Where do I connect my second fan on my z270m pro4?

Solution
There are 2x 4-pin chassis fan connections. One near the 8-pin cpu connector and one near the 24-pin atx connector.
For cpu there is one 4-pin and one 3-pin fan connectors near the cpu socket

Theres a few fan headers spread around the board, if you have a look in the manual it will tell you where they all are, for now, heres a picture:

Any more than that and you'll need a fan splitter.
