Know you of such a thing? I'm packing up a GUJ hard drive enclosure, and it contains dense, black, thermally conductive foam around the edge. I no longer have access to a spectroscope sadly, so can't tell what it's made of. It definitely exists though 
Anyone know of an equivalent? Be amazing if it was noise dampening as well, but just thermally conductive will do for now.
Cheers
