linux novice needing a bit of help

hello all,

I have begun a retropie nespi+ case build with a standard raspberry pi3 (non + edition) and have ran across a few cooling issues during file transfers over the network.

the nespi+ case only fits a 30mm fan and i seem to be having issues finding a quality and quiet 30mm fan and apparently noctua doesn't make them (I'm unsure why).

This led me to a search for a pi case mod for a 40mm fan and i stumbled across the following:

https://medium.com/@olilay/how-to-keep-your-raspberry-pi-cool-and-quiet-with-a-smart-fan-ecd15f4dbf7b

i decided i like this idea and to see if there was a way to adapt a 40mm fan to the 30mm fan location on my nespi+ case and found this:

https://www.thingiverse.com/thing:3223501

so now it appears i have figured out everything i need to to make a 40mm fan work in my nespi case and not only that it will function as an actual computer cpu fan by accelerating when temperatures require it to do so.

this is where i need some help, I'm barley a novice with linux....like i copy and paste things into the command prompt because i have a hard time retyping them or do not know what to type to get the required results.

the instructions for the "smart fan" are written for an at the minimum intermediate user with a base knowledge expecting someone to know certain commands (editing txt files for example) that i do not have.

I as hoping someone would be able to simplify this so that i am able to have the gaps missing that i need to understand and perform the modification.

my first major question until i get to playing ith this and looking at how it works:

how do i install the .deb file? i know retropie is written on a heavily modified debian kernal so this should be able to be adapted to work how id like it to. what i do not know is the commands to type to have retropie obtain the .deb file and install it.

and second....im assuming that the GPIO pinout for a pi4 is the same for a standard pi3?

RetroPie is not 'written on a heavily modified deboan kernal'. It's just a collection of scripts installed on-top of an existing Linux operating system (Debian or similar distro). A .deb file is a Debian package which can be installed using dpkg - see https://man7.org/linux/man-pages/man1/dpkg.1.html.

Yes.
