High tg copper pcb the gpu is mounted on to the high density 14 layer 2oz copper pcb with a high tg temperature value pcb to match the power requirements of the gpu and memory and guarantee mechanical stability of the pcb during operation. Fuse protection in order to protect your card, the sapphire cards have fuse protection built into the circuit of the external pci e power connector to keep the components safe. Intelligent fan control fan speed 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 precision fan control standard industry fans may have up to 10% difference between fan rotation cycles rpm. The fan ic control on sapphire graphics cards reduce differential at approximately 3%. This up to 70% improvement on accuracy ensures that cooling and noise performance of every graphics card is up to scratch metal back plate with thermal pad the high quality aluminum back plate is not just for styling, it also protects the components on the back side of the pcb and help dissipate the heat from the pcb with high performance thermal pad in between. Two ball bearing fans these feature dual ball bearing fans, which have an approximately 85% longer lifespan than sleeve bearings in our tests. The improvements to the fan blades means the solution is up to 10% quieter than the previous generation. Angular velocity fan blade the angular velocity fan blade provides a double layer of downward air pressure which alongside the air pressure on the outer ring of the axial fan, results in up to 44% more downward air pressure and up to 19% more airflow for a quieter and cooler operation when compared to the previous generations.
