Elegoo N4Pro upgrade with Volcano and 3x5015

Good afternoon

This question has probably been asked thousands of times already, but still

I have Neptune4Pro, I would like to change the hotend to Volcano and install a 3x5015 airflow

Is there any guide for green noobs like me, preferably with pictures? I could print model and buy volcano, but how to set things up - big question for me...

Or, if anyone could help, I would write such a guide, photographing and documenting everything during the upgrade process

Seems it is the only model i could find -> https://www.printables.com/model/1294309-neptune-4-35015-printhead-volkano/files

And seems there no remix of such with this one? -> https://www.printables.com/model/905447-sf-3x5015-neptune-4-fan-mod-shroud-optimized-enhan

Thank you very much
