Can someone explain these pieces of aluminum foil glued down to the fans in this 2012 MBP 15" non retina I just got?

Are these aftermarket fans or something? What is this?

Looks like an old patch job to me...
I bet if you carefully clean that tape off the fans, you will find damage underneath. The plastic shield on both fans appears to be melted a bit.

Compare yours to this picture of the same 2012 15-inch internals:

Yes, I guess so... but these fans aren't THAT expensive to replace, are they? Sheesh! What a weird find inside this MBP!...

I'm more interested in the story behind this weirdness, asking the seller to please explain...

No, not that expensive, about $40 a piece on iFixit.com. But my question is; does the computer work? The machine is 10 years old now, so hardly surprising to see some kind of damage.

I'm typing on a 2011 15" MBP that works flawlessly.

I don't know if most people on MR know this but the non retina 2012 MacBook Pros were sold new by Apple through about 2016 because they were such good computers.
 
Not sure if I agree with the idea: "they were such good computers"

Only the 13-inch was sold as new (still being manufactured) until late in 2016. (The 15-inch was discontinued in 2013.)
That was the last Mac that Apple sold with an internal optical drive, also easily upgradeable RAM and storage drive.
So, common to swap out the optical drive, and have two internal drives - again, the last Apple laptop that allowed that choice.
I would think it was demand-driven, and Apple continued to sell that model far longer than most any Mac for quite a few years (other than the 2013 MacPro, you have to go way back to Apple II/III)
 
My 13" 2011 MBP still works flawlessly, depending on what I'm trying to do with it. Basic web browsing, playing music with iTunes, no problem. But trying to build modern Wordpress websites with it doesn't go so well, and the latest Adobe apps don't work at all on it.

But I do think that for a computer to still be usable after 10 years makes it a very good one. My first laptop was an HP Compaq Presario 15" with Windows 7. First battery died after a year, second one, also a year. Within those first 2 years, screen problems that I just couldn't figure out, even with the attempted help from a repair shop. I could also go have breakfast while I waited for it to boot. My 2011 MBP battery lasted 9 years and went over 2000 cycles before it started to show any signs of weakness. I eventually replaced it myself for €80. So yes, these were the last truly user serviceable Macs that Apple made.

it may have been a refurb but I know of 15" MacBook Pros 2012 non retinas that sold through the end of 2014 and manufactured through mid to late 2014.

My main computer right now is a 2011 15" MBP that Apple replaced the bad video chip in 2016. Still runs like a champ.
