After like a minute or two, the fan turns on and starts working where as when I'm watching videos, I hardly ever hear the fan turn on.
I ahould clarify, by "everything I've used kodi on" I mean 2 devices lol. A windows 8 laptop and my current chromebox openelec
From what little I understand...
Kodi is not doing any rendering when watching videos, just passing the media stream to the onboard decoders via the graphics drivers (if accelerated in hardware) and the hardware taking care of the display refresh for rendering the video. This is fairly efficient on modern CPU/GPU hardware and why even the weakest of the boxes can play full 1080P HD videos without showing strain.
The Kodi rendering happens when you have the Kodi UI components - panels, controls, dialog boxes, overlays, artwork, etc. From what little I understand, this is very CPU/GPU intensive for historical/legacy reasons as Kodi itself keeps refreshing the screen for the UI components. They have done some optimizations to only refresh parts of the screen that changes but that still takes significant CPU/GPU resources. How much of that is avoidable, I would have no idea.
