MSI Explains Their “Propeller Blade” Technology

On paper they claim that it allows 20% more airflow and wider ventilation angles in contrast to traditional designs, and it can reduce temperatures of up to 21 degrees. This means longer hardware life, more overclocking potential, and of course an overall cooler PC. So one might ask how all this works? For starters, there’s the curved angle and arched edges intended to enlarge the angle of airflow direction. There are also rounded edges that lowers noise. MSI says that grooves in the specially designed propellers increase airflow range, while small arcs generate more airflow. Lastly there’s a gloss coating which serves the purpose of reducing “wind” resistance.

So how do all these tweaks and enhancements stack up? The company said their very own R6870 Hawk with Twin Frozr III ran 21 degrees cooler and 7dB quieter than a reference version. Look for MSI’s Propeller Blade technology on new Twin Frozr III and Cyclone II video cards. Hit up the clip below.
