Active, of course, means describes the cooling system. Active processor sets have a heatsink and fan, while passive have only a heatsink for cooling. If the Xeon 5120 you are purchasing has a price much lower than the others for sale, make sure to ask the seller and confirm that the item in question does indeed come with an active cooling system, as stated in this items description.
I already have one of these processors and they are very solid. No hyperthreading and only two cores, but they are among the first to feature 1066Mhz FSB and these days you can pick one up for next to nothing. Just make sure it is a retail box kit and not just the processor (unless you already have an extra cooling solution)
