You're reffering to a stock heatsink or something better? the fact that you're asking for a heatsink for an X2 5000+ I suspect its a black Ed. thus came without HSF and you intened to push him (otherwise why buy a black ed?). I have a stock heatsink that will work as the black ed is a 65nm part and runs cool at default. Let me know if you're interested of if you're looking for something more like a XP90 etc.
