Do you mean something like
these?
You may have to get more than one kit since nowadays graphics cards have more than 8 pieces of VRAM (also called BGA memory). Bear in mind, though, you can't just reattach your stock heatsink with these in the way. So I hope you've got a GPU-only waterblock or aftermarket air-cooler of any type with enough clearance. Of course there are many different profiles to try out, shop around before you buy.
Also since in most ATX cases, the card is upside down, make sure you've held each heatsink with the appropriate down pressure so that when you install it, nothing falls.
