You get no shade from me. My only beef is with programmers who act like they are experts in all things computer when they aren't.

BTW, the issue in the picture is that the CPU cooler is attached to the wall of the case instead of the CPU. It shuts down because modern hardware will usually turn itself off when it overheats to mitigate the risk of permanent damage.

Wisdom is knowing what you don't know.

The big silver heat sink that's on the left is meant to be on the CPU, which is the Silver squarish shape towards the right. Keeping the CPU cool is a big deal — CPUs come with a smaller fan which is sufficient for many people, but people who use their PC more intensively, or want to extend the life of their CPU typically buy an additional cooler. Here's an example of a stock cooler, and here's a motherboard that's using the fairly basic aftermarket CPU cooler that I have. It was only $30, but when I was new to PC building, it was strongly recommended, because if your CPU gets too hot, it'll throttle itself and slow down. People who over clock their CPU (running it at a higher voltage for better performance) have to get even beefier cooling, such as water cooling. You can completely fry your CPU if you do something wrong when overclocking, and even if it doesn't get that bad, minor mistakes can cause crashes due to CPU overheating.

So TL;DR: keeping your CPU cool is super important for both performance and longevity of the CPU.

The PC in the top photo has zero cooling for the CPU. Not even the stock fan that comes with the CPU. That heatsink that's attached to the case fan is almost certainly intended for the CPU — you don't even need a heatsink in that location.

This means that this person's CPU will rapidly overheat soon after it is turned on.

Edit: you can actually see where the heat sink should match up to the CPU here

Ah btw, the thermal paste is only supposed to fill the microscopic surface gaps, so please add only a tiny bit and don't spread it around (creates air bubbles while adding the sink). A rice grain worth in size and form in the center is enough. This also presses the air out on fastening the sink.

I'm sure there are great screenwriters who don't know the first thing about cameras or projectors. They can still write good screenplays.

Do you want the spoiler

We're looking at a hardware issue. What would a programmer care?

Then you're a typical programmer, at least in my experience.
