Do thermal pads significantly get worse over time?

    In the past days I have been looking all over the net to find out if thermal pads lose conductivity over time (e.g. 4 years) or not. But I could not find any answers besides differing opinions.

    My question is if TP's get noticeably worse (performance/conductivity wise) over let's say 4 years and have to be replaced. Or do TP's keep their performance for longer and the old ones should therefore still be sufficient?

    I am wondering because I never replaced the stock thermal pads of my 7970m over its vRAM modules and vrm's.

    If someone knows anything about this matter I would really appreciate an answer ;)

    The stock thermals pads on my GT80S turned into a chewed bubble gum after 1 year.

    I would say it degrades the same as thermal paste over a longer period.

    So you would have to replace the thermal pad maybe after 2-3 years compared to thermal paste 1-2 years.

    Some thermal pad are wet type, have grease on them. If the grease dries then maybe the conductivity is lose? Such example is the cheap generic pads you can buy on ebay.

    Then you have fujipoly which is the dry type, not sure how to gauge this one but could last longer?

    Arctic pads are in the middle of the spectrum.

    Aren't thermal pads always like this (consistency wise)?

    Did it cool less after that year?

    I think he meant the thermal pad become really soft and you can break with no effort at all, probably dry too.

    The stock MSi thermal pad is quite firm and oily.

    Why have you posted this question multiple times? Spamming is not allowed here. I answered you already.

    This.

    There is a slight increased in temp 3-4C.

    Sorry, I posted it in two forums because I didn't know where this question actually belongs.

    I didn't mean to spam and I know it's not allowed, just didn't know which is the right place to ask?!

    Either one was fine. Replying to a post in 2 forums with the same reply is fine if it's relevant to the topic (that's not spamming) but making the same topic in multiple forums is spamming.
    The right thing to do is to delete the topic, but if that's not allowed, just say something like "sorry, mod please delete" or something. Other people may not even see the thread with more replies and then you have clutter and someone has to merge them.
