[Cerowrt-devel] trying a pcengines box

[Luis E. Garcia]

Regarding the thermal envelope for the SOC on the APU2 - it's good up to
100C so 60 degrees is well below the threshold. I've read that some people
have had good results by skipping the thermal pads and applying thermal
paste instead between the SOC and the heat spreader - I haven't tried this
approach yet, but I'll give it try once I get to Central America and it's
tropical weather.

The APU1 runs a bit hotter at around 77C when the CPU is under load for an
extended period of time. But I've never had any issues - I'm tempted to try
the thermal paste trick on this one first.
