Current state of art hardware heats a lot more than rb4011, in most modern devices temperature climbs so high that devices are throtling lowering performance to keep temperature under control
there is many CPU working at temperatures as high as 90°C or more and this is considered “normal”
this device consumes 23watt that energy needs to go some where in form of heat
Never rains at everyone taste
Mikrotik makes and designs a solid, powerful, silent and passive cooled device
absent of mobile parts thus less prone to failure because of fan damage
Hello
My RB4011 wifi version is VERY VERY hot, it is impossible to put your hand on, you burn!
I do not find this excessive temperature logical or normal, it is currently marking 51 degrees Celsius, this is not good, such a high temperature will end up damaging the hardware, and it is not a cheap device at all.
Mikrotik has tested this equipment in warm environments? currently in Barcelona (Spain) we are with a very strong heat wave, and I fear for the router, I have had several mikrotik routers (RB3011, RB951G, RB1100AGx4) and none gets so hot
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.
you 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.
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
Hot.. quite interesting. No one told about real data, just 1 post and don’t know with what device it was took. My ex cry about everything is cold and me i was cooking. My rb in system health is at 40dC, room temp at 28.5 quite hot. And with a termocouple K type, a 1/8 of it, i can get a case temp of 22. it’s about 0.5 feet from the floor.
But at same time, if you do multiple vlan and pass all the traffic of multiple network and so, you tax the unit. The rb4011 is not intend for a big buiseness and they do have bigger crs series for that.
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+
I sent supout again, and hopefully MTK will find what is wrong whit it.
Maybe try another power supply and see if you still have problems.
I have seen weird problems with power supplies. Just recently had a weird issue with one of my back haul 24ghz radios, changed power supply and all good. Opened power supply and had bad caps.
RB4011 wireless version
today report 50º, I had to place a fan on top to lower its temperature to 37 degrees
This device has a very serious temperature problem, and I blame it on a design defect, it is not normal for it to be set at 50 degrees, I have a lot of devices at home 24 hours and none gets so hot, it will end up spoiling, and I doubt that Mikrotik covers the guarantee for heat … or yes, because it is not normal !!!
Look. It’s a very high-power CPU and gigabit ethernet RJ45 ports, both sources of significant heat.
They’re packaged in a fan-less form with the whole case working as the heatsink. It’s warm by design.
Don’t panic. The data sheet says the acceptable operating range is -40C to +70C.
