The hot setup in the hot rod field is a two speed fan from an 89 to 95 Ford Taurus with a 3.8 V6.Do not get one from a 3.0 engine,they look close but not even close in CFM. Low speed is about
3800 CFM and high speed is a whooping 4500 CFM.
I have one in my IMSA Fiero and only use the high speed.Nothing on the market to compare.
Just Google Taurus 3.8 liter V6 radiator fan and you will find a lot of info
You can get them at a yard for about $35 or buy new.You just need to trim the fan shroud surround and it will fit the Fiero.You will need a relay rated for 80 amps to handle it.
Good Luck.
