To make sure that this card performs well under a load, Sapphire slapped a massive Vapor Chamber-based cooling solution on the card. The combination of Sapphire's Tri-X dual ball bearing fans and Vapor Chamber cooling solution make this card one of the coolest running cards I have tested, both stock and overclocked. What makes this cooling performance that much more impressive is that the power consumed by the card is in excess of 300 watts stock and overclocked. Impressive indeed. Planning for the future, Sapphire has made its fans replaceable without removing the shroud. Simply remove two screws, lift out the dual ball bearing fans, and reverse the procedure to put it back. Simple as can be. To help tie the video cards cooling performance to the case cooling, Sapphire has added the Turbine X feature to this card. You can connect up to two case fans to the card that intelligently manages the fan speeds based on the input from five thermal sensors on the PCB. A pretty cool feature, but not really necessary as many cases and most motherboards have PWM controlled headers to manage cooling performance.
