Alphacool Rise Aurora 140mm White Fan

This 140mm case fan uses a 4-pin PWM connector for speed control. It features twenty individually addressable 5V aRGB LEDs in the frame and hub. The recessed diffusers spread light evenly across the entire fan. It is designed for system builders who want strong illumination and adjustable airflow.

PWM Control and Silent Operation

The fan runs from 0 to 2500 rpm via PWM and includes a silent mode that keeps it stopped until 350 rpm is required. At 800 rpm operation is nearly inaudible. Maximum speed delivers 118.9 m3/h airflow with 3.17 mm/H2O static pressure. Corner decouplers with foam pads reduce vibration transfer to the chassis.

Radiator and Case Cooling With RGB

Suitable for water-cooling radiators or standard case intake and exhaust positions. The 25mm thickness fits typical mounting points. Buyers who need a non-LED fan or a different voltage standard should consider other options.

Questions about this item

Will the 140mm frame and 25mm thickness fit my case fan slots?

The fan measures 140mm square and 25mm thick, so it fits any standard 140mm mounting location with the same depth clearance.

How do I connect the 4-pin PWM and 5V aRGB cables correctly?

Plug the 4-pin PWM lead into a motherboard fan header and the 3-pin 5V aRGB lead into a matching 5V addressable RGB header; reversing the aRGB plug will prevent lighting control.

What upkeep does the 2500rpm motor and 20 LED array need over time?

Dust the blades and frame every few months with compressed air; the decoupler pads and sealed bearing require no lubrication or scheduled replacement.
