To protect your card, the Sapphire cards feature a fuse integrated into the circuit of the external PCI-E power connector to safeguard the components. The composite heat pipes are finely tuned for each individual cooling design to ensure optimal heat flow, efficiently and evenly distributing heat across the entire cooling module. The fans are equipped with dual ball bearings, which have shown to last about 85% longer than sleeve bearings in tests. Enhancements to the fan blades mean that the solution is up to 10% quieter than the previous generation. The fully aluminum backplate provides additional stability, ensuring that nothing bends and dust stays out. It also contributes to cooling your card by increasing heat dissipation.
