What replacement fan do I get for it?

I have an HP Notebook - 15-ba079dx (Touch) (ENERG... (Seriously, name's so long it doesn't completely list). Its fan, I believe, is in need of replacement. It had been replaced before, but I can't exactly afford $130+ for a shop to do it for me. I have an all around good set of tools bought from here before for other fix it projects, I just want to know what fan part to purchase to do the fixing myself.

The only HP laptops listed here that I saw were a digit or two off (15-ba078dx & 15-ba0709dx).

Last thing I'd need is to get the wrong part.
