Question Issues about meaning of "n" in msi gs70 laptop fan

[Sebass123]

I have an msi gs70 laptop to which I must replace a fan, The problem is that the model that comes from behind says "PAAD06015SL" but it also says "n269".The problem is that searching the internet, I find other fans that have the "PAAD06015SL" model but the "n" is different, for example I find "n285", "n229", etc. I really don't understand what the "n..." contributes, I'm commenting on this because I can't specifically find the "n269" and I wonder if there will be a problem when buying the same model ("PAAD06015SL") but that it has another number corresponding to the "n"

I did look, I couldn't find anything.
