Bashsea smart series sump, fan attachment options?

[dohc97]

I have a bashsea 30" smart series sump and I have figured out I will need to have a fan on over the summer. I need ideas on fans that fit or a way to attach a fan to the sump. Pic is my sump

How about just using a simple clip on fan?

Air King Fan

Great fan from Air King, when space is limited and you want a quick and inexpensive way to cool down your aquarium systems. The Air King Fan is a 6” clip on fan with impact resistant plastic grills. It features a chemical resistant polypropylene blade and a 2 speed 1/300th HP motor.

I don't trust that type of attachment. I guess I can just see if someone can 3d print a bracket for my existing fan assembly
