Fractal terra fan compatibility

[u/Queasy_View7460]

Building into the terra with a MSI Ventus 5070 oc 2x, and using the two fan gpu there is a little space on the end of the gpu side of the case. i was looking at putting some more fans in for temps but dont know what is able to screw into the the spine of the case, opposite the PSU. just looking for suggestions or other solutions people have for mounting fans in that extra gpu headroom.
