The fan speed of Sapphire is intelligently controlled to keep the GPU, memory, PWM IC, and other components as low as possible in temperature to balance performance, and fan noise. Standard industry fans may have up to a 10% difference between fan rotation cycles (RPM). The Fan IC Control on SAPPHIRE graphics cards reduces differential at approximately 3%. The SAPPHIRE graphics cards are designed with robust VRM cooling and have a high thermal conductivity pad on the back plate to take away the heat efficiently and effectively. A robust memory cooling solution has been integrated into each SAPPHIRE graphics card to cool down memory with a specially designed independent cooling module. SAPPHIRE's acclaimed Dual-X Cooling is powered by two massive yet silent fans and a state-of-the-art radiator design which results in greater airflow and superior heatsink coverage at lower noise compared to standard cooling designs. The all-aluminum backplate provides additional rigidity that guarantees nothing bends and dust stays out. It also helps cool the user's card by increasing heat dissipation. Dual Ball bearing fans have an approximately 85% longer lifespan than sleeve bearings in our tests. To protect the user's card, the SAPPHIRE cards have fuse protection built into the circuit of the external PCI-E power connector to keep the components safe. Choose between performance mode or silent mode to enhance the user's gaming experience. Customize individual style with TriXX Software and heighten the gaming experience. Gain FPS by slightly decreasing resolution that is then adjusted through image sharpening for a more immersive gaming experience with much more fine-grained control over the quality vs. performance tradeoff. designed with Phase Digital Power specifically for GPU and memory to aid in overclocking, balancing current distribution, and averaging thermal dissipation for each power phase. Redesigned the airflow so that the hot air is expelled through the system fan instead, rapidly dissipating heat, and includes a tunneled fin with tiny holes which increases the convection airflow. This Sapphire Pulse Radeon Graphics card comes with 02 years of warranty.
