The reason its noisy is because its a 4 blade fan. |

There's a nice explanation of the noise levels for the various types of fans here - http://www.minisport.com.au/category3_2.htm |

I take exception to the 1st line in that Minisport ad, sure they were designed for Australian conditions: In 1965 we got a new improved radiator with 16 gills (fins) per inch. Was still a 3 core but cooled much better than the previous ones. As for fans, I believe the original 16 blade metal fan on our cars was an Australian design, then adopted by the Poms. IMO it's still the best/quietest for a road car. 
Cooper S overheating in traffic? that's a /flame subject for another thread..

I think the four blade fans will only go on one way? And yes they are very noisy. |

Yes, the 4 blade can only go in one way. |

Cheers Guys i was pretty sure that it was correct... but i thought i best just to check .. would a six blade fan be better for air movement ? just trying to chase a heating issue, Beanie |

I would look at whatever is causing the heating issue. The fan is not causing it to overheat. |

For what its worth I love my 4 blade fan, pushes a shiteload of air, noisy? Yep, can I hear it over the sound of a fat Weber and exhaust? Nope 
As others said sort the rest of ur cooling first, flush and reverse flush everything, use a good, real coolant (ones that you have to make up are good, little bottle of tectaloy gold is great) well sorted radiator, good working thermostat should make it cooler for ya! |
