A three-pack covers three positions neatly, until a build grows a fourth position after the pack has already been ordered. Working out where the extra Amici 5GT actually plugs in takes a moment of thought, since its two cables do not behave the same way.

Quick Answer

A fourth Amici 5GT fan links its ARGB lead into the end of the existing three-fan chain, since the product description allows linking across three to four fans, putting a fourth right at the top of that range. Its 4-pin PWM cable is a separate matter entirely and needs its own fan header or a splitter, since speed cables never chain between fans on this model.

The lighting connection

Adding a fourth fan to the lighting side means running its ARGB lead to the last fan already in the chain, extending the run by one link. Because the stated range tops out at four, this fourth fan sits at the edge of what the product supports rather than comfortably inside it, which is worth knowing if a fifth fan is ever considered later.

The speed connection

The PWM side works independently of the lighting chain. The fourth fan's 4-pin cable needs to reach a fan header of its own, or join a splitter alongside the other three, since none of the Amici 5GT's speed cables link fan to fan the way the ARGB leads do. This is the step that is easy to overlook when a build has been thinking in "lighting chain" terms rather than counting header connections separately.

Matching the new fan to the row

If the three original fans came from a three-pack in a particular colour and blade direction, keeping the fourth fan visually consistent means buying the same colour and direction as a single. Black and white cost the same, and standard and reverse blade cost the same, so matching the row does not carry a price penalty, only the requirement to pick the right listing.

Does the fan curve apply automatically?

Only if the fourth fan shares a header with the existing three. Wired to its own header or splitter, it needs its own curve set in software, since a fan curve applies per header rather than following the lighting chain it happens to be linked into.

Frequently Asked Questions

Where does the fourth fan's lighting lead connect?

Into the end of the existing three-fan chain, since the product description allows linking across three to four fans.

Does the fourth fan need its own fan header?

Yes, or a shared splitter position - each Amici 5GT's PWM cable runs independently of the lighting wiring.

Is adding a fourth fan within what the product actually supports?

Yes, four is the top of the stated range for ARGB linking, so it is supported rather than pushing beyond what is described.

Would a fifth fan work the same way?

The description specifies three to four fans, so a fifth sits outside what has been stated for this model and would need its own chain instead.

What does adding a fourth single cost?

R199, the standard single price, which is the usual way to extend a row that started as a three-pack.

Does the fourth fan need to match the original three visually?

For a consistent look, yes, matching colour and blade direction. It is not required for the fan to function, only for the row to appear uniform.

Where can I find the matching single for an existing three-pack?

Evetech's case fans listing carries the current single and pack options, and case accessories covers splitters if the header count is tight.
