Yep!! I saw some one have this some where so i did a search and downloaded it

I think I am going to get some heat sinks fro the DTS chip and the main CPU. They get really Hot and I can see then solder getting soft
if on for long periods of time.

I have read where some have installed a small fan. Anything to try to cool them down is good.

What's the best way to adhere them to the chip?

Thermal tape

like this

www.mouser.com/ProductDetail/Bergquist-Company/BP100-0005-00-1112/?qs=sGAEpiMZZMsiS1%252bJOF5PnzhRg4pM%252b3qps6OMFyHHue0%3d

or you could have bought heat sinks with the adhesive already attached.

I was looking at this one

www.mouser.com/ProductDetail/Advanced-Thermal-Solutions/ATS-52170P-C2-R0/?qs=sGAEpiMZZMttgyDkZ5WiumGsSiMtK5Z6ju64rm%2fuMJc%3d

Its 11.72, 10 or more are 8.82 maybe we can get 10 to split the cost. I'm sure she can use them somewhere else.

Ok So I had time to get some heat sinks and install them on my Onkyo's

I thought both Heat sinks came with adhesive on them but only the larger one I ordered did. So I just used some double sided mounting tape from 3M I found at
Home depot. Its a little thicker than I like but for now it is still allowing the heat sink to conduct some heat to it from the chip.

On my next order I'll get the proper adhesive.

Any problem with the cover clearance?

the larger one is getting hot. But that is not the chip that causes the audio issue.

I think the smaller one would benefit from a better specific adhesive. I was going to try silicon, a very thin film of it.

But what I did notice is that where that chip is located the cover above it does not have any slats in it to
allow heat to rise out of the enclosure. I bet drilling holes in the cover right above that chip would help keeping it cooler.

No issue with clearance either.
