I have several questions about design of Penta SATA HAT kit with Rock3a
First question is about cooling.
The black radiator plate is designed for rockpi 4, but on rockpi 3a there is no contact between black radiator plate and board (pic1,2)
Anyway, I tested temp with this command
stress --cpu 8 --io 4 --vm 4 --vm-bytes 1024M --timeout 60s
and checked temps with
sudo cat /sys/class/thermal/thermal_zone0/temp
and it was 60C. Is it ok for this cooling setup?
One more thing. As you see in first picture, there is square thermal pad, but in video assembly guide there is no thermal pads. Where I should place that? It is thinner than gap on picture 2 so I think it won’t help.
Second question is about type-c port, which is blocked by case. Maybe you need to make hole for this port in next version of this kit.
Anyway, can I make this port available without drilling case (maybe plume or smth else)?
Third question is for SPI jumper
Should I short-circuit it, as mentioned here (https:// wiki.radxa .com/Rock3/hardware/3a)? Does NAS software uses SPI or flash?
