Zywall USG 20 fan operating logic
Hi, I'm from Italy, excuse for my English…I have found 2 old Zywall USG20 (firmware update to last release) that everyone has the fan which start ad stop in loop every time.
It's a normal operation?
Thanks you for the attention and best regards.

When the temperature of the device exceeds the limit temperature, the fans will turn on.
When the fans cool the device below the limit temperature - they will turn off.
In my USG210 it is like this: https://community.zyxel.com/en/discussion/1181/usg210-temperatureRegards

Thank you for the answer.
My firewall is EOS, therefore isn't safe?

@Cesare2 You can check the hardware temperature by debug hardware fan-get
The safe value should be under 70°C

Current days are "normally hot" in italy. USG20 is a really old device, therefore maybe the thermal media between heatshink and cpu is closer to destroyed than in service.
Consider a thermal media replacement, if you know how to do it.
