Electric fan is much better than clutch fan. Although the key is to get an inteligent and reliable switch as clutch fan works harder, spin faster under load. Keep the original fan shroud is also important.

Electric fan reduce a lot of stress on components like water pump ...etc. I used to run them on my semi track R32 GTR and performance improvement is noticeable, acceleration and stuff.
