hello guys, im planning on buying 6rgb fans (DF 12025 - id cooling > http://www.idcooling.com/Product/detail/id/127/name/DF-12025-RGB-TRIO if you need reference about the fans)
and im using B450m mortar. I'm trying to picture how im going to connect them before buying and according to the instruction on the website of the fan manufacturer it says to connect to RGB header and on the pictures it looks like its a
12V RGB connection on the motherboard and on my MOBO I have 2 JRGB that says 12v rgb (4pins) >> is that the same??
sorry im just new to setting up fans and rgb's

Thanks!!!

OK, this will be pretty straightforward. Those fans come in sets of three with associated cables and adapters. Each set includes a LED Controller box and a hand-held remote control. You can choose to control the lighting effects EITHER using the included controller and remote control, OR using the mobo RGB header and its software, but not both. Since you are interested in mobo-based software control, I'll concentrate on that. Connections and control of the fan motors are done separately, so we'll get to them later.

With six fans from two sets, I suggest you connect one set of three together, and then the other set very similarly to another mobo header. Your mobo has two of the correct header types (plain RGB with 4 pins and a 12 VDC supply line) called JRGB1 and JRGB2 on the bottom edge - see manual p. 36. The fan sets come with a one-to-four RGB Splitter (and a small adapter you will not need). You do not need the LED Controller box or the remote control with the fan set. Plug the RGB lighting cables from each of three fans into the output arms of the RGB Splitter (leaving one unused). Plug the single input connector of that Splitter into one of the mobo RGB headers. In each case, note that the connectors have marks on them for the +12 VDC pin, and they MUST match up at each joint point. Now go on to the other set of three fans, and make exactly the same connections to the other mobo RGB header. When your system is working, go to the MSI website and download their Mystic Light software tool, load it and use it to control the RGB lighting effects of all the fans.

Now to fan motor connections. Each has a female fan connector with 4 holes on the end of its fan motor cable. See mobo manual p. 33. The mobo has one CPU_FAN header that you must use for the cooler system on your CPU. Then it has three SYS_FAN headers, but you have six fans. You can group them together as three fans each on two of those headers if you get two simple three-output Splitters like this

Note that these are Splitters with only two types of "arms". One arm ends in a female connector to plug into a mobo SYS_FAN header; three output arms each end in a male connector to plug in a fan. Do not get a HUB, which is a different device that also has a third type of arm that must plug into a SATA power output from the PSU.

As a minor alternative if it suits you better, you can get three two-output Splitters like this

and make three groups of two fans each on your mobo's three SYS_FAN headers.

According to the mobo manual (p. 33), the three SYS_FAN headers are configured by default to use what is called DC Mode required for 3-pin fans. But your fans are of the newer 4-pin design, so you should use the configuration options in BIOS Setup's Hardware Monitor screens to change that to PWM Mode, then Save and Exit.
