Question How do I fix my Async A-RGB lighting ?

So I just built my new PC and am using an Arctic Liquid Freezer 360 ARGB. The fans and RGB controls are all connected through the daisy chain link on my motherboard.

The problem is (see photo below) that the timing for the RGB lighting of my fans on the AIO is off. I can change colours etc without any problem but I can't sync the lights, thus making them look off.

Relevant components:
3 x Arctic 140mm aRGB Fans
MSI B850 Gaming Plus WiFi motherboard

Note: I am using the J-ARGB V2_1 slot header to connect the fans on my PC.

Edit: I tried changing the header and I already have installed MSI Mystic light that sadly didnt change anything.

3x Arctic 140mm argb Fans
These;

Did you download and install MSI's Center then MSI's Mystic Light widget/add-on? If not, get that and you should be able to manage the lighting on your system.

Your motherboard has 3x ARGB headers, have you tried using other headers?

I already have MSI Mystic installed and that unfortunately changed nothing.

Changing the ports also didnt help. Going to add that into my edit.
 
Two thoughts for you to check.
1. Arctic provides their own software tool (SignalRGB) for configuring the lights in that system. But you also have the MSI Mystic Light software tool which I believe is better to use with that mobo. IF you actually have BOTH of those installed and operating, they might be clashing. Check and ensure that SignalRGB is NOT installed.

2. There now are two versions of ARGB lights: the Original (some call it V1), and the newer V2. These are different enough that you cannot mix them on one lighting circuit. But also, the Controller that runs your lights must be set to send the correct signal type to those lights. The three MSI mobo headers JARGB_V2_n all are capable of working with either type of lights and usually are set by default to the new V2 version. I believe the lights in the Arctic system also are this new type, so that all should work, and you DO have the lights working. BUT one of the special features of this newer system is that the lights in separate units (like three fans on the rad) CAN be treated as different sections of an overall system so that the lighting patterns you choose can be sequences of lights extending over the entire set and NOT all of them the same pattern (synchronized). For example, a moving rainbow can "flow" through all the three fans as if they were one long fan light strip, instead of flowing through each fan identically. So look in MSI Mytstic light for a setting to synchronize or NOT to synchronize.

Ok you were right about my motherboard seeing everything as one whole lightstrip. I tried that theory out by addressing each light individually ( I just realized that Mystic Light also shows more individual lights for the daisy chain fans compared to the single connected fan). Now I get to the next problem. Mystic Light is able to detect if it is a V1 or V2 light. So its using by default the V2 as you pointed out with the Arctic fans, but I was sadly not able to seperate through Mystic Light. I am not sure if I need the pro version of Signal RGB to add the seperate them as I cant do that with the free version.

If you look on the back of the radiator fan assembly do you see a series of plugs where the fans are connected together? If yes, if you pull the plugs apart are they 3 pin argb plugs and sockets? To address the fan's argb's separately you will most likely have to connect each fan via an extension cable to a separate argb port on your motherboard. Then software like SignalRGB can be set to see them as separate devices which you can program to match.
 
You have confirmed that this is a V2 version of the ARGB lights in the fan frames AND the pump motor head. My understanding of the V2 version of ARGB is that (compared to V1) it changes the way the Controller deals with several light strips connected to the SAME ARGB output port. In your system you can do this by using the duplicate connectors on each lighting header to make a "daisy chain" connection of all lights to ONE lighting header. (This does not use a lighting Splitter.) So I encourage you to look very closely inside the MSI Mystic Light tool for the many options to control the lights.

It should have separate screens for each mobo JARGB_V2 header, although it MAY show you only the headers you actually ARE using. At that level of selecting which header you are configuring there should be a choice of whether each header is handled separately, or whether all headers are to be synchronized to one pattern (from one configuration screen). THEN once you select a particular header and it shows you how many lights are present, there should be an item to choose whether all of the individual strings are lights are to be treated as one continuous string or as several (up to 4) different strings that all need to be synchronized to the SAME display pattern.) If you can tell it to treat as separate strings, that will get you the "synchronization" of three fans' displays (plus the pump top) on one JARGB_V2 header. Basically, this mode does not use that special feature of V2 and works like a V1 display would do.

If that does NOT work for you, then dwd999 has a really good idea, but it does not require SignalRGB. I think. If I understand the V2 system, that special feature is NOT applied when the light strings all are on DIFFERENT controller output ports - in your case, on different mobo JARGB_V2 headers. So if you connect the three rad fans to the three separate ports (do not use the daisy chain connection system), then in MSI Mystic Light you should see three output ports to configure, and inside each you should find the right number of LED's for ONE fan light string. So before going into configuring any of those three ports, look for how to synchronize ALL ports to one display pattern. That should get you only ONE way to configure since it will apply to all ports. Unfortunately, though, that leaves the pump lights not connected to any JARGB_V2 port. You could connect it to one of the fan lighting cables, but then that pump top and one fan would give you the same issue you started out with. That's why I suggest above that you try first to find a way to set up ONE port so it treats all four lighting units as separate units rather than as one joined-up string.
