Question 2/4 case fans working

[lunchboxd]

I recently did an upgrade from a GIGABYTE B365M D3SH WIFI to an ASUS TUF GAMING B560-PLUS WIFI everything works fine, but only 2/4 of the case fans work. Anything I can do to get those other fans working?

Follow the fan wires and look where they are connected. Probably loose connector, if even plugged in.
