So, i've been playing on my computer for about 2 years now, and suddenly from one day to another it starts lagging in games and going slow, so i restart it, and it tells me error, cpu is too hot or whatnot. So i dust of my fan and radiator, and put on some new thermal paste. problem isnt gone, so i figure it probably is my watercooler that has broke, but how can i be sure it isnt cpu malfunction? without picking the cooler apart.
Btw its currently as im writing this running at 75 C with no games open

Just fyi, when i looked at the cooling plate on the Cpu, there was a small scratch or hole on it, is that supposed to be there, and can it be alarming?.
Thanks for the answers! :)
