You finally did it. You bought the Lian Li Strimer Plus V2 cables, spent an hour wrestling with cable management in the back of your O11 Dynamic, and flipped the switch. They glow. It’s glorious. But then you open your desktop and realize that getting those neon pipelines to actually do what you want is a whole different beast. Honestly, figuring out how to control strimer cables in l connect should be intuitive, but Lian Li’s software has enough quirks to make even a seasoned builder want to pull their hair out.
L-Connect 3 is powerful. It’s also picky. If you don't have the controller toggled correctly or the firmware updated, you're stuck with the default rainbow puke. We've all been there.
The Controller is Everything
Everything starts with that little black box tucked in your cable basement. If you’re using the Strimer Plus V2, you need the dedicated controller that came with the 24-pin motherboard cable. You can't just plug these into a generic ARGB header and expect L-Connect to see them. It won't.
First thing’s first: check the side of the controller. There is a tiny physical switch. If you have the original Strimer Plus (not the V2), that switch matters immensely for signal routing. For V2 users, it’s more about the USB header connection. You need a direct line to your motherboard's USB 2.0 header. Splitters are the enemy here. I’ve seen dozens of builds where the Strimers flicker or vanish from the software because a cheap 1-to-2 USB internal hub couldn't handle the data bandwidth.
Plug it in directly. Seriously.
Getting L-Connect 3 to Actually Talk to Your Cables
Once you’ve verified the hardware, fire up L-Connect 3. If the "Strimer Plus" tab doesn't show up on the left-hand sidebar, the software doesn't know the controller exists. This usually happens for two reasons: a missing driver or a power issue.
Lian Li uses a specific bridge chip in their controllers. Sometimes Windows just sees it as an "Unknown Device." You'll want to head to the Lian Li official website and grab the manual firmware update tool. It’s a tiny .exe that forces the controller to wake up. Run it, unplug the USB, plug it back in, and usually, the tab appears like magic.
Once you’re in the Strimer Plus menu, you’ll see a layout of your cables. Usually, it's a 24-pin and either an 8-pin or the newer 12VHPWR Triple 8-pin.
Customizing the Light Show
This is where it gets fun. Most people think you just click a color and go. Nope. The V2 cables have individual light zones—sometimes up to 120 LEDs on the 24-pin.
In the software, you can choose between "All" or individual "Strip" control. If you want that deep customization where colors chase each other across different strands, you have to select the specific cable icon. There’s a "Quick Settings" bar at the top for basic stuff, but the real meat is in the individual effect list.
- Dazzling: This is the signature Lian Li look. It makes the light look like it’s flowing through a liquid pipe.
- Meteor: Great for high-contrast builds.
- Static: For the minimalists who just want a solid white or "vaporwave" pink.
One thing to watch out for is the brightness slider. The V2 Strimers are bright. Like, "blind you in a dark room" bright. Running them at 100% all the time actually generates a decent amount of heat and can, over years, lead to LED degradation. Drop it to 75%. It looks better anyway; the colors don't look as washed out.
The Motherboard Sync Trap
A lot of people ask how to control strimer cables in l connect while also using their motherboard software like ASUS Aura Sync or MSI Mystic Light.
There is a toggle in the top right of the L-Connect 3 Strimer page that says "MB Lighting Sync."
Turn it on, and L-Connect steps aside. Your motherboard software takes over. But here is the catch: motherboard software is usually terrible at handling the high LED count of Strimers. You’ll get "blocky" transitions. If you want those smooth, buttery animations, keep MB Sync OFF and do your tweaking directly in L-Connect.

If you absolutely must sync everything, make sure you've connected the ARGB 3-pin cable from the Lian Li controller to a 5V header on your board. If that cable isn't plugged in, the toggle does nothing.
Troubleshooting the "Ghost" Cables
Sometimes, L-Connect shows the 24-pin but the GPU cable is dark. Or vice versa.
This usually comes down to the number of LEDs the software thinks is attached. In the settings menu of L-Connect 3, there’s a section for "Device." You can manually tell the software which version of the cable you have. If you have the 12+4 pin (12VHPWR) but the software thinks it’s an old Triple 8-pin, the lighting mapping will be completely broken. It’ll look like a glitched Nintendo game.
Check your cable version. Match it in the settings. Save. Reboot.
Why Does My Lighting Reset?
It’s annoying. You spend twenty minutes perfecting a dual-tone teal and purple gradient, you restart your PC, and it’s back to rainbow.
This is almost always a background process conflict. If you have Corsair iCUE, NZXT CAM, and L-Connect 3 all running at once, they fight for control of the SMBus. It’s a mess. To fix this, you need to go into your Startup Apps and disable anything you don't strictly need.
Also, make sure L-Connect 3 is set to "Start on Boot." If the service doesn't start, the controller reverts to its hardware default (rainbow).
Actionable Next Steps for a Perfect Setup
If you want the cleanest control over your Strimers, follow this sequence:
- Direct Power: Ensure the controller is powered by a dedicated SATA cable from your PSU. Don't daisy chain it with four hard drives. LED strips draw more current than you'd think.
- Firmware First: Before getting fancy with colors, download the Lian Li firmware update tool. Version mismatches between the controller and L-Connect 3 are the #1 cause of "device not found" errors.
- Clean the Software: If L-Connect is being buggy, don't just reinstall it. Use a tool like Revo Uninstaller to wipe the registry keys. Lian Li's uninstaller leaves behind old config files that can corrupt new installations.
- Define Your Zones: Spend five minutes in the "Individual" tab rather than the "Quick Settings." Setting different speeds for the inner and outer strands of the Strimer creates a 3D effect that looks significantly more "high-end" than the presets.
- Check Your USB: If your motherboard is short on headers, use a powered internal USB hub (like the one from NZXT). Passive splitters often fail to provide enough voltage to keep the controller stable during heavy gaming loads.
By focusing on the hardware handshake first and the software aesthetics second, you avoid the flickering and detection issues that plague most builds. Your Strimers should be the highlight of your desk, not a source of troubleshooting frustration. Keep the brightness sensible, the firmware current, and the USB connection direct.
