Based on the performance gains seen in the various game benchmarks and the major temperature drops, I would say that the modding experiment with the EVGA GTX 970 SC ACX 2.0 graphics card was a success. Its stock and overclocked performance speak volumes.


As of June 01, the EVGA 970 GTX SC ACX 2.0 graphics adapter was available at for $324.99 with Prime shipping. The card was also available from for $309.99 after $15 mail-in rebate and B&H for $337.99 with free shipping.

As of June 01, the WATERCOOL HeatKiller GPU-X3 Core GPU water block was available at for $64.95.


I can say with a clear conscience that this modding experiment was a success, taking the EVGA GTX 970 SC from its decent performing stock configuration and transforming it into a cool-running powerhouse. This type of mod is definitely not for the beginner and should be approached with great caution. The benefits derived are astounding, but the cost of failure is monumental – $300 on a dead piece of silicon that may or may not be able to be warranty replaced is not a good gamble in my book. I wasn't too worried – I've been doing crazy mods like this (and some even more extreme) for many years. In any case, the mod outlined in this article could be applied to virtually any graphics card with some tweaking necessary because of the graphics card layout. The benefit of using a generic GPU-only block like the HeatKiller GPU-X3 Core comes in its re-usability. The full-cover blocks offer direct liquid cooling for the VRMs and memory, but are one-time-use items and not easily transferred to different generation cards (or even across cards of the same generation from different manufacturers).
