Cabinet RGB help

[Grudge69]

I have a deepcool 55 matrexx mesh and b450 tomahawk max which has 3 pin connector and my fans have 2 pin cable so I used a converter. But now whenever I use any RGB effect like breathing a voltage fluctuation occurs where the RGB turns off stopping the fans too and then it starts again. I have to put the effect on static only which sucks so please someone give a solution. I also have a liquid cooler so I want all my fans to sync with motherboard

2 pins fans should not use power from the motherboard.

You should plug it with a molex to 3 pins adapter so it will draw power from the PSU.

I did use an adapter and then the problem occurred

as far as i know, the 4th pin is for the adressability of those fans. Therefore, converting them from 4 to 3 makes you loose this one lane that gives you the possiblity to change the RGB mode and color while trying to force the information of the 4th lane somewhere between/in one of those 3 left.
Obviously, if you then try to change it, shit like this happens.

But i might be wrong.

What kind of a converter? 3-pin and 4-pin RGB connectors are completely incompatible. One is 5V, data, and ground; the other is +12V+pwm (x3) and ground. You'd need something with processing power in it to convert one signal to another

can you suggest any converter for that?

Well.. buy compatible components in the first place. 
if your case comes with stock RGB fans, it usually comes with a dedicated RGB header. Just use that. 
You wont be able to sync all of your RBG products with one click, but with 2 or 3. And if you dont want to change your color ever 30 minutes, you should be fine.
