Raspberry Pi 3 - Idle/Load temperatures while running Retropie?

@caver01 Just to finish the off topic then:
Yes, the video player you use will also influence the heat and performance. VLC is not hardware accelerated, so it will tax the CPU quite a bit. depending on the video resolution and frame rate, you may find that the videos don't quite run as well or as smooth as in other platforms. This will result in the CPU heating up quite a bit more than otherwise.
OMX Player is hardware accelerated, so it should run most videos - even at higher resolutions - quite smoothly and without taxing the CPU. This won't cause as much CPU heat.
That being said, it seems that it doesn't do well with some specific video encodings - I found that as well with some other videos.
My recommendation, if you'd have the patience and chance to, would be to run them all through Handbrake or something - even if using VLC, I'd recommend doing so and reducing them to a max resolution of 480x360@30fps for better performance with VLC.
Anyway, end of off topic.

@hobnob Late reply (since I'm new to RetroPie), but "me too."
Here is my kit.
The base of the case is quite warm and the little rubber feet that come with this kit were not raising the case far enough above the surface I was using (as part of the problem). I'll look for other solutions, but given the amount of heat at the touch, I believe the case is at least part of the issue. Heat sink adhesive is probably part of the issue, though I'm noting the recommendations to ditch the heat sinks altogether.

Going to try this case since the fan blows on the chips and allows exit below (though a side or back vent might be more efficient, but would dork with the case esthetics...).

@monkeydisco don’t give up on heat sinks. They can help a lot (they do in my setup). But use a thermal compound instead of mystery tape.
