assuming by “processing” you mean playing a video, then your GPU is probably broken or the manufacturer got dumb and didnt include fan-stop mode. so when doing very lightweight work, like playing a video, the fan still spins. both PC GPU and TV have special hardware that’s super efficient for playing videos.

the ELI5 is:

both TV and GPU have a person, let’s call him/her “Vidmaster” who is very smart/capable/efficient in playing videos. so this vidmaster can do the work required to play videos without sweating at all. So Vidmaster can work with comfort even without the air conditioner being turned on.

the problem is that some office (in your case, a PC) didn’t have the ability to turn off the air conditioning. so when vidmaster is working, he/she is stuck with the air conditioner turned on.
