The package includes a dual-fan aluminium fin heatsink, EVGA claims it's up to 15% quieter and delivers up to 15% lower GPU temperatures and 7% lower MOSFET temperatures than the stock cooler.
The ACX for GeForce Titan Black is exclusively available as a DIY solution because NVIDIA forbids its add-in board partners to ship GeForce GTX Titan Black cards with custom coolers (full-coverage waterblocks being the only exception).
