Router's temperature

RouterOS General
1

Hi all,

I am an owner of the RB951G-2HnD hAP.
I noticed that the temperatures of my device are between 55C to 65C (In summer the room temperature can be high and unpleasant).

Are those temperatures normal? Can it be bad for the long term?
Any original ways to cooler the device beside turning on the A\C?

Thanks

Here you see the reported temperature from my 750Gv3
Its up in the attic, so when sun is shining, temperature goes up.

Thank you for your answer!

I see that the maximum temperature in your (nice) graph is 55C, in my situation the maximum temperature is 65C - a 10C difference.

The question is, in the long run, this high temperatures can damage the device ?

Thanks

I have one day with 66 degree, so have been up in the same range.
High temperature is never good for any electrons products.
Why is it so high? Is it your room temperature? CPU running high?

Can you add an external fan?
Can you open Router add fan/or cooling fins?

Cooler is always better but this temperature is not an immediate danger for the device.

Thank you for your answers guys.
The high temperatures is only due to the room temperature - the CPU load isn’t high.

If you guys having the same temperature with your devices, so I’m gussying I have nothing to fear of.

Thanks

There are several points:

  • a critical internal temperature of the chip above which the chip stops working properly but when it cools down it starts working fine again, which may be even above 100 °C,
  • a “melting” internal temperature of the chip which damages it irreversibly, which may be somewhere around 130 °C,
  • temperature which shortens the life of the components, and for this one no “safe” value exists - the higher the temperature, the lower the lifespan of components, especially of electrolytic capacitors.

So below 70 °C indicated the only thing to think about is the aging, and it is a matter of economic calculation whether it makes sense to run the air conditioning or whether it will be cheaper to replace the box after, say, 5 years of operation. Somewhere in between is ensuring forced air flow without a heat pump (i.e. just a fan, no A/C).
