CRS125 temperature spike

Hardware MikroTik hardware general

Hi,

I - by accident - discovered something weird with my CRS125-24G-1S-2HnD.
Every couple of hours, the temperature spikes to 60+ degrees Celsius, and then the next check (polling interval of one minute), it’s back to normal.

Time					 Temperature
13/08/16 20:56		39
13/08/16 20:55		61
13/08/16 16:31		38
13/08/16 16:30		63
12/08/16 13:29		38
12/08/16 13:28		62
11/08/16 21:46		38
11/08/16 21:45		61

I checked the following, during the spike:

  • There is no spike in CPU percentage.
  • There is no spike in input Voltage.
  • There is no increase of memory usage.
  • None of the interfaces show increased traffic.
  • No scheduled jobs.
  • No other Mikrotik (I have 7) show this behavior.

Could anyone explain this?

It may be the same bug as mentioned here?

I think the best way to resolve this is to send a supout.rif to support@mikrotik.com to check it.

Maybe, I have sent support an email with a graph, this URL and the supout file.
Will report back when I hear from them.

The temperature sensor is only an approximate guide, not a calibrated instrument. The earlier devices had tendency to spike sometimes, so I suggest configuring some kind of averaging, and dropping shorter spikes from the graph. Maybe it is possible to tell your software to store the average of 30seconds or so.

Ok thanks
