When you print my cover for the 60mm fan, there is enough place to take a 60mm x 25mm. (at least i hope you don´t have a different PSU, because they change it from time to time.) But the holes are made for the Noctua. I don´t know if they will fit for every other, but if not, you can glue them on, or use cable ties.
Just try them, and if it won´t fit, send it back or cut some holes.
