My Mikrotik Hex is 5 years old.
Not long ago it began to work unstably - periodically rebooting, I noticed that its 24 volt power supply produces about 10 volts. And I didn’t like the temperature >60 degrees.
I changed the power supply to a new 24 volt. The health system showed exactly 24 volts, but the temperature rose to 70 degrees and remained stable at that level.
I thought that there might be problems with cooling the processor and either I need to install a radiator or change the paste.
Having opened the device, I discovered that the problem was not in the processor.
It turned out that another element was heating up. When I tried to glue the radiator to it, it fell off. Judging by the legs, it was not soldered very well.
After soldering it, the problem did not go away.
When powered by 24 volts it heats up to more than 100 degrees, and when powered by 12 volts it heats up to 60 degrees.
Tell me how normal is this? What could be the reason for this phenomenon? what can be done about this?
