Twin Frozr III Thermal Design pushes Temperatures Down to 65°C MSI's Twin Frozr III cooling design has proven its worth through rigorous testing by professional media. The unique Propeller Blade technology, patented in multiple countries, incorporates special air-flow channels into the edge of the fan blades to not only increase cooling coverage but also boost air flow by 20% over conventional fan blades for even better cooling! Under a full load, the core temperature of the MSI GTX 650 Ti BOOST Twin Frozr graphics card is just 65°C and noise during operation is only 25.37dB as well, clear proof that MSI products not only help gamers stay cool but also keeps the noise down for the best user experience!
