This! Got a used AMD-K5 PR133 in a big-tower a long time ago, integrated it into my home lab, and used it to experiment.
About 1 one year later it underwent my cleaning routine, vacuuming dust out, cleaning the fans, etc. I took the cpu-cooler off to check for bad thermal grease and discovered it had none at all! No pad either, someone just clipped that thing on, and instead of direct contact it had a small airgap which you could look through from the sides.
Unbelievable.
When I got it, it must have been in use for years already!
