The cooler inside is the NH-D15 AM4 and it is giant, took up a lot of space, and increased the weight. It is way better than what was inside and much quieter too.
The sticker on the bottom says "AMD Athlon, Whoop Ass Inside!"

This used to be my Dad's PC and it used to have the old Athlon processor, but now it has a Ryzen processor. My friends and I call it the sleeper, because I do not have any RGB colors in the build and it is also in an older case (lian li pc-68).
