CPU thermal paste

Just out of curiosity are there any sure-fire ways to tell if your CPU already has thermal paste? I know some have paste on it with a little plastic piece covering but I'd just like to know of any other giveaways.

The metal-to-metal contact between the CPU and the cooler cold plate is not perfect, and that's where the paste comes in. It's vaguely analogous to lubricating something like a piston in a cylinder, the piston and cylinder are close to perfect but not quite, and the lubricating oil prevents hot-spots. Similarly, the thermal paste fills in all the little airgaps making them much more thermally conductive.

If your CPU has no thermal paste, I'd expect excessive idle and load temperatures.

The CPU never already has thermal paste on it it comes with the cooler.

If they were no paste under your cooler it would overheat really quick.

I mis-read your original question. CPU's never have paste pre-applied as far as I know. The CPU cooler might, in which case it would be obvious because there would be gunk on the cooler mating surface instead of a smooth shiny surface.

I do not know short of searching for the cpu and add 'thermal paste' at the end. "amd ryzen 3600 thermal paste" I know all of the AMD CPUs that have the Wrath cooler have thermal paste applied to the cooler, and I am pretty sure Intel's do as well.
