[QUOTE="Digerati, post: 699908, member: 59833"] It depends on the processor. There are many current processors that generate a lot of heat at default clocks. The Ryzen 7 1800X, for example, tops out at 95°C. But that is really immaterial since we must go by the processor being used - which may not be a current model. And what matters most is to just [I]use[/I] TIM [U]and[/U] apply it properly. Even basic silicon paste is much better than nothing and it is better than the best TIM that's been applied improperly. That may be but it was not because your old paste was "old". The cured bond was broken, the case was full of dust, air vents or air filters were clogged, the heatsink was caked with dust, the case was not providing a sufficient flow of cool air, the CPU fan was not spinning up to speed, the voltages were off, clocking was done improperly or any combination of the above was affecting temperatures which caused the throttling. Not the TIM getting old. Some TIMs are certainly better than others from the start. And all TIMs degrade a few degrees - but that is typically less than 5°C. If 5°C makes that big a difference, computer heat management was not adequate from the start and heat related issues were likely present, or imminent from the start too. So again, if replacing the TIM alone provides the few degrees below the CPU's threshold to prevent thermal protection from kicking in, there are more problems than just the TIM (assuming it was initially applied properly and the bond is still intact).
