When below the required temperature, the fan still spins for a certain amount of time to assist in cooling. https://github.com/pymumu/fan-control-rock5b/blob/main/src/fan-control.c#L50-L56 The longest time is 180s

There is a minimum current requirement for fan spin. the pwm value of my fan is 5500, it stops when it is lower than 5500. You can adjust the initial...

这些功能都是适配openwrt官方代码的，其他衍生代码没有验证过，这些衍生分支请咨询对人的维护人看如何添加

Not tested on rock5A, so might not work, and I don't have rock5A either, cannot modify the code. You can read the official guide to turn on the fan. Maybe,...

you can run the following command, and attach the log. ``` fan-control ```

默认是先ping，200ms后会用tcping:80，在200ms后tcping:443，都ping不通，就会优选一个IP地址。这个优选的策略是，命中次数最多的IP。

ping不通的情况下，响应会变长。这里一个优化点是，如果所有查询结果只有一个IP地址的情况下，是不进行测速的。 对

默认情况只要上游返回ipV4，也一定返回ipv4给客户端 那个开关开启后，v6速度比v4快时，v4会返回SOA
