Lighting and speed are separate systems, so board software can dim the ring while the fan curve carries on unchanged. The 5V connection carries only light. Nothing about brightness has any bearing on how fast the fan turns or how much it cools.
Two entirely separate systems run inside a single Amici Pro fan, and understanding that split answers a question that comes up often - can the ring go dim without the fan itself slowing down? Yes, and knowing why makes tuning a build's lighting and cooling independently far more straightforward.
The Amici Pro's ring lighting and fan speed are driven by entirely separate connections - the fan sells as a 3-pack at R399 including VAT, a price that is not locked in and can move - so motherboard software can dim or brighten the ring while the PWM fan curve continues running exactly as configured. Nothing about brightness has any bearing on how fast the fan spins.
The ring connects over a 5V 3-pin addressable header, carrying only lighting signal and power for the LEDs. The motor runs on a separate four-pin PWM connection to a standard fan header, carrying the speed control signal entirely independently. These are genuinely different physical connections on the fan, which is exactly why one can be adjusted without touching the other.
Your motherboard's RGB application handles the addressable header and therefore the ring's brightness, colour, and effects - the fans sync over a standard connection rather than needing a dedicated AsiaHorse utility. Fan speed, meanwhile, is set through your board's fan control panel or BIOS curve settings, entirely separate software from whatever runs the lighting.
Marginally, though addressable lighting draws a genuinely small load compared to the rest of a build, so the real reason to dim the ring is appearance rather than any meaningful power saving. If a build is chasing a subtler look, dimming through the RGB app is the right lever, not something that meaningfully changes overall system consumption.
Where your motherboard's RGB software offers an off state, yes - and the fan continues spinning at whatever speed the PWM curve dictates, completely unaffected by the lighting being disabled. This confirms just how separate the two systems genuinely are.
If the ring goes dark unexpectedly, check the RGB software's chosen effect first, since some effects genuinely include an off phase by design rather than indicating a fault. If that rules it out, the 5V 3-pin connection at the fan is the next thing to check - a partially seated connector is a common cause of no lighting signal reaching the fan. Genuine hardware failures within the covered period fall under the 1 Year Local Warranty, once connection issues have been ruled out. Browse case fans for the full range, and case accessories for extension cabling if your build needs a longer run to the header.

Yes, where your RGB software offers an off state, and the fan continues running exactly as the PWM curve dictates.
No, the two are driven separately, so a fan at full speed and one at idle look identical in terms of lighting.
