I once inherited a PC from my older brother, he had built it himself and i decided it needed a sping clean. I opened it up and airdusted with the help of an old toothbrush, but couldnt get some fluff/dust out of the CPU cooler so i took it off to get behind it properly.
The little plastic cover over the thermal paste was still on the heatsink sandwiched between the heatstink and the CPU.
He hasnt heard the end of it.

It is surprising and Im sure it reduced the performance, but plastic still conducts heat and sounds like it was a thermoplastic and it didn't melt.

Wow. I'm surprised it worked for so long. I assume there were issues, such as high temp, that your brother didn't diagnoze or didn't know how to. Impressive that CPU is working all those years. Any damage to its function?

Back in the 00s, a story about CPUs getting so hot they'd start on fire went viral. In it was a video of someone removing the cooler while it was running and then a few seconds later a flame appears.

On the one hand, obviously you shouldn't remove your CPU cooler while it was running.

But on the other hand, fans and mounts can fail, so this was still a risk even for people who were smarter than removing the cooler entirely.

It prompted CPU makers to add thermal protections that started out as "if CPU hits threshold, cut power", but over time more sophisticated heat management was integrated with more sophisticated performance and power management.

So these days, if you aren't sufficiently cooling your CPU, it won't die much quicker, instead it will throttle performance to keep heat at safe levels. OP would have gotten better performance out of it after removing that plastic. Assuming it was CPU bottlenecked in the first place. Things like RAM choice and settings can make it a moot point because the RAM can't keep up with the CPU at 100% power anyways.

Post his phone number so we can all tell him about it.
