TL;DR CPU heatsink screw joints broke off, need to stick my heatsink on cpu with something, does Arctic silver 5 thermal compound stick stuff together or just trasfer heat, if it doesnt stick stuff together, where can i buy a thermal adhesive and which one would be best?

So 2 or 3 weeks ago after an incident with my computer that was fixed by my brother, my computer started to lag suddenly. After the incident it was fine for 2 weeks then suddenly the next day it started to lag, so i thought it was just a problem caused by said incident. Today i find out its probably because my cpu is overheating. So i opened up my computer and saw that the heat sink or liquid cooler (im not sure which it is) somehow got completely ripped off. The limbs where you put the screws in were totally broken apart and I have no idea how this could happen. I have never dropped my computer or ever touched that part of the computer. How could it be so broken apart.

I found out that pushing the heatsink onto the cpu lowers the temp, so the heat sink works, it just has to stick to the cpu. I tried using dental wax to try and over the screw parts, but there still needs to be more contact between the cpu and heatsink. I learned that it used a thermal paste before i took it off. I cleaned it off not knowing what it was.

I searched this up alot and I am still not to sure so I decided to ask you guys:

Does a thermal compound like Arctic silver 5 stick my heatsink and cpu together when applied? If not, then which thermal adhesive would work the best? judging by the copper color of the bottom part of the heatsink where it connects to the cpu, im guessing its made of cupper.
 
Solution
Any thermal compound from a decent brand will do you well, but it won't stick them together. It will only transfer heat. If you're on a tight budget, you could always zip-tie the heatsink on by running the ties through where the screws would go. But of course, if you have the money, a new heatsink would be much better in the long run.
