Yes, assuming the controller is not using a switching buck/boost circuit, then the output can only be as high as the input. But, you tried running the fans from 5v before and they didn't want to start. So, if that's the case, then the controller must be outputting more than 5v.

Trying to get it a bit quieter
This is my "silent" build, and I feel getting it down to ~7V would be perfect when all I'm doing is writing up an essay..
The airflow is very powerful on low on 12V.
Well, when I mean I ran the fan on 5V, I meant through the controller.
I guess next time I'll try fan directly on 5V to settle this debate!
