I'm in the process of building a new system (P4 2.8 on an Asus P4C800-E board) and I want to run the system overclocked to FSB1000 to take full advantage of a pair of Kingston Hyperx PC4000 (DDR500) 512 DIMMs. Will the packaged hfs be able to handle the overclocking, or will I have use another cooling system? If the latter, what will do the trick at low cost?
