Running out of PWM sockets and running out of ARGB sockets require separate checks

Running out of somewhere to plug a fan and running out of somewhere to plug a lighting device are two completely separate shortages, and mixing them up when planning a build is how an order lands with nowhere for half of it to go. Counting PWM and ARGB sockets separately, before ordering anything, avoids that specific headache.

Quick Answer

Fan connections and addressable lighting connections are counted independently on almost every motherboard, since the two systems use entirely different header types. A build can have plenty of free PWM sockets and none left for ARGB, or the reverse, because the two counts have nothing to do with each other. Checking both totals against what an order actually needs, before it arrives, is what keeps AsiaHorse fans, hubs, and cables - priced from R199 through R699 - from ending up with no header to plug into.

🔢 Why the two counts diverge so easily

A four-pin PWM fan header and a 5V three-pin ARGB header serve completely different systems, and motherboard manufacturers do not necessarily provide them in matching numbers - a board can be genuinely generous with fan headers while offering only two or three addressable headers, or the other way around depending on the model and price point. Assuming the two totals will roughly match is a reasonable-sounding guess that turns out wrong often enough to be worth checking properly instead.

Which one typically runs out first

That varies by board and by build, though addressable headers are often the scarcer of the two on many motherboards, since PWM fan headers tend to be provided more generously across most price points.

🔌 The options once a count runs short

Splitters and hubs extend PWM fan connections; chaining devices together, alongside hubs, extends addressable connections. The AsiaHorse ASH-S1 addresses both shortages at once, adding nine PWM fan ports and nine 5V three-pin ARGB ports as two entirely separate banks on one SATA-powered unit.

Does chaining work the same way for every fan

Not consistently - some fan families in this range chain their speed connections between units on one cable run, while others give each individual fan its own separate lead. Which approach a specific model uses is stated directly in its product description, worth checking before assuming a row of fans will daisy-chain the way a previous purchase did.

📋 Keeping the two counts on paper

List PWM and ARGB requirements separately before ordering, rather than as one combined figure, since that is exactly what makes a genuine shortage visible before assembly begins rather than partway through it. Cable routing to support either connection type is in the cable solutions range.

Frequently Asked Questions

Why are fan and lighting sockets counted separately?

Because fan speed and addressable lighting use entirely different header types, so a board can be generous with one and short of the other.

Which type typically runs short first?

That depends on the specific build, though addressable headers are often fewer in number than fan headers on many motherboards.

What are the options once a socket count runs short?

Splitters and hubs for fan connections, and chaining plus hubs for lighting connections, with the ASH-S1 covering both needs at once.

Does chaining work the same way across every fan family?

No - some fan families chain their speed connections together while others give each individual fan its own separate cable lead.

How do I know which fans in a range chain and which don't?

The product description states it directly, usually noting either linked connectors between units or a separate cable per fan.

Should the two counts be listed together or separately?

Kept separate, since that is what makes a genuine shortage visible before ordering rather than discovered partway through assembly.

Does a hub solve both shortages at once?

The ASH-S1 does, carrying nine PWM fan ports and nine addressable ARGB ports as two clearly separate banks on one unit.
