Know before you buy
Yes, this fan requires the CORSAIR iCUE LINK System Hub to function. It is designed as an expansion unit for existing iCUE LINK setups, so you must have the hub already installed in your system.
No, this fan uses a proprietary iCUE LINK connector rather than a standard 4-pin PWM header. It must be connected to the iCUE LINK System Hub to receive power and control signals.
Absolutely. With a high static pressure of 3.79 mmH2O and AirGuide technology, this fan is specifically engineered to push air effectively through the dense fins of a radiator.
The Magnetic Dome bearing reduces friction compared to traditional sleeve or ball bearings. This results in quieter operation, increased longevity, and better performance over the life of the fan.
Yes, the fan supports Zero RPM mode. When your system is under low load and temperatures are cool, the fan will stop spinning entirely to provide complete silence.
You can connect multiple fans together using the included bridge connectors, which simplifies cable management significantly. However, the total number of devices is limited by the power capacity of your iCUE LINK System Hub.
