I have a 10 year old AV receiver that I opened to de-dust. I noticed that on
the heat sink there a black foam material running across the top length of
the heat sink. The foam looks like double-sided foam tape, but is sticky on
one side only.

I'm not sure what the intended purpose of this was, and if I should attempt
to repair/replace it with something else as it is cracking off.

I could use regular foam double-sided tape, but imagine that the heat sink
get very hot and the tape would get unsticky very quickly.

Any thoughts on why it would be there in the first place, and what to use to
replace it.

If someone sat on the amp would the heatsink touch the casing?
