Overview
Corsair ships this pack so three fans can link together and connect to a motherboard through a single PWM header and a single ARGB header. Each fan carries anti-vortex vanes, and magnetic dome bearings support the rotor.
The reason to buy is simple wiring for three lit fans that can also serve a radiator. The limit is that lighting needs a plus five volt ARGB header on the board and the listing gives no frame dimensions beyond the size in the title.
Who it's for
Builders adding intake or radiator fans, who want lighting driven by the motherboard, will have an easy install. Anyone without the right headers, or who wants non-lit fans, should look elsewhere.
Pros and cons
- Daisy-chain reduces cable clutter
- Zero RPM mode at low loads
- Magnetic dome bearings
- Suitable for radiators
- Needs an ARGB header
- Louder at top speed
- Contents listed only as item
Performance notes
Zero RPM mode stops the fans at low temperatures so the system is silent at idle. Anti-vortex vanes direct the airflow, and static pressure lets the fans push through a radiator. Noise rises with rpm, so the fan curve in your motherboard matters.
