Bought, installed, configured. Everything is fine, I liked everything until the problems started. The temperature is high and sometimes it happens to him that it does not suit me at all. He freezes. Yes, it hangs so much that it’s not winbox, it’s impossible to get through to it. And in appearance, the lights are on and everything seems to be fine. You have to reboot it through the power supply. Once and it didn't work. Turned off for three hours, and then only he came to life. I put a USB fan on it and the temperature is 35C. Works. That's just putting a USB fan is also problematic, since it does not have a USB port. I wrote to mikrotik. Com technical support, but they can’t say anything reasonable there either. Now I think where it is and what to replace it with. Ready to discuss with you if anyone needs one. )
