Talking of balance I fitted a four blade fan many years ago without considering balance. It turned out to be badly balanced and the fan spindle broke at 60 mph on the M3 going to Beaulieu. Also it was a 3 blade fan after that and I had a leaking radiator! The lesson is do check and correct the balance before fitting; the supplier may not have done.
