5 notos 120 pwm fans 2 are partially lit up and stuck on blue, and the other 3 have between 3 and 5 individual LEDs lit up.

Question

building a gaming PC with an MSI Z390-A PRO motherboard

I have also installed 5 notos o120 pwm fans Power for the fans is hooked directly to the 5 sys fan slots on the motherboard, and they are all linked to the touchaqua control board that is powered by the SATA cable

when I first installed the fans, they worked, and cycled through colors when I tested them.

Then I hooked up the hard drive, and had some issues with it, finally troubleshooting and discovering I had a bad drive. I replaced the drive, which was immediately detected, but then the lights on the fans just quit doing anything. 2 are partially lit up and stuck on blue, and the other 3 have between 3 and 5 individual LEDs lit up. They do not cycle colors like they did before.

I have replaced the touchaqua control board, and have all 5 of the fans powered by the motherboard.

I have read the instructions, but they are not terribly clear, and there is no trouble shooting instructions

I have tinkered in the bios settings and turned on PWM on each of the fans. I installed MSI's Mystic Light software and it works for the LEDs on the CPU fan and on the RAM chips, but still, just a few sickly blue lights on the case fans.

Is it possible to burn the LEDs out in the fans?

Am I missing something?

Do I need to adjust something?

any help would be appreciated.

Hello Tony,

It seems that the LED controller of the fan is not compatible with your motherboard.
There are two ways to solve this problem.
Only use the LED controller to control the DRGB of the fans.
Or please do not use the LED controller, but only connect all the LED of the fans together and connect it directly to your motherboard, which is 5v, 3 pin slot.
And then control the LED by the software of your motherboard.
Please have a try, any question, feel free to contact us.
