I'm still pondering over the cooling options for the
ATI TV Wonder USB2.0n
I did find the case incredibly easy to disassemble, single machine screw and no plastic tabs to break.
Once inside I found the ATI Theater 200 chip generates almost as much heat as the Phillips Tuner.
I found some $1.00 raspberry pi single chip heatsinks with thermal adhesive that perfectly cover the surface of the Theater 200 chip.
I also found some $5.00 (and 5 volt) dc fans that can probably be driven off small wires attached to the 6 volt connector, with a small resistor or trimmer to shift the voltage slightly and vary the speed. It would only be dropping 1 volt and a very tiny amount of current.
I'm thinking it can hang out on the outside of the case with the antenna plate removed and possibly held there with a little gray square or rectangular abs plastic channel tubing

Rather than drill or glue it to the case, a washer and nut could hold the addon to the unit, if I drilled/dremeled a hole big enough for the antenna stud and tightened the nut down over the washer and on the antenna stud.
The opposite side of the antenna stud would provide an exit space for air flow, so the pattern would be swoop down into the cavity on the Right side, guided by the Phillips tuner wall through the Theater 200 heat sink fins, around the Phillips and back up and out the Left side. Further trimming and grooving the abs channel tubing piece might make a tighter custom mating fit with the opening in the box around the antenna stud.
The fan would only gently increase the air pressure and be fairly quiet, squeezing the hot air out, since the Phillips tuner generates the majority of heat, it would have the most overall surface area in contact with the moving air flow.
Its all theory right now, lots of things I'm thinking about.
I got the idea from a soccer mom with a Storm Trooper helmet, using some of these fans with a couple AA batteries.
I have to be careful though that I'm not over thinking it.. I do that a lot.
