A stated wiring limit and an available header allowance sound like the same thing, but treating them as one figure is how a chain that reads fine on the box specification ends up overloading a header the manufacturer never described in the first place.

Quick Answer

The Amici 5GT product description limits ARGB linking to three or four fans. That figure describes the chain the fan itself supports; it says nothing about how many fans a specific motherboard header can safely power, and no universal header allowance is given anywhere in the product's own specification. The board's own documentation governs that second, separate limit.

Two different questions, one easily mistaken for the other

"How many fans can be linked together" and "how many fans can a header supply power to" sound like the same question, but they are answered by two different documents. The Amici 5GT's product listing answers the first: three to four fans on one ARGB chain. It does not, and is not meant to, answer the second, which depends entirely on the specific motherboard being used.

What the stated chain limit actually describes

Three to four fans is a property of the product: how far a signal reliably passes along the linked ARGB leads before the chain reaches its described limit. It has nothing to do with how much current any particular header can supply, since the fan manufacturer has no way of knowing which board a buyer will pair it with.

What governs the header side

The motherboard's own specification sheet or manual states what current each addressable header is rated to supply, typically in amps or milliamps. That figure is set by the board manufacturer, not by AsiaHorse, and it is entirely independent of how many fans the Amici 5GT's own description says can be chained together.

Can both limits bind at the same time?

Yes, and this is the situation worth planning around. A chain of four fans, sitting comfortably within the product's stated three-to-four range, can still exceed what a specific header is rated to supply, particularly if the header is older or lower-capacity, or if something else is drawing from the same connection. Passing one check does not guarantee passing the other.

What else can share a header's current budget

Any lit device connected to the same addressable header counts toward its total draw, not just fans. A strip of ARGB lighting, a lit cable cover, or any other addressable accessory sharing the same header reduces the current available for the fan chain, even if the fans alone would have fit comfortably.

Splitting a build across separate headers

Where a build's total ARGB load, fans and any other lit accessories combined, risks exceeding one header's rating, splitting the load across two or more addressable headers is the standard answer. Most current motherboards provide more than one, specifically to accommodate builds larger than a single chain or header can support on its own.

Does the speed side have an equivalent second limit?

Yes. Fan headers carry their own current ratings too, which becomes relevant mainly when a splitter is driving several fans from one physical header connection. That is a separate consideration from the ARGB header limit discussed here, governed by the fan header's own specification rather than anything to do with lighting. Check Evetech's case fans section for the current Amici 5GT range, plus case accessories for splitters worth checking against a board's stated ratings before committing to a layout.

Frequently Asked Questions

What does the stated three-to-four fan limit actually describe?

How many of these fans the product description supports linking together on one ARGB chain, a property of the fan rather than of any specific board.

What governs whether a header can actually supply that many fans?

The motherboard's own specification, which states the current each addressable header is rated to supply, published in the board manual or spec sheet.

Can a chain within the fan's stated range still overload a header?

Yes, a four-fan chain sitting inside the product's own three-to-four range can still exceed what a particular header is rated to supply, depending on the board.

Where is a board's header current rating published?

Typically in the motherboard manual or its own specification sheet, usually alongside descriptions of each header type.

Does anything besides fans draw from the same addressable header?

Yes, any lit accessory connected to the same header, such as a strip or cable cover, counts toward the same current budget as the fans.

How should a larger build be split to stay within both limits?

Across separate addressable headers, which most current motherboards provide specifically for builds exceeding one chain's or header's individual capacity.

Does the PWM side have a similar dual-limit situation?

Yes, fan headers carry their own current ratings too, most relevant when a splitter is driving several fans from a single physical connection.
