Its not a cooler.....!!!! Thats something you keep your beer in! Its a HSF or a heatsink and a fan... (you'll understand if you watch the video) The clock divider is cool though. Its something that not a lot of athlon motherboards support. The Iwill XP333 supports this as it is the only way it can run the fsb at higher speeds without overclocking the AGP and PCI (AGP usually a 1/3 divider and PCI 1/4). 150 fsb on a standard 266DDR board means a 37.5 PCI bus which usually runs at 33Mhz. Not all PCI components are happy running at these overclocked rates so user definable dividers solve this. I believe this technology was a long time coming as its not a simple thing to be able to do on a motherboard.
