The XSPC Raystorm 420 EX280 Universal CPU Water Cooling Kit comes complete with everything you will need to cool your CPU. This kit is designed to handle your CPU and can be expanded to handle more blocks as well. The kit uses the newest XSPC CPU block, the Raystorm as the core cooling component. This block has a pure copper base and is a top of the line in performance and looks. XSPC coupled this with their 280mm EX280 radiator which is a thin profile radiator giving more flexibility with compatibility. The X2O 420 is a compact, low power pump / reservoir design that offers greater head delivery than our X2O 750 pump and at a lower noise level. The single 5.25" bay design makes it an ideal pump for mATX and ITX builds and it"s still powerful enough for any full size ATX build.
