eVGA's e-GeForce4 Ti 4600 follows NVIDIA's reference design to the "T", as most of the other manufacturers have done.
A dominating feature of the e-GeForce4 Ti 4600 is the massive ACS2 cooling solution which was designed and developed by eVGA. They launched their GeForce4 Ti 4600 with the intention of outperforming other cooling solutions by competing with big players such as Leadtek, Visiontek and Gainward. ACS2 is the GeForce4 Ti equivalent to eVGA’s ACS cooling system featured on the e-GeForce4 MX 440. Comments on the ACS cooling system can be found in my comprehensive overview of the GeForce4 MX 440.
ACS2 attracted a great deal attention from the hardware enthusiasts as it not only looks extremely cool, but it contains copper heat pipes, memory heatsinks on both the front and back of the card, and a powerful Delta fan.
Upon examining the ACS2 cooler, my initial impressions were positive and I eventually got around to "looking under the hood."
