Help finding 40mm 24v fan

[bartsarzy]

I am in need of three 40mm 24v fans for my 3d printer. The ones on there are a bit loud and finding a quieter replacement seems impossible. I want to avoid making a step down from 24 to 12. Does anyone know where I can find the quietest 24v fan with at least 5 cfm?

I've looked at frozencpu, performance pcs, and other random websites.

Thanks for the answer but unfortunately that louder the current fans on there, I should have included the db of the fan on the printer in the original post. So the current fans, according to the manufacturer is between 26 and 28.
