> Although I've never been conscious of pump out as a problem, and have never reapplied thermal paste,

I’ve had problems with both pump out and other thermal paste aging problems.

The problem is very different across thermal pastes. Some of the high performance enthusiast market pastes I’ve used have started out great and then degraded until I was having problems a few years later.

My feeling is that the engineers and OEMs understand these tradeoffs better than the hobby market. All of those boring pastes that came in OEM configurations but underperformed the latest $20 tube you could buy in the aftermarket were just making different tradeoffs.

The newer pastes have been better for me so far. The person who made this video also does some testing that’s supposed to simulate pump-out and maintains a database of pastes which has been helpful to finally have after all these years of relying on forum anecdotes for everything.
