This ensures reliable operation with the next generation of processors and graphics cards.
Silent Wings Fan
Provides virtually inaudible operation
The high-end Silent Wings fan delivers best-of-class airflow yet produces very little noise. This is thanks to its unique, optimized fan blade design along with an advanced fluid-dynamic bearing and 6-pole fan motor that largely eliminates operational noise, has a super-long life and minimal
power consumption.
Flawless Cooling Concept
For a longer lifespan
The funnel-shaped fan inlet of the Straight Power 12 850W increases airflow while reducing unwanted turbulence for a higher cooling performance. The wire-free design inside allows the cool air to reach all components which ultimately leads to a longer lifespan.
