I bought a restored MacBook Pro 15 2015 (MacBookPro11,5). And noticed a strange behavior: 1) Fans are very noisy. For example, if i watch a video on YouTube 4k 60 fps, then the temperature of the processor reaches over 60°C and the fans are running at full capacity. It even happens that I just sit in the browser and the fans start working abruptly (although the processor temperature at this time is 50-55°C). 2) If I have a charge the battery on the MacBook less than 100% and it is turned off, then when connected to the charging, it automatically turns on. Is this normal behavior for the MacBook?
