We've been anxious to get our mitts on EVGA's GTX 680 SC Signature 2 graphics card as this is the company's first dual fan GTX 680. The card isn’t much faster than the original GTX 680 SC Signature, i.e. 1097MHz vs. 1084MHz GPU and 1552MHz vs. 1552MHz memory, but the new cooler means a quieter card that overclocks better. Good news however is that the new card is priced the same as the original GTX 680 Signature - $519.99.
The following two photos show our temperature measurements – first up is the GTX 680 SC Signature 2, followed by GTX 680 SC Signature. The difference of 3°C says enough really, especially since the cooler was almost inaudible. The two fans don’t go over 2040RPM, while the Signature’s single fan reached 2400RPM.

Unfortunately, we’ve sent the GTX 680 SC Signature back to EVGA and we couldn’t compare the results to those of the Signature 2, since the 304.79 driver we used for the latter card give better results. Users shouldn’t expect any major differences in performance of the two Signature cards, because they’re similarly clocked. We’ll soon see whether two fan cooling helps with overclocking so stay tuned.
