When I shipped back my defective board (due to flickering display), the thermal pad was seemingly affixed to it, so I didn't bother removing it. However, the replacement board that arrived did not have a thermal pad on it, so I'm currently idling around 62ºC and afraid to stress the PBP any further until I have a solution for the missing heatsink...

The thickest I'm finding on retail sites is 1.5W/mK @ 4mm and 5mm thicknesses. 6W/mK are seemingly at a thickness of 1.5mm or less, which is certainly not enough to reach the bottom chassis of the enclosure... I did take pictures of my board before I sent it in for testing/replacement, and I can guesstimate it is likely a 4 or 5mm pad, but I'd rather have some assurance before I waste $10 on a guess.
Would it be possible to temporarily assemble it with a blob of BluTack in place of the pad, then dismantle it and measure the Blu Tack thickness?

Not a bad idea - if only I had some of that laying around.
