Fuse protection In order to protect your card, the SAPPHIRE NITRO+ series cards have fuse protection built into the circuit of the external PCI-E power connector to keep the components safe. Precision fan control Standard industry fans may have up to 10% difference between their fan rotation cycles (RPM). With the new Fan IC Control on SAPPHIRE NITRO + graphics cards, this differential is reduced to 3%. This 70% improvement on accuracy ensures that cooling and noise performance of every NITRO + card is up to scratch. Robust VRM Cooling The SAPPHIRE NITRO+ cards are designed with robust VRM cooling and have a high thermal conductivity pad on the backplate to take away the heat efficiently and effectively.
