According to the firm this should perform better and be more quiet than conventional heatsinks, while being safer and easier to install than real watercooling kits.
The Revo weighs only 330g and features an aluminum radiator with hundreds of fins which is cooled by a silent 92mm fan.
The cooler supports Intel's LGA775 and AMD's Socket AM2, 754, 939 and 940. I heard a rumour that the cooler will be available for about 45EUR.
