Review on be quiet! Pure Rock 2 Black: 150W TDP CPU Cooler with Elegant Black Surface and HDT Technology by Alejandro Lane

So far it has already lowered my CPU temperature by 8-10 degrees Celsius compared to the stock cooler for my Intel i7-1100. Installation was pretty easy with their YouTube videos or printed instructions. As a beginner builder, I want to watch a separate video with fan installation tips. I watched the main video and dented a few fins while trying to manually snap the fan back into place. The fan installation tips provided in a separate video made installing the fan much easier without damaging it. There's a very slight hum from time to time as the fan revs up to full speed, but it goes away when it hits maximum RPM. It's not really that loud, my only criticism is that I want a completely silent car. That may be because I accidentally bent a few slats at the edge. Otherwise it's really quiet. I love this darkened version of the cooling fins. It would be nice to have some ARGB to give it a slight flare, but that's just a secondary thought if cooling is the primary concern. I would recommend buying it again.
