IDK bout small PC type fans that plug directly into a socket. I just bought to 80mm High output PC fans and a 12v power adapter from RS, wired it up a plugged it in.

Maybe one of the small $6 fans from Wally World and cut the whole just right and tape it in?

4" flex duct fits nicely around 80mm PC fans too
