VR Zone came across a photo of Zotac's new GeForce GTX 670 TwinCooler, a custom model that is about 60mm shorter than NVIDIA's reference design. The cooling solution features direct-touch copper heatpipes, two aluminium fin arrays and two 80mm fans. You can expect it to hit the market around June 20th.
The cooler makes the card a tiny bit thicker than what two expansion slots allow, although it shouldn't eat up the third expansion slot.
The ZOTAC GTX 670 TwinCooler, despite its compact size, packs factory-overclocked speeds. Its core (base) is clocked at 954 MHz (vs. 915 MHz reference), with a GPU Boost frequency of 1033 MHz (vs. 980 MHz reference), and surprisingly, a memory speed of 6208 MHz (vs. 6008 MHz reference, a frequency most manufacturers don't tinker with). The card packs 2 GB of GDDR5 memory across a 256-bit wide memory interface. The 28 nm GK104 silicon is configured to have 1344 CUDA cores, 112 TMUs, and 32 ROPs.
