Over the years, I’ve heard numerous stories about thermal paste drying out after a few years, and that it would effect temps. Is this really true? I have a medium level 5 year old W10 build, used for routine computing. HWinfo 64, has shown idling levels at 32 to 35, all this time, and 72 under stress. These numbers have not changed over the years.
Usiing Noctua, don’t remember which one. Any reason to remove and reapply, and does the paste really dry out?
Routine computing doesn’t really cause the thermals to rise above normal. The higher the heat, the quicker the degrade.
I also, either request or use quality paste in which contributes to longevity.
I have a secondary PC that was used for gaming and now is a Linux box that runs distributed computing software and its going on 11 years.
Absolutely agree as well.
If you have ever removed a processor from its heatsink on an old PC, you’ll find the paste is firm and even crumbly instead of being smooth like toothpaste.
Already answered your question here but alas you did not feel that my answer or that of others were worthy of any acknowledgement
Good quality thermal compounds will when correctly applied most often last the lifetime of the computer and so never need replacing unless the heatsink gets disturbed or removed, short version, if you have not disturbed the heatsink/s on the CPU at all look at other possible causes of elevated temperatures.
The only thing that may influence the above is extreme overclocking.
