just the one, sort of.

I have bought loads of them, and if you buy 2, you actually end up with enough stuff to cool 3 sticks by using the heatsinks (not the spreaders) 2 each side of a ram stick. it looks quite awesome, and works rather well. but other than that, i wouldnt bother with spreaders at all, unless you are brave enough to *LAP* your ram sticks and use arctive silver epoxy mixed with arctic silver 5. thats the only way i have found to get any actual performance gain out of them. the active cooling kits are bit better, but you still have to go through the same proccess.
