Can I Connect Multiple Fans To One Header

To keep the headers safe and last longer and keep my mobo from frying.
Can i connect multiple fans to one header. So i am assembling my pc for the first time and came in a bit of a glitch. Hello my motherboard has 1 rbg header. I read a few threads and i understood that i can connect two fans to one. So the motherboard asus b85m gamer i chose has only one fan header.
The only problem is that the motherboard i have only had one argb header. My case supports 4 120 mm fans. Check the manual to see what current the fan header can give and compare it to the watt rating of the fans watts 12v amps. In fact there are a number of ways to do so.
I ve been scouring the internet for an answer and could only find answers for standard rgb. I am buying 5 new case fans 3 masterfan pro 120 air flow and 2 masterfan pro 120 air pressure fans. Some high end boards will have one or mor 2a headers. Could i connect two 3 pin fans to the 3 pin header and two more to the 4 pin header.
Use 83 of header rating to account for inrush current 1500 rpm fans. Is it possible to connect multiple argb to a single header with a splitter or something. So again using that typical 140mm 1250 rpm fan 0 14 amps. I should mention i am planning on using a fan hub to connect all the fans to power and run them with pwm control.
Such a splitter connects two. As far as splicing power and gnd together as long as the current draw of the 2 combined isnt more than the mobo can handle you will be fine. However if they are identical fans monitoring one should reflect 2. From my understanding i can actually buy 3 pin fans they seem to be cheaper and use a splitter to connect them all to the 4 pin header on the motherboard.
1250 rpm fans. Im trying to decide between fans ones with rgb the others with argb. Cooler master states that the fans are compatible with my motherboard without an rbg controller but how do i connect them all. Also my mobo only has one 4 pin cpu fan header one 4 pin system fan header and one 3 pin system fan header.
I have a gigabyte ga b250m ds3h which has only 1 system fan header 4 pin and of course 1 cpu fan header. Use 75 of header rating to account for inrush current. First if you know the power ratings of your fans and of your motherboard you may be able to use a splitter such as the rosewill case fan pwm cable splitter.
