Ok well that all makes sense as silly as it must be. That's an outrageous price for a 670 and anyone who would want to purchase another to SLI is most definitely better off upgrading to a single newer card of course. I have looked into the over heating issues with the EVGA acx cards (as with any new pc purchase I google the product and add 'problems' to see what comes up) and the over heating issue seems to mainly revolve around the FTW versions. As posted in another forum (http://forums.evga.com/Is-the-EVGA-1070-SC-effected-by-the-VRM-overheating-issue-m2571376.aspx) this is a response ticket a user got "The hotspot issue is a misconception based on a review where the reviewer in question was running Furmark, an extreme usage case, as most overclockers know. We believe this is a good approach to have some idea about the graphics card limit, and the thermal performance under the worst case scenario. EVGA has performed a similar qualification test during the design process, at a higher ambient temperature (30C in chamber) with a thermal coupler probe directly contacting the key components and after the Toms Hardware (Germany) review, we have retested this again. The results in both tests show the temperature of PWM and memory is within the spec tolerance under the same stress test, and is working as originally designed with no issues.
As for your card, it is not affected, as the "issue" has only been found to affect the FTW models, which are a non-reference PCB. Your card, the SC, and other reference PCB models do not exhibit this "hotspot". However, if you wish to obtain the thermal pads for your card, you may do so, as long as your product is ACX 3.0 and has a backplate. To request these, please go to http://www.evga.com/thermalmod"
