To daisy chain AC Infinity fans, you simply connect multiple fans to a single controller using the included 4-pin cable.
This lets you manage airflow across your grow tent with one convenient control system.
Daisy chaining AC Infinity fans is one of the easiest ways to expand your ventilation setup without adding extra controllers.
In this post, we’ll walk through exactly how to daisy chain AC Infinity fans, what cables you need, and common mistakes to avoid.
Let’s get into it.
How to Daisy Chain AC Infinity Fans: The Basics
Daisy chaining AC Infinity fans is straightforward once you know the right ports and cables.
The process works across most AC Infinity models that use the smart controller system.
Here’s what you need to understand before you start connecting fans.
1. Check Your Fan Models for Compatibility
First, confirm that each fan has a 4-pin communication port.
Most AC Infinity fans like the Cloudline T6, T8, and S6 include this port.
If you’re newer to AC Infinity, the port is usually located near the power cord.
Make sure all fans are from the same series so the controller recognizes them properly.
You can daisy chain AC Infinity fans from different series sometimes, but it’s safer to stick with matching models.
2. Use the Included 4-Pin Interconnect Cable
Every AC Infinity fan kit comes with a 4-pin interconnect cable.
This cable is specifically designed for daisy chaining AC Infinity fans together.
Look for the port labeled “4-pin” or “PROBE/FAN” on the back of the fan.
Plug one end of the cable into the first fan’s port.
Then plug the other end into the second fan’s port.
Repeat this for any additional fans you want to chain.
3. Connect the First Fan to Your Controller
After linking the fans together, connect the first fan to your AC Infinity controller.
The controller is the brain that reads temperatures and adjusts speeds.
Plug the controller’s cable into the first fan’s control port.
Once connected, the controller will recognize all fans in the chain.
Now you can set one speed and every linked fan will follow.
Why Daisy Chain AC Infinity Fans in Your Grow Setup?
There are several solid reasons to daisy chain AC Infinity fans instead of using multiple controllers.
This strategy simplifies your setup and improves consistency.
1. Single Point of Control
Daisy chaining AC Infinity fans means you adjust everything from one screen.
This is super useful in a grow tent where you might have intake, exhaust, and circulation fans.
You don’t need to walk around changing settings on separate controllers.
It’s all centralized, which saves time during daily maintenance.
2. Better Temperature and Humidity Matching
When you daisy chain AC Infinity fans, they all operate at the same speed.
This creates a balanced airflow pattern where intake and exhaust work together.
For example, if your exhaust fan runs at 60% because temps are high, your intake fan matches that speed.
This keeps your tent’s environment stable and reduces hot spots.
3. Cleaner Cable Management
Having one controller means fewer cables running out of your tent.
Daisy chaining AC Infinity fans reduces clutter and keeps your space tidy.
You’ll have one main cable to the controller instead of several separate ones.
It’s a small win, but anyone with a crowded grow room knows how valuable that is.
Step-by-Step Guide: How to Daisy Chain AC Infinity Fans
Let’s walk through the process in a simple, hands-on way.
Follow these steps and you’ll have your fans linked in under five minutes.
Step 1: Power Off All Devices
Before you daisy chain AC Infinity fans, shut off power to the fans and controller.
This prevents any electrical hiccups while you’re plugging cables in.
Unplug the power adapters from the wall.
It’s a small safety step that makes the whole process smoother.
Step 2: Locate the 4-Pin Ports
On the controller end, find the port labeled “FAN” or “4-PIN.”
On each fan, the port is typically on the rear housing near the cord.
If you’re unsure, check your manual or the AC Infinity website.
You’re looking for a small rectangular socket that matches the interconnect cable.
Step 3: Link the Fans Together
Take your interconnect cable and connect the first fan to the second fan.
If you have a third fan, connect the second fan to the third, and so on.
You’re creating a literal chain, one fan linked to the next.
Make sure the cables click in securely so they don’t fall out.
Step 4: Attach the Controller to the First Fan
Now connect your controller’s cable to the first fan in the chain.
This is the fan that will receive commands and pass them down the line.
Plug it into the same type of port you used for the interconnect cables.
Verify that everything is snug before powering on.
Step 5: Power On and Test
Plug your fans back into the wall and turn on the controller.
The controller should automatically detect all fans in the chain.
Try adjusting the speed from the controller and watch all fans respond.
If only one fan works, double-check your cable connections.
Common Mistakes When You Daisy Chain AC Infinity Fans
Even though the process is simple, there are a few pitfalls to avoid.
Knowing these will save you from frustration.
1. Using the Wrong Port
Some AC Infinity fans have multiple ports like sensor ports and control ports.
Don’t plug the interconnect cable into a sensor port unless instructed.
Daisy chaining AC Infinity fans requires the dedicated fan control port.
Check the label beside each port if you’re unsure.
2. Exceeding the Maximum Chain Length
You can’t daisy chain AC Infinity fans forever.
Each controller has a limit on how many fans it can handle.
Usually, you can connect up to 8 fans on a single controller.
Check your specific model’s manual for the exact number.
Going beyond that can cause signal issues and inconsistent speeds.
3. Forgetting to Update Firmware
If your controller has the option, update its firmware before chaining fans.
Older firmware might not support multiple fans properly.
You can usually update through the AC Infinity app.
It’s an easy step that ensures smooth communication between devices.
So, Can You Daisy Chain AC Infinity Fans Easily?
Yes, you can daisy chain AC Infinity fans easily with the right cables and a few minutes of time.
The process relies on the 4-pin interconnect cable that comes with your fans.
Just link each fan’s port to the next and connect the first fan to your controller.
Once it’s set up, you’ll have synchronized airflow with single-point control.
Daisy chaining AC Infinity fans is one of the most efficient ways to manage your ventilation setup.
This post covered the basics, benefits, step-by-step instructions, and common mistakes when you daisy chain AC Infinity fans.
Now you can go ahead and link those fans for a cleaner, more effective grow environment.
