Overclockers Online has published a review on the Evercool H.D.D Air Condition

The Evercool HDAC is a very straight forward hard drive cooler that mounts in an open 5.25" drive bay. The aluminum body is solid and does a good job drawing heat out of the hard drive and the turbine fan performs very well and nearly silent at lower RPMs. In a tightly packed case or one with no front fans, this hard drive cooler can really help keep the hard drive with all your precious data nice and cool. This will extend the life of the drive and help prevent an early failure.
