Hello.
I have a Dynatron T319 CPU cooler, here's the PDF:

You can see there's a thick layer between the radiator and the CPU, and there's a seal on the top left of the photo, I suspect the material inside the thick layer is the same fluid in the laptops' heat pipe.
I don't understand why it have such a design, as metal have a much higher heat transfer speed than any other common material(and that's why we shouldn't apply to much thermal grease). The only reason I can imaging is that layer increase thermal capacity, but I don't think high thermal capacity is even needed for a CPU cooler.
Also, the most thing I'm worrying is the life span of this, since I've seen some laptop's heat pipe lose seal thus no longer work in just a few years, although that's a low quality one.
Welcome to discuss these.
Thanks.
