MSI Mystic Light won't detect/change the color of the RING LED (AMD Wraith Prism CPU Cooler)

Hello all,

Recently, I asked a IT shop to built a PC for me with MSI B450 Tomahawk and Ryzen 7 2700X with AMD very own stock cooler and other components. I installed all the necessary drivers/updates. I went to install the MSI Mystic Light utility from the MSI B450 Tomahawk motherboard website itself.

After I have installed, used the Mystic Light and tried to change the colors to static animation with purple color, the LED from the RING of CPU Cooler doesn't affect or change. It still stucks in a rainbow animation setting and it won't go away. I tried to restart the program and change or reinstalled the utility, it doesn't work. Anyone have any ideas on how to tackle this?

Thanks!

/Vinnie

For controlling the CPU cooler LEDs, there are 2x options:
1. USB 2.0 cable from CPU cooler to MoBo (controlled by Cooler Master software, LINK).
2. RGB cable from CPU cooler to MoBo RGB header (controlled by MSI Mystic Light software).

Install the Cooler Master software and look if you can control your CPU cooler LEDs. If you can, your CPU cooler is wired according to the 1st method. For your need, you'll need the wiring be as 2nd method is. You just need to unplug the USB 2.0 cable from MoBo and connect the RGB cable to your MoBo header.
If you don't have that RGB cable, call your IT shop since Wraith Prism cooler comes with both cables and they might have kept the excess cables for themselves (it has happened to me once and due to that i won't let anybody else to build a PC for me anymore).

Hello! Thanks for your solution! I have plugged in the USB 2.0 cable from CPU cooler to MoBo, unplugged the RGB cable, use the Cooler Master software with MSI Mystic Light and it worked.

I will recommend my friends who are using the Prism Cooler to use USB 2.0 Cable. Thanks for your help sir!

I am digging this thread up as I am facing the same problem.
My Ryzen 2700 fan comes with 2 connectors, one for the fan and one RGB, I plugged both, the red ring lights up but it's not detected by MSI Mystic Light nor cooler Master app

Your MoBo is what?

Also, have you tried connecting only USB cable, without connecting cable to MoBo RGB header?

My mobo is a MSI B450M Gaming Plus
The CPU fan came with a traditional cable coming out from it and a second cable which has to be plugged in the fan, the 1st one I plugged into the mobo cpu fan socket and the second cable into the JRGB2 (it's closer to the cpu than JRBG1)

Your MoBo does not support MSI Mystic Light and you can't use that software to control your CPU cooler LED. Instead, you need to use MSI Gaming App software since that software controls the JRGB2 and JRGB2 headers on your MoBo.

Also, as i said above, AMD Wraith Prism CPU cooler comes with 2x cables for it's RGB,

So, if you want to use Cooler Master software to control the LED, you will need to connect the USB cable from CPU cooler to your MoBo.

The B450M Gaming plus has mystic light, I am already using it for the mobo colors and Geforce.
Also it's listed when picking Do you prefer to have onboard Mystic Light Extension(4-pin / 12V) header?

I have the 2700 without x, the fan is different

Here are your MoBo official specs,
link: https://www.msi.com/Motherboard/B450M-GAMING-PLUS

On that page, care to point out where it is stated that your MoBo has MSI Mystic Light feature and/or your MoBo does support MSI Mystic Light?

Even your MoBo manual doesn't say your MoBo supports MSI Mystic Light. On page 16, there is only stated:
JRGB1, JRGB2: RGB LED Connectors
The JRGB1/JRGB2 connector allows you to connect the 5050 RGB LED strips 12V.

* Please use MSI’s software to control the extended LED strip.
Only single reference about Mystic Light in your MoBo manual is at the included software section, where Mystic Light software is included with the MoBo DVD. Also, your MSI B450M Gaming Plus MoBo doesn't have RGB LEDs on it, where you could use MSI Mystic Light software for "MoBo colors".

What your MoBo has, is standard 4-pin RGB header (two of them) and why MSI calls those as:"Mystic Light Extension" on the Mystic Light page, that i do not know. Like i said above, you'll need MSI Gaming App to control your MoBo RGB headers.

Silly me!
No mystic leds on the bard but...to control the led colors and pulses of the cpu fan I have to choose Mobo in mystic light! Go figures why it's not CPU. So the 2 leds I saw on the mobo map in the app were the JRGB sockets and which colors + pulse mode they will give to any compatible device.
So yes I can now change the ring of the cpu fan to anything I want, it looks really cool, I will buy an Aerocool rgb fan 120mm for my case to complete the coolness

Glad to hear that you got your issue resolved.

If you want to see something truly cool, look towards my Skylake build,

Thanks
I received an RGB fan 120mm for my case today, I will plug it to JRBG2 socket and try mystic light with it.
My case is nice but it could be more ''alive'' if I add this useful fan

I have the wraith prism cooler that came with my 2700x and a MSI x470 Gaming Pro carbon mobo. Your saying to be able to control the outer ring color I need to unhook the rgb cable? I currently have the usb and rgb hooked up. On the AMD website it says> If you have one of these pre-installed Wraith Max coolers that use USB-based RGB control, you can download the RGB illumination control utility for AMD Wraith Max cooler from CoolerMaster . This utility will *not* work on boxed Wraith Max coolers purchased at retail, which require motherboard software support for RGB control.

Like i said in my 1st reply, there are 2x methods to control Wraith Max or Wraith Prism LEDs:
1) USB 2.0 cable from CPU cooler to MoBo (controlled by Cooler Master software, (LINK).

2) RGB cable from CPU cooler to MoBo RGB header (controlled by MSI Mystic Light software).

Use only one of them, not both of them at the same time.

I read that in the first post but I was asking if the mobo can control the outer ring. I asked MSI and they said it does not and that you will need the coolermaster software. Guess I will be running the usb instead of the rgb.

I have just the usb connected now and downloaded the coolermaster software. It was working but every time I restart it looses the settings.

Can't help you with that one since i don't have in-depth knowledge about Cooler Master RGB software. Contact Cooler Master about this.

I made an account just to post this so I apologize if this breaks any rules or anything. Writing here with a solution that worked for me to be able to use both mystic light and the wraith cooler master software. For me either my gpu or wraith cooler would default to their base colors on restart or boot.

Solution:
In dragon center change your gpu color to what you'd like and turn on the "Mystic Light will overwrite third party RGB software after system restart".

In the cooler master wraith software set your colors and export the profile and save it to your desktop (this may not be necessary but good to have).

Make a text file and put the following in it:

---------- Start of text file (do not put this line in it) ------------
if not DEFINED IS_MINIMIZED set IS_MINIMIZED=1 && start "" /min "%~dpnx0" %* && exit
@Echo off
timeout /T 3 /nobreak >nul
cd "C:\Program Files (x86)\AMD Wraith\Wraith Prism"
Start "" "Wraith Prism.exe"
timeout /T 5 /nobreak >nul
taskkill /IM "Wraith Prism.exe"
exit

---------- end of text file (do not put this line in it) ------------

Now rename that text file to a .bat file (e.g. Cooler Colors.bat)

In your computers search bar type %appdata% and enter

Navigate through these folders Microsoft>Windows>Start Menu>Programs>Startup

Right click > New > Shortcut > (find your .bat file you just made) > Next > Finish

That should be it. The colors may start out wrong for about 10-20 seconds on startup (maybe longer if you have a slow computer) but should then be fixed.

Bat file explanation:
Line 1: opens the cmd prompt in minimized mode so it doesn't site on your desktop for 10 seconds. It could be removed if you really want.
Line 2: Essentially turns off the cmd output. Could be removed you if really want.
Line 3: This is just a timer to let dragon center change the colors on startup (dragon center doesn't need to be opened on startup, just that setting mentioned earlier needs to be on)
Line 4&5: Runs the Cooler master Wraith software. If you have the software located somewhere else change line 4 to the location.
Line 6: Gives time for the Cooler master Wraither software to open.
Line 7: Closes the Cooler master software to set the cooler color.
Line 8: exits the bat file.
The reason this works is because when you close the cooler master software it sets the wraiths colors to what is set. Kind of an oversight by them but in this case is a welcomed one.
