Overclockers Online posted a review on the Ultra Aluminum Hard Drive Cooler
I'll be honest to say that I was quite surprise by the results. The idle temps were nearly identical but to see a 5 degree difference in load temps really surprised me. The numbers obviously speak for themselves and Ultra's Aluminum Hard Drive Cooler with Heatpipes obviously does its job well and pretty much matches the results of the stock setup in the Cosmos.Ultra Aluminum Hard Drive Cooler Review
