So today I found out that my thermal paste never came into contact with my CPU due to the cooler not being mounted properly.
This was the thermal paste that was already applied to the CPU cooler when it arrived. This also means that because I have never replaced it, my CPU has not had thermal paste for 3 years!!!
For anyone who is interested, after actually fixing the issue I saw a drop from 90°C to 35°C idle.
My question is how has it survived this long without breaking?
Also the best guess at how this CPU will die (when it does(probably soon)) can have it.
Also sorry if this is in the wrong place or is uninteresting as this is my first post.
