"Replacing thermal paste is also necessary once in a while." Er, no. Only if you move, replace, or otherwise dislodge the heatsink.

Yeah, thermal paste does decay, and under high loads, continuous operation and dusty heatsinks it decays faster. In general server heatsinks do not require maintenance as much as e.g. gaming GPU would, but they still do need maintenance, esp. when you get a second hand box or take over an operation that's been maintained by god knows who

"Does decay": Hm.. citation needed.
And if it decays due to dusty heatsinks then it's not closed, it's been dislodged, and that's a different case obviously.

Well, to be specific, oil-based compounds do not decay, or at least do not decay meaningfully. Other types of paste may. WIth GPUs a factory based paste can expire within 2-3 years of intermittent use, especially if the heatsink isn't cleaned with dust. With server equipment I had it happen maybe twice, with very old boxes, so maybe at year six or so you might wanna start reviewing boxes for elevated temperature...
