Also, what does socket 370 mean?? will that work with my processer?
Dude you've got a Socket A board.....that answers your question right there...Socket A is usually represented like this "Socket A (462)" so you need to be looking for THOSE socket heatsinks
EDIT: All the fans and heatsinks you've been looking at are about the same in terms of performance. Go with whatever one has the highest CFM Fan is my suggestions since they all have about the same base, a solid copper one.
