I am in the process of building a small server based on the SC5650DP enclosure and the S5520HC mainboard... But since the boxed E56xx CPU's doesn't come with a CPU cooler, I need to figure out which CPU cooler(s) to use.. Initially I was considering BXSTS100C - but if the enclosure already have a fan duct - will a passive CPU cooler be ok ? If yes, what is the part number for this/these ?
You can use either STS100C (up to 130W) or STS100A (up to 80W), based on your CPU. See page 28 of http://www.intel.com/support/motherboards/server/s5520hc/sb/CS-030226.htm Spares, parts list and configuration guide.
