Dual 140mm PWM fans with iCUE LINK hub

This dual pack delivers two 140mm PWM case fans that spin from 300 to 1700 RPM and push up to 95.7 CFM. Magnetic dome bearings keep noise between 10 and 36 dBA. The included iCUE LINK System Hub lets both fans connect through a single cable for tidy cable management. Builders who want a complete, ready-to-install cooling pair for a 140mm mount will find everything in the box.

Bridge connectors and hub simplify daisy-chaining

Each fan ships with an active and a passive connector that link directly to the next fan, forming a continuous chain back to the supplied hub. A 135mm slim-slim cable and a 600mm straight-slim cable give routing flexibility inside the case. The hub draws power from a PCIe cable and communicates over USB, so software control requires only one motherboard header. Users who prefer traditional individual headers cannot separate the fans without extra accessories.

3.79 mm-H2O static pressure for dense radiators

The RX series reaches 3.79 mm-H2O at maximum speed, making it suited for high-density radiators and restrictive heatsinks. AirGuide anti-vortex vanes focus airflow through the fins rather than around them. Eight RGB LEDs per fan illuminate through a side window in the frame. Buyers who need higher airflow at lower resistance or who want a thinner 25mm profile for tight clearances should check the specifications against their radiator thickness.

Questions about this item

How often will the magnetic dome bearings in these RX140 fans need replacement?

The magnetic dome bearing design eliminates physical contact between moving parts, so there is no scheduled replacement interval for the bearings themselves.

What limit appears first when the fans run at 1700 RPM for long periods?

At maximum speed the fans produce 36 dBA of noise, which is the most noticeable constraint before thermal or power limits are reached.

How much heat and power do the two fans and the iCUE LINK hub add when running all day?

The pair draws power through a single PCIe cable and the hub, while noise stays between 10 and 36 dBA depending on the PWM duty cycle set in iCUE.
