My mom wanted a new cooler, her slot is an AM3+ AM3b, Bought a liquid pump that supports it, It comes, It comes with the clamp but not base to screw in that the clamp things can clamp onto? I don't understand, If it supports the socket, Why is there no base for the clamps with the cooler? My personal pump came with the sort of ( type things you screw in to let it latch on, but this cooler didn't. Why?
