My MBP (2017 no-TB) runs significantly hotter when plugged into my Anker dock and powering my Samsung 1080p display. The laptop is closed in this configuration, so it's only running one display either way. But it's 10-15°C warmer when plugged.
It's possible this is because the closed lid keeps heat in. I've also heard that using any external display requires the laptop to use its discrete GPU, and this generates additional heat.
Either way, it's pretty annoying because the laptop starts throttling itself with very modest usage.
