"The aluminum hard drive cooler from Ultra is not just eye candy and, as stated on the box, it is highly efficient. The cooler preformed better than I thought it would and in doing it should extend the life of the drive thanks to the lower temperatures. The performance comes at a price though, the MSRP for the cooler is $43, now granted, for that amount of money you're getting a nice part that looks as good as it performs. With a little shopping you should be able to find it for less as PriceGrabber has them starting at $19.99 thanks to a $5 rebate..."
