ARGB/RGB fans with no motherboard header

Hi,

So I've ordered a Cooler Master H500M case which comes with 2 front ARGB fans and an ARGB controller. The 2 fans connect via 1 splitter cable to one of the ARGB headers on the controller. The controller has a second header for additional ARGB components. It connects to the front panel reset switch, to allow quick external modifications to the lighting pattern, and it also connects to USB 2 on the motherboard. It has the option to connect to a motherboard ARGB header, but I believe this is optional, and used to allow the motherboard software to manage lighting instead of the reset switch.

Controller layout: https://ibb.co/i7a1Fp

My motherboard doesn't have any RGB or ARGB headers and I'm not looking to upgrade at the moment. I know that RGB use 4 pin connections and ARGB use 3 pin connections so what I'd like to know is...
1. Can I use an RGB fan on this controller, as it looks to have 4 pins on it? (Or rather can any RGB fan work with an ARGB header?)
2. Can anyone confirm that I DON'T need an ARGB header on my motherboard for this controller to work? (The point of the controller is to add ARGB functionality without needing a header, right?)

Also, can anyone suggest some good, quiet RGB/ARGB 120mm fans (preferably ARGB) with high static pressure to be used on a radiator. I'll be after 3. I was going to get the 'EK-Vardar EVO 120ER RGB' with the rest of my water cooling loop parts, but heard they were unreliable. The 'Cooler Master MF120R' is a little cheaper and comes in a 3 pack with it's own controller, but it has lower static pressure and newegg reviews indicate that it's hit-or-miss on whether you'll get one of poor quality or not. As my WC loop is overkill, I was hoping to run the fans on a low speed also, but I read that due to PWM power, the MF120R fans aren't as bright if running lower than 100% speed.

I was also looking at the ML120 Pro RGB, which comes in a 3 pack with the Lightning Node Pro and an RGB hub. These have the lowest static pressure, but allow me to control the lights separately from the front fans on the reset switch, which I like but isn't crucial. Some reviews I've read seem to indicate some decent noise to airflow/pressure figures.

Any recommendations on the above listed fans? Any other ones you might recommend instead?

Thanks

I believe you will have to use ARGB fans, not the plain RGB fans. The two designs have different ways to control the LED's in them. The simpler RGB lights (and fans) have three LED colours, and they use one lead for the Ground side of each colour, plus a common +VDC power supply lead. The mobo header simply controls whether or not each LED colour is connected to Ground or not. The ARGB system is different. It does use three LED colours with a +VDC power supply, a Ground, and a Control Signal line on three wires. The light unit itself includes a controller chip that receives the Control Signal from the mobo header and then does the control of the LED's. Your ARGB controller uses this latter system and depends on being used with ARGB...

Thanks. I pulled the trigger and bought the ML120 Pro RGB which come with their own RGB hub and controller. Simply needs USB power and I can have the lighting separate from the front fans. Reviews have been decent for Rad usage also.
