key specs explained for this fan
Fan Size: 140mm
This dimension refers to the width and height of the fan frame. A 140mm fan moves more air at lower speeds than smaller 120mm units. This results in quieter operation while maintaining effective cooling. You should verify that your PC case has mounting holes that match this size. Larger fans are generally preferred for intake positions where noise reduction is a priority.
Max Airflow: 84.6 CFM
CFM measures the volume of air the fan can push in one minute. A rating of 84.6 CFM indicates strong airflow capacity for cooling components. This specification is critical for intake fans that bring fresh air into your case. Higher numbers mean better ventilation for your graphics card and CPU. Compare this value with other 140mm fans to ensure adequate cooling for your specific build.
Max Fan Speed: 2000 RPM
RPM stands for revolutions per minute, indicating how fast the fan blades spin. A maximum of 2000 RPM allows the fan to reach peak performance when the system is under heavy load. This speed works in tandem with PWM control for precise thermal management. You will notice increased noise at this maximum speed. It is useful for short bursts when temperatures spike during intensive tasks.
Static Pressure: 4.82 mmH2O
Static pressure measures the fan's ability to push air through resistance. A value of 4.82 mmH2O allows the fan to work well against dense obstacles. This makes the fan suitable for mounting on radiators or through dust filters. If you are building a liquid cooling loop, this spec ensures efficient heat transfer. Higher static pressure is generally more important than raw airflow for these specific applications.
Bearing Type: Magnetic Dome
The bearing type determines the internal mechanism that supports the fan shaft. A Magnetic Dome bearing uses magnetic levitation to reduce friction. This design aims to minimize noise and extend the lifespan of the fan. Less friction means the fan can run smoother for a longer period. This is a practical choice for users who want reliable long-term operation without frequent replacements.
Design and Build Analysis
The Corsair iCUE Link LX140 RGB fan measures 5.51 by 5.51 inches with a height of 0.98 inches. It weighs 8.11 ounces. These dimensions fit standard 140mm mounting spaces in most PC cases. The listing specifies a black finish for the frame. You should verify that your case has compatible mounting holes before installation. The physical footprint is compact enough to fit in tight spaces without obstructing other components.
Airflow management relies on Corsair AirGuide Technology. The listing notes anti-vortex vanes that direct air toward hot components. This design concentrates airflow for more efficient cooling. The fan uses a Magnetic Dome bearing. This bearing type reduces friction and noise while extending the product's lifespan. It is a refinement of magnetic levitation technology. You get precise speed control via PWM. The listing states maximum speeds reach 2,000 RPM.
The build includes iCUE LINK bridge connectors. These allow you to link fans directly to each other. A single cable then connects the entire bank to the iCUE LINK System Hub. Note that the hub is sold separately. This setup simplifies cable management inside your case. You avoid a cluttered mess of individual fan cables. The dual light loops contain 18 LEDs. They provide customizable RGB lighting. This lighting syncs with other iCUE devices. The design prioritizes clean aesthetics and organized wiring for your build.
Setup and everyday use
Installing these fans requires a specific ecosystem. The listing notes that the iCUE Link System Hub is sold separately. You must connect this hub to your motherboard and power supply to operate the fans. The package includes iCUE LINK bridge connectors. These allow you to daisy-chain multiple fans together. This setup uses a single cable to connect the entire fan bank to the hub. This reduces cable clutter inside your case compared to traditional PWM wiring.
Daily use relies on your system software. You control the fan speeds and RGB lighting through the iCUE application. The fans support PWM control, allowing you to adjust speeds up to 2,000 RPM. At lower speeds, the Magnetic Dome bearing minimizes noise. At higher speeds, the fan delivers 84.6 CFM of airflow. The 4.82 mmH2O static pressure helps when mounting these units to radiators or dust filters.
The dual light loops feature 18 LEDs per fan. You can customize these lights to sync with other iCUE RGB devices. The AirGuide technology uses anti-vortex vanes to direct airflow efficiently. This design concentrates cooling on hot components. The bearing type suggests reduced friction and greater longevity. You do not need to adjust hardware settings manually. All tuning happens digitally through the software interface.
What You Need To Know
You need to verify case compatibility before purchasing. This 140mm fan requires a mounting space with a 140mm hole. Many mid-tower cases only accept 120mm fans. Check your case specifications to ensure it supports 140mm intake or exhaust positions. You must also purchase the iCUE Link System Hub separately. This hub is essential for controlling the fans and lighting. Without it, the fans will not operate. The included bridge connectors allow you to link multiple fans together. This simplifies cable management but does not replace the hub. Regular upkeep involves dusting the blades and vanes. Use compressed air to clear debris from the anti-vortex vanes. This maintains the 84.6 CFM airflow rating. The magnetic dome bearing reduces friction, but dust buildup can increase noise over time. Keep the area around the fan clear for optimal airflow. Consider this option if you already own Corsair iCUE Link components. It integrates seamlessly with other RGB devices in your build.
Check before you buy
- Verify your PC case supports 140mm fan mounting holes
- Purchase the separate iCUE Link System Hub for control
- Check if your motherboard has available iCUE Link headers
- Ensure you have space for the hub inside the case
