If you count the air on a non-watercooled gaming PC it comes to around 85% or 90% of volume used for cooling too. If you pack a watercooled PC as tight as possible including the radiators it's maybe 70% of volume dedicated to cooling.
This things run for hours and hours, it's hard to understand if you just use your computer to do cloud things or maybe compile something every once in a while. I'm into photography and I've been learning Ableton and my Mac wasn't doing it anymore, after an hour the fans go super loud and the CPU underclocks and Lightroom or Photoshop become super slow and Ableton starts clicking. I got a Thinkpad T where like 50% of my laptop is now cooling and I can work on it for hours and everything runs fine.
