Overview
A tower build that wants matched lighting across the front, top and rear gets three fans in one box. The reverse blade layout and ARGB lighting are the two features named in the title, along with PWM control.
A matched trio makes planning simple, because every fan in the case uses the same blade style and lighting. The limit is the listing itself, which omits speed, airflow, noise level and cable information.
Who it's for
A showcase build with several fan slots to fill on the front or radiator. Cooling-focused builders should confirm the numbers with Lian Li before committing.
Pros and cons
- Three fans in one pack
- PWM speed control
- Reverse blade layout
- Airflow and noise not listed
- Cable and connector details unlisted
- Controller or hub inclusion unlisted
Performance notes
With PWM, the motherboard raises or lowers the rotation speed, which trades airflow for noise. Reverse blade orientation places the blade curve on the opposite side from a standard fan, which changes how the lighting and the airflow face the case. The listing gives no figures for either, so results depend on the case and the fan curve.
