Im going to be making a hdd block soon, after ive finnished some others. Im thinking about how to do it. id like to combine this type of mounting

with a way of silently cooling the drive enough, so that when its wrapped in foam, it wont overheat.
On my drives, currently mounted in a steel drive cage, the sides are not very hot, about 45c, but a few chips are about 65c
