I recently picked the COOLER MASTER Hyper N 520 RR-920-N520-GP 92mm Sleeve CPU Cooler fan/heat sink after the fan on my ARCTIC COOLING Freezer 7 Pro Rev.2 92mm Fluid Dynamic CPU Cooler died. It's been preforming nearly as well, the old Arctic keep my CPU around 37C idle and 45C while gaming while the Cooler Master has been just a bit higher on idle, around 41C and still close to 45C gaming. The installation was infinitely easier than the Arctic which uses those cheap plastic snap in clips which need so much force to snap in that it feel like the motherboard might crack in two. The Cooler has a range of mounting components, which are much easier to screw on. It came with some thermal compound as well, but I used Artic Silver 5 compound instead, but I can't image it's any worse. The instructions however I think are a bit lacking, and despite installing the cooler exactly as is illustrated in the instructions, the airflow seemed to be reverse of what was shown. The temps seem to be within a normal range but the instructions could be clearer to avoid this confusion.
