Help connecting fans to mobo

[jpdelabar]

I have a gigabyte b450m which from what I can tell only has two fan ports. I plugged the CPU fan into the CPU fan port and then I only have one other port which is labeled sys fan 1 and no others (unless I am mistaken)
So can I plug a splitter into that sys fan port too add 2 or 3 fans?

No problem using a splitter and 2 fans. 3 fans starts pushing the limit. A fan header can supply 1.0A. As a rough rule, each fans needs about 0.3A. Any more fans, you need to use a fan hub.
