It looks similar to Thermaltake's Blue Orb. The heatsinks dimensions are 54.6x12.7mm and the fan outputs 12 CFM @ 5000 rpm's with a decible level of 28dBa.. Now this might not seem like a lot. But given the size of the cooler it doesn't need much. Most stock chipset coolers only put out 4 to 6cfm if they are that lucky so to jump to 12 is a pretty good jump.
