Ultra Aluminum Hard Drive Cooler Review
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...
