Do MBP 2018 has heat and fan issues when plugged to TB3 dock or AC adapter?

Hello, I read that when Lenovo Thinkpad are plugged to Thunderbolt 3 dock or when they are plugged into AC adapter, they becomes hot and noisy. How about the MBP2018?

No noise issues when plugged into AC power here (15" 2.2Ghz). I have it plugged into my LG 5K display and no issues there either. It does get hot on occasion, and it only becomes noisy when it is working hard. But you cannot expect something in this form factor to stay nice and cool when working hard.

Thanks. What do you mean by "working hard"? When it goes hot, it is at the level of uncomfortable or the skin turns red? Does it sound like vacuum cleaner or jet engine?
