question about EMD Blade Q Fans for emd GP38-2

question about EMD Blade Q Fans for emd GP38-2 most of JRs GP38-2 seem to use EMD 48in 8 Blade Fan,<kuid2:45324:85305:5>, except for the ICG GP38-2 uses the EMD 48in 9 Blade Q Fan,<kuid2:45324:85309:5>
is this an oversight or do some GP38s or GP38-2s use the EMD 48in 9 Blade Q Fan,<kuid2:45324:85309:5>

Try to change the kuid numbers in config.txt under Mesh table attachments and see what happens.

I believe it varies between phases of locomotive.

I don't know either, but I would say the 9 blade adds better air flow

This shouldn't be. It wasn't that way on mine when I made it. <kuid2:45324:85305:1> is what it should say.
