Do I need a fan hub or a fan controller?

Choose a hub if you've simply run out of motherboard fan headers and want the board to keep controlling speed automatically — it powers many fans from one header. Choose a controller if you want to set fan speeds manually yourself, often via a dial or display. Many builders only ever need a PWM hub.

How many fans can a fan hub run?

It depends on the hub — most support a set number of fans and draw power directly (often via a SATA connector) so they aren't limited by a single header's output. Check the hub's stated fan count and connectors. A powered hub is the safe way to run many fans; a bare splitter off a header has a much lower limit.

Can I split one fan header to run two fans?

Yes — a fan splitter runs two (sometimes three) fans from a single header, which is fine for a couple of extra fans. Just don't chain too many onto one header, as it can only supply so much power. For four or more fans, a powered hub is the better choice.

What's the difference between a PWM and a DC fan hub?

A PWM hub passes the motherboard's precise 4-pin speed control to every fan plugged in, so they all ramp and idle together smoothly. A DC hub adjusts speed by voltage, which is coarser. If your fans are PWM, use a PWM hub fed from a PWM header to keep that fine control across all of them.

Can I control fan speed with software?

Often yes — many motherboards control connected fans through their own software or BIOS fan curves, and some controllers and hubs add their own app for finer control or monitoring. Capability varies by product, so check the specific item. If software control matters to you, confirm it's supported before buying rather than assuming.

Will a fan controller make my PC quieter?

It can — by setting a sensible speed or fan curve, you stop fans running flat out when there's no heat to clear, which is usually the main source of noise. Pair that with PWM fans and you get near-silent idling that only ramps up under load. Controllers don't make fans quieter by themselves; they let you run them at quieter speeds.

How do ARGB controllers work?

An ARGB controller connects multiple addressable fans or strips and drives their lighting together, which is useful when your motherboard lacks enough ARGB headers. Some are controlled by software, others by a physical button or remote. Match the controller to your fans' addressable standard so the lighting syncs correctly.

Are fan accessories covered by warranty in South Africa?

Fan controllers, hubs and cables bought from Evetech carry local warranty, so you're supported by a South African retailer. Terms vary by product, so check the specific page. Buying locally also means faster delivery and easier support than ordering small accessories from overseas.

Fan Controllers, Hubs & Accessories 🔌

Fan accessories give you control over how your PC cools and how tidy it looks inside. A fan controller or PWM hub lets you run several fans from one header and set their speeds — quiet at idle, ramping up under load — while splitters and extension cables route everything cleanly. ARGB controllers add or expand addressable lighting when your motherboard runs out of headers.

If your build has more fans than fan headers, a hub is the simplest fix: it powers and controls a stack of fans from a single PWM header so the motherboard still manages their speed. Add a controller when you want manual speed control or a built-in display, and use splitters or extensions to reach awkward mounting points without messy cabling.

Evetech stocks fan controllers, PWM and ARGB hubs, splitters and extension cables, all with local warranty and nationwide delivery. Browse the range below and match the accessory to your fan count, your headers and the look you're after.

How to Choose Fan Accessories

The right accessory depends on what you're trying to fix: not enough fan headers, fans you can't control, messy cabling, or lighting you want to sync. Knowing the difference between a hub, a controller and a splitter saves you buying the wrong thing. The points below sort it out.

A fan hub powers several fans from one motherboard header and lets the board keep controlling their speed automatically — ideal when you've run out of headers. A fan controller gives you manual control, often with a dial, buttons or a display, to set speeds yourself independent of the motherboard. Pick a hub for "more headers, automatic control"; a controller for "hands-on control".

PWM hubs and controllers vary 4-pin fans precisely, letting them idle near-silent and ramp under load. DC control adjusts 3-pin fans by voltage and is coarser. Match the accessory to your fans: a PWM hub fed by a PWM header passes that fine control to all the fans plugged into it. Mixing types works but you lose precise control on the DC fans.

A splitter runs two or three fans off one header — handy for a couple of extra fans without a full hub, though watch the header's power limit if you chain many. Extension cables let a fan reach a header on the far side of the case for cleaner routing. Both are cheap fixes for a tidy build; a hub is better once you're running four or more fans.

If your motherboard is short on ARGB headers, or has none, an ARGB controller or hub lets you connect and sync addressable fans and strips together. Some are controlled by software, others by a button or remote. Check that the controller matches your fans' addressable standard and, where relevant, your motherboard's lighting software so everything syncs as one.

Accessories aren't just about control — a hub mounted behind the motherboard tray collapses a tangle of fan cables into one neat run, and extensions let you route cleanly rather than stretching wires across the board. A cleaner cable layout also keeps airflow paths clear. Plan where the hub mounts and how cables route before you wire everything in.
