I have a corsair h100i, I had this pc for 2 years now plus what the previous owner had it for I cant give you a actual time frame of how long i had this for but in the last week i have been hearing really bad rattling noise and squeaking noise coming from my cpu cooler block and my cpu temperatures idle around 80c and whilst doing something not even tough on the cpu it will rise up to 100c instantly.
Cpu : i7 4770k (not oc)
