High performance 14cm fan with S-FLOW blades supplying 30% more airflow than a standard fan at the same speed. The greater performance combined with PWM automatic speed control allows the fan noise to be kept to a minimum.

The Viper fan creates more focused airflow providing blind-spot cooling, which makes it an ideal solution for a case or heatsink fan. HDB (Hydro Dynamic) bearings extend fan life and further enhances noise reduction. Killer Viper yellow color makes this fan distinctive and unique.
