In short, why does the the TV doesn’t need a fan to cooldown and PC requires one while dealing with high definition videos?

I assume “processing” means playing the video and not using something like handbrake to encode the video before playing it.
If your GPU heats up when playing an 8k video you either have hardware acceleration enabled on whatever video player you’re using along with other real-time post processing effects (think madVR), you have an older GPU that can provide HW acceleration for 8k videos, but the onboard ASIC is very inefficient and or has limited support for 8k videos so it heats up tremendously when used for 8k videos as a result, or the GPU has to encode/transcode a video file into an 8k format in real time that your gpu can provide basic HW acceleration support for (this can also be related to having an older ASIC on the GPU that is inefficient or has limited 8k video support). TVs don’t have this capability; they play whatever signal is sent to them as is.
TL;DR your GPU heats up playing 8k videos because you are using it to play the video, and something is telling it to do computations on the video file youre watching. TVs cannot do this.
