correct as Robert said.. the small fan is blowing a concentrated wall of cool air onto the hotend to stop the heat from traveling from the heating cartridge up the hotend... possibly allowing for the PLA filament to expand in the Bowden tube and stopping the flow of material.
So a bigger fan for this purpose is not needed !

It's not meant to make the whole assembly cold. The purpose is to create a sharper temperature transition for the filament so that it doesn't clog.
Are you having issues with your prints?
