InsaneTek has posted a Cooler Master Dual Storm Fan review

Today, we have up for review the new Dual Storm fan. What's so special about this fan? To answer that question, we must go back in time and try to remember the intentions of the Y.S. Tech TMD fan. Regular fans are designed with the motors in the center, and consequently, an O-shaped dead spot with no air movement is formed. Although current heatsinks are designed to help spread heat throughout the fins, the center of the heatsink base is where the most heat is absorbed. Even with the new CPUs coming with integrated heatspreaders to help dissipate the heat across a larger surface, the center is still the hottest part of the CPU. Going back to the TMD fan, the TMD fan was designed to focus airflow straight down to the center. Air doesn't get blown around, but is directed towards the middle. It was certainly the ideal fan, yet, it was supported by poor construction design. The motors were placed at the corners of the fan and caused many fan shortages during use. It happened to many people, including our resident review editor. The shortages ruined the TMD fan's reputation and led it to be discontinued. After two years, Cooler Master has brought back the idea of center focused airflow with the creation of the Dual Storm.
