What kind of heatsink do you recommend for heavy compilation tasks?

The NVMe SSD can go under the big heatsink or over the top, so should not interfere with the cooling of the Rock Pi. Thermal pad or Heat sink is available for the SSD too if needed.

I cant say how much the USB 3 gigabit ethernet adapter or USB 3 802.11ax adapter would heat up, thermal pads or small heat sinks could be used there too.

If thermal dissipation is needed, can mount it on the side or use a small quiet fan like the one suggested by Dante earlier. I would recommend the Rock Pi acrylic case too, it adds structural integrity to the whole setup. :slight_smile:

This thread has some nice info regarding cooling solutions and cases:
