Overview
Chaining the three fans to the single controller reduces the number of cables in a case, and a mirror effect in the frame creates the infinity look. A fluid dynamic bearing carries each rotor, and the supplied controller handles the pack.
Choose it for a lit, tidy cooling upgrade that comes with its controller. The limit is that the controller is not wireless, the two airflow figures disagree, and the listing does not show how many fans one controller can chain.
Who it's for
A case builder with a glass panel, wanting synchronized lighting and tidy wiring, will use the daisy-chain design and the controller. Buyers who want remote control, or a simple unlit fan, should choose differently.
Pros and cons
- Infinity mirror lighting
- Fluid dynamic bearing
- Low stated noise
- Three fans in the pack
- Controller is not wireless
- Airflow listed two ways
- Chaining limit not listed
- Short warranty term
Performance notes
Fans move air in proportion to speed, with static pressure deciding how well they push through radiators or dust filters. Lower speeds cut noise, and the stated maximum noise applies at top speed. The lighting and the fans run from separate voltages, which the controller handles.
