1. You are complaining but not sharing temp reported on system health menu, please share to have an objective view of the situationHello all,
I recently bough a new RB4011iGS+5HacQ2HnD-IN and before i had the chance to configure it, the metal became extremely hot ( just at the point of burning your hands ) and we still haven't reached this summer..
I understand this is to dissipate the heat but i would like to ask two questions as i am considering returning it:
1. Is it possible ( currently or in a near future ) to lower the CPU frequency with RouterOS or make some other configuration to prevent it from heating this much.
2. is everyone having the same experience?
Hi team, I was tasked to evaluate the RB4011 before investing in more units.
This unit feels warm to the touch, even at zero load/shutdown.
Our unit is running RouterOS/firmware 6.43.14
1) we performed a System > Reset Configuration
2) no clients connected with LAN or WLAN
3) the unit was tested sitting in an open space on a table top with at least 2m clearing in all directions
4) the ambient air temperature was 23.5°C
Test #1 - with the unit powered on, we measured the external temperature at different points on the metal casing at 5 minute intervals after boot:
Time after boot / case temp
5 mins / 28.4 °C
10 mins / 33.0 °C
15 mins / 35.3 °C
20 mins / 37.0 °C
25 mins / 37.8 °C
30 mins / 38.6 °C
35 mins / 39.0 °C
40 mins / 40.2 °C
45 mins / 40.2 °C
50 mins / 40.4 °C
55 mins / 40.8 °C
60 mins / 40.8 °C
Test #2 - logon to the unit (winbox) and shutdown the unit. Our expectations were that the temperature would drop to ambient room temperature as the unit was now powered down (but still connected to PSU):
Time after shutdown / case temp
1 hour / 43.0 °C
2 hours / 43.5 °C
3 hours / 44.5 °C
4 hours / 45.0 °C
10 hours / 45.0 °C
I would be very interested to hear if the above observations are expected?
You are completely right! I didn't think about that potential issueyou need to buy hardware for the installation, not just for the specs. If you are working in hot environments with no natural airflow / air-con then you will need active cooling, so buy a model with active cooling (RB1100AHx4 would be my suggestion). There is more to product selection then just specs, ports and functionality.
Hrmm i swear I remember fan holes on the back of 1100 case - maybe im thinking older model? My bad.Be careful choosing device, both RB1100AHx4 models have passive cooling!you will need active cooling, so buy a model with active cooling (RB1100AHx4 would be my suggestion).
OK. I will do that. Thanks...I don't think the crash was due to temperature. The device can easily work at higher temperatures. make a supout.rif file and contact support, it could be another reason
case has fan holes but not fans, only 20 watt no need for active cooling but maybe you can adapt a fanHrmm i swear I remember fan holes on the back of 1100 case - maybe im thinking older model?

4011 blocked again, and weather is cold in Serbia. So blocking wasn't temperature related. I am changing it tomorrow for CCR1009-7G-1C-1S+Hello,
It's very warm in Serbia and my RB4011iGS+ blocked twice in 3 days. This time I put him in Librenms and last temp before crash was 66C. It was maybe higher, but 4011 didn't report it. I could ping device, but traffic stopped and only remote gsm reboot saved me from traveling to this remote location.
I will have to mount some kind of fan to it.
Really? Your RB4011 was cooler than the ambient temperature in the room? This can't be correct data.My RB4011 is in an upright position, which gives it more ventilation. It was a very hot summer in my region - +50 in the shade.
The temperature of the router did not rise above +44.
Temperatures for devices like this, using a higher power arm processor, are known to be hot, they are designed for this.
Lets compare it for instance with a raspberry pi 4 board, that can run as hot as 80 degrees celcius and that still is no problem at all.
One of the engeneers of the board even said the device can run for longe periods with temperatures around 90 degrees.

So please don't worry about 50 or even 60 degrees on the RB4011.
