Remember how I said I had an issue with cooling my processor? It was because I don't have one of these. The processor I bought came with a stock CPU cooler, and the biggest issue with that is modern games take a lot out of a CPU, especially a cheaper model like the processor I recommend here.
When a processor is under a heavy load, it generates a lot of heat. For example, playing Titanfall 2 at high settings for about an hour and a half gets my CPU's temp to around 200 degrees. This is why an aftermarket CPU cooler is necessary.
Unlike a stock CPU cooler, an aftermarket CPU cooler is able to cool a CPU much more efficiently. They have larger fans and are meant to increase airflow over the central processing unit. This allows fora better-running computer all around.
