Interesting but quite neutered in stock mode ain’t it?
I gotta get me some of that silicon carbide stuff (that others have mentioned in potting driver mixes) and mix it in with some 30min epoxy and stuff the pill behind the star (give it a bit more meat to soak up the heat)
And/or some ultra-grey sensor safe RTV from autozone (or the silicon caulk from the post…duh 
)
Either way…that thin “pill” if you want to call it that definitely doesn’t look like it would wick heat away hardly at all
here is 18sixfifty’s review and take on it
