The little memory heatsinks sold in computer stores fit the small Tripath chip perfectly, and they have a "thermal" peel & stick adhesive on them. The ones I got were a cool-looking anodized blue, and were about $10 for a pack of eight. Running the amp, they do warm up, indicating the heat is flowing away from the chip.
A more geeky solution is JB Weld, a metal-filled epoxy. Geekier still would be to grind up a little silver on some fine sandpaper and add it to the mix. Careful not to get the metal-filled glue on any of the electrical contacts.

BWRX said:The poor man's approach is to just "secure" the heatsink to the chip using an audiophile grade rubber band
But will it provide proper dampening for the heatsink, so as not to induce spurrious vibrations into the audio chain?
