BCC Hardware posted up a review of the Zalman Reserator 1 Plus kit, as well as some other gear.
In this review Howdy Duty compares the performance of this kit to a custom Hydor, BlackIce Extreme, and PolarFLO kit. I know that doesn't seem fair as the custom kit has an active fan, and a nice big radiator, but it's an interesting comparison and the results may surprise you. We show performance using both the active RF1 fan kit as well as straight up and passive.Zalman Reserator 1 Plus, RF1 Kit, & More
