Ohhh I can’t buy it. It has a Amlogic A311D,not supported by FreeBSD…
Radxa Zero 3W temperatures too high even using the heatsink created especially for the radxa 3W
Just confirming the Radxa heatsink for the Zero 3W is kind-a worthless. After monitoring / logging for a few days without and a few days with heat sync. Below are the results.
Without heat sync average CPU temp 140F / 60C, average CPU utilisation 6%
With heat sync average CPU temp 137F / 58.3V, average CPU utilization 6%
OS is Radxa Debian CLI with just about everything unnecessary stripped out, and just running my own service.
For reference, a Raspberry Pi 2w in the exact same setup is 134F / 56.6C (Running exact same SW, but Raspberry OS). CPU utilization was 5%
Using the configuration below my radxa does not exceed 60 C running with FreeBSD in idle and with a low load :
Never tested if I stress it a lot. yeah,can reach 70 C. I know that the only method to keep the temp all around 50 C is to use these ones :

but then the board becomes not usable for the FreeBSD based phone that I’m building.
No one saw a phone with two cooling active fans
