1. Much thermal energy is moved from the system-on-a-chip (soc) to 's sides and back. Then 's sides and back are touching the lower-️ air and the lower-️ hand. Part of the design is that the air and ️ will lower ️ of the sides and the back.

2. Or, the soc is overheating and is at moving thermal energy away from the soc.

3. Or extreme overheating. is moving much thermal energy away from the soc but it isn't enough to normalize the soc's ️.

The idea can be applied to and ️. if or the desktop's case is blowing notably high-️ air –

1. great cooling system (fans, heat pipes, vapor chambers)

2. or extreme overheating (the cooling system is doing its best but not enough)
