I received my order of the Bergquist thermal interface sheet. Yes, sheet. Singular. I failed to click on the link for what was meant by "Standard Package". It doesn't mean that YOU get 100 sheets, rather, that's how Digi-Key gets them from the manufacturer. So I got one 4" square sheet for $33. My own damn fault. I hope I can do something useful with it. No, I'm not going to try to return it.
Maybe I can sell small squares of it. I'll try an experiment to see if it does anything useful on my Mini 9.
Amusingly, I managed to convince DowCorning to send me a sampler of their brand of thermal gap filler material. (I work for a company they do a lot of business with.) They have some 20+ styles in various thicknesses and properties. The samples are about an inch and a half square. Only a couple appear to be applicable to the Mini 9.
