Legion Hardware has just posted a review on Thermaltake's new HSF unit called the Volcano 9.
Performance wise the Volcano 9 was always just a few degrees behind the SLK-800 and the cooler has much more to offer on a value basis. The Volcano 9 is also a reasonably attractive cooler sporting a kewl orange fan and a chrome fan shroud mounted on the silver heatsink. Added options such as the fan speed control and temperature sensor are the icing on the cake. I was very surprised to find that the function two (temperature sensor) worked really well.More information at Legion Hardware
