If I only have the three aluminium heatsinks, would any of this be advisable ?

I kind of wonder if you could do a mineral oil immersion with these boards. The GPIO header might be tricky.

Sure, what is different about GPIO vs. ATX power?

The first instructions seem to be, that the cpu is not throttling while idle. So that should be safe. Going forward a fan might be recommended, depending on the usage of the Pi: https://microsoft.github.io/ELL/tutorials/Active-cooling-you... https://news.ycombinator.com/item?id=15487233

Speaking from experience: there’s almost no measurable perf benefit from disabling ondemand governor on Pi3 or other low end boards. I use Pi3 as a cortex a53 benchmark baseline, and I no longer bother controlling the clock.

This does not hold on higher end boards though. E.g. NVIDIA TX1 or 2 is considerably faster if you force max clock.

Unfortunately I don't see any graph as to how much more performance was squeezed out of it, and neither any data of the temperature increased, although in comments I can see people providing some answers with their heatsink and fan set ups. I would be curious to see if this has any improvement for applications such as games in RetroPie.

Since older rpi models can run NES games, I guess the rpi3 is more powerful than necessary. And if the game you’re playing is running smoothly, why bother? With the consoles, there are no graphics settings.

Retropie isn't only about NES. I have a rpi3 and it can handle N64 games too.

There are several emulators available. For example most 2D PSX games work fine. However, most PSP games are unusable due to glitches; N64 games aren't really playable with default settings either.

Getting all N64 games to run properly is a big win. They don't all run all that stable yet.

most likely negative, rpee thermal throttles on stock clock if loaded for more than tens of seconds
