Just learned that through reddit, I thought they worked kinda like paste and needed to be changed regularly.Not really something that often gets noted even if a site takes the card apart. Just measure them yourself when you get it. Though you'd be just as well leaving the current ones in place really. The soft ones that almost all graphics cards use aren't something that wear out. It's only those annoying hard, clay-like ones that are found on cards like the reference Vega 56/64 that are a pain in the bum, since they tend to break up when you remove the cooler. Or the fabric ones that Nvidia stick on their reference cards for the same reason.
