SG-3100 expected idle temperature
« on: November 06, 2017, 10:02:30 am »
Hi,

My pfSense is reporting an idle temperature of around 70 C, this is with load average of 0.16,0.18,0.17 and CPU of 10-15% (I guess this is being affected by my observation, as I have the web dashboard open which is obviously using up some cycles too).

Is this a "normal" temperature? It seems a little high for me, but I'm not familiar with the hardware...

On a related note - can anybody tell me the SNMP OID to monitor temperature?

Thanks,
-Alex

It depends on a lot on the ambient temp and what it's doing, but mine goes between 60c-70c or so. It's usually around 63-65 completely idle, with no traffic other than me watching the dashboard, and that's today when it's a bit chilly in here (~70f/21c ambient in the house this morning). Mine is on a shelf next to some other gear that gets fairly warm though.

Ok, so with that in mind, an ambient of around 23 C, and the SG-3100 sitting between above a Netgear switch and a below Speedtouch modem (which does get quite warm in itself), 70 C or so should be expected...

I have my 3100 set to "Hiadaptive" and it idles around 58c, but when I am pushing traffic it will typically go upwards of 68c.

Mine is located in my basement, on a wire rack with lots of airflow.

I did have mine located on my Ubiquiti 150w switch and it was pushing 70c so I would say this is normal.

Can't say much for pfSense/FreeBSD on ARM - but this is "normal" for Linux on the Armada 38x under typical loads in similar use cases...

Wouldn't worry too much about it - well within design spec of the SoC.

It depends on the ambient temperature without a fan. My office is @19c at the moment so my SG-3100 is idle @53c.
