Is there a fan off another tractor that provides more airflow than stock 4020 fan?

M&W made a seven blade fan and shroud for their turbo setup.It moves much more air than the five blade.

I had an M&W seven blade fan & matching shroud on my 4020 and wasn"t very happy with it. The M&W fan was 19", the original 4020 fan is 21". I now have a 6 blade 21" fan from a 2940 and am using the original 4020 fan shroud. I also am using a water pump pulley from a 4010 which is smaller in diameter, increasing the fan speed. The 2940 fan throws more air than the M&W did.

There were some combine fans that some used.The best way we have found to eliminate cooling problems has been to have radiator checked out.
