Need help about deepcool-s case fans

Hey everyone, I want to add more fans of the same type to the bottom of my case, but I can’t find them being sold individually anywhere.

I did find some similar-looking fans from no-name brands listed as Prism-7 Pro fans — are these the same or at least compatible with what came with the case? Has anyone tried using them, and do they match the lighting/connectors/airflow?

I can't find the RPM details of the prism 7 fans, not sure if I'm connecting them on my fan hub will cause any issues / noise
