The fans in front of the radiator are very inefficient....apart from looking the part they blow very little air through the radiator... to start with the centre of the fan blows no air you only finish up with a ring of air blowing into the radiator...cooling a very small area of the total area of the radiator .....the only way to get air pulling evenly through the whole radiator is to have the fan on the back and a shroud must be used to pull air through the entire area of the radiator...... not just in front of the fan...
