Is a heatsink for the top of the Rock Pi 4 in design? I have placed 3 small heatsinks on the WiFi and two other IC’s around it. These IC’s get quite warm and I am concerned about long term thermal degradation to these parts. Also, I have the large heatsink for the bottom. I see two small issues.
- The gap from the memory chips to the heatsink is quite large. I was able to measure, and the gap is .037".
- There is also no provision for cooling the eMMC module. I have already machined an aluminum piece to take up most of the gap. I plan on using thermal gap pad to address the memory and eMMC chip gaps.
Hopefully this helps improve the product. I may even decide to design my own top heatsink, but it will take quite some time due to my schedule.
