The Dual-X diverse present in the latest Sapphire Nitro+ cards of the RX 500 series has a completely new design. Dual-X cooling is powered by two massive but silent fans and a cutting-edge design radiator. The new shape of the 95 mm blades guarantees a higher air flow and higher heatsink cover with a lower noise than standard cooling design. The fans are equipped with double sphere bearings, which in our tests have a longer duration of 85% compared to the sleeve bearings. Traditional fans can have up to 10% difference in the number of rpm from one fan to another to the same work cycle. Now, thanks to the new Sapphire Nitro+fan controller, this tolerance is reduced to 3.2%. This improvement in precision guarantees that the cooling and noise performance of each card are up to the standard. W.
