As usual, we always try to make hte most powerfull graphic card compatible with our Mac as silent as the entire Mac Pro itself, in order to continue enjoying low noise computing while having such 3D beast inside. We have repalced the original cooling system with a ventirad Artic Cooling Twin Turbo, then modified a bit the default procedure to further improve its efficiency.
We also tested this new system after overcocking the Radeon HD 4790 in a Mac Pro.
