Does Thermal Paste Lose Effectiveness Over Time?

post #1 of 3
Thread Starter 
Does thermal paste lose effectiveness over time? I can't help but feel like my CPU's idle temps have been gradually going up over the years with no real change in system setup or ambient temps.

Thoughts?

I think most on OCN including my self are of the opinion that thermal paste does degrade dry up over time reducing its effectiveness. As far as I know there is not study on the subject so I won't claim it as fact but there have been more then a few case where swapping out old paste has yielded better temps. But that improvement could be due to other factors besides degraded paste like the new paste being of an better grade then the original ever was or the new paste being better applied or the cooler setting better.

I hear ya. I can't help but feel it would lose some effectiveness over time, but there definitely are all those other outstanding factors you mentioned which might skew any kind of testing results.

Thanks!
