Do you have a 2nd, 3rd, or 5th generation AMD AM4 processor in your gaming PC? Choose an AM4 processor cooler. With an AM4 cooler, you know for sure it fits. In addition to actively cooling your processor, it also increases the lifespan of your CPU. You actively lead away hot air and heat, which means your processor can keep running without slowing down. Again, these processor coolers are only compatible with AMD Ryzen processors from the 2nd, 3rd, or 5th generation. Be sure to check this before your purchase.
