It was the stock cooler that came with the prebuilt I had purchased during a time of chip shortage, buying a prebuilt during that time was cheaper than buying parts and assembling a computer yourself. At least it was for me, anyway. Long story short, I figured for such a cost they wouldn't fuck my cooling and I was wrong. I only upgraded it now because I've started playing more graphically intensive games that'd benefit greatly from a higher cpu clock rate. Previously, I was forced to set my clockrate to a lower value to avoid throttling, but I can let my CPU run at its maximum now with the upgraded cooling which nets me around 20 to 30 frames on average in graphically intensive videogames.
