A shroud should cure your problem ,I have a 17 in fan and a hand made shroud ,I made it to fit full core size for extra cooling note notch for radiator hose,,works fine now even at idle ,I also changed my fan temp switch to come on at 185 ,not at 210 like the original that came with the fan,i have a 4 flu aluminum radiator ,and a BBC,the black strip at top of shroud is not a gap it is a rubber door edge guard to keep the shroud from rubbing the radiator.
