3D Game Man posted a review on the Ultra Aluminum Hard Drive Cooler
This cooler actually does work. It lowered our drives temperatures down a whole single degree both at idle and at load. Now this obviously is not a huge performer. This cooler, while building upon a great passive theory, does not hit the target when it comes to real world cooling. As for sound absorption, there really wasn't any, but then again, there wasn't any addition noise created by the drive cage.Ultra Aluminum Hard Drive Cooler Review
