2 diffrent 4pins thing

Pclol · April 3, 2020

I recently purchased Deepcool MATREXX 55 V3 Midi Tower. And after that I purchased Cooler Master MasterFan SF120R ARGB. Both the fan and the matrexx was 4pin + the fan was also 3pin. But nothing worked together some one help? cable transition Or something?

Those with round pins and holes are for RGB.

The connector in the center is regular fan header (probably used to take power for the water pump and maybe report fan rpm to motherboard)

Top left is a female A-RGB connector (12v). Middle is a simarilar cable for RGB I think. (4 pin), right is a female version of of what is on the left.

For the bottom photo. Left is D-RGB (5v addressable), middle is a 4 pin PWM cable (makes the fan go whooosh). Right is a male D-RGB (5v addressable) connector.

For D-RGB you have your motherboard to support it. That or get a controller for it. 12v addressable A-RGB is more common the D-RGB.

So looking at case specs, you have bit of issue here. First of all, you should always research parts before buying anything. While PC building side of things is easy, it requires research to learn what parts work together.

Case has 4pin 12V RGB. You've bought 3pin 5V ARGB fans to go with it. These two are NOT compatible directly with eachother. They can't use same connectors. The question becomes, did you want to sync everything and what is your motherboard? I think there might be some mobo's which support both 5V ARGB and 12V RGB at the same time, but I'm not 100% about it.
