With the fans regulated automatically, the GPU of the Zotac card was 66☌ hot and the fans accelerated from 1400 to 2220 RPM. We didn’t replace the card’s default thermal interface. This test was performed in a closed system case at a room temperature of 20☌. We used MSI Afterburner 2.2.3 and GPU-Z 0.6.4 as our monitoring tools. Predator (2010) with the highest image quality settings at 2560×1440 with 16x anisotropic filtering and MSAA 4x antialiasing. We checked out the card’s temperature during five consecutive runs of Aliens vs. The sleeve bearing is specified to last 40,000 hours while the peak power consumption of each fan is no higher than 4.2 watts. Their speed is PWM-regulated from 1400 to 3500 RPM. Labeled FD7010H12S, the fans are manufactured by FirstD. Above them, there is a decorative metallic casing with two 70mm orange-colored fans. The pipes are soldered to the base and to the heatsink fins. They go out of the copper base and pierce the aluminum heatsink. The copper heat pipes are still 6 millimeters in diameter, though. The Zotac GeForce GTX 660 features Zotac’s original Dual Silencer in a simplified version with two rather than three heat pipes. The latest GPU-Z is already aware of the existence of the GeForce GTX 660 and reports its specs correctly.There are still no tools available that could read the BIOS of Nvidia’s GeForce GTX 6xx series cards, so let’s move on to examine the cooler. Coupled with the 192-bit bus, the GeForce GTX 660 has a peak memory bandwidth of 144.2 GB/s, like its Ti cousin. Labeled K4G20325FD-FC03, the chips have a voltage of 1.35 volts and a rated clock rate of 6000 MHz. Unlike all of the Kepler-based graphics cards we’ve tested previously (with the exception of a dual-processor GeForce GTX 690), the Zotac GeForce GTX 660 carries memory chips from Samsung rather than Hynix. In 2D mode the GPU frequency is dropped to 324 MHz at a voltage of 0.987 volts. The Zotac is pre-overclocked by a mere 13 MHz compared to the reference GTX 660. The base GPU frequency in 3D mode is 993 MHz (1059 MHz in the boost mode), which is 78 MHz higher than the base frequency of the GeForce GTX 660 Ti. It is 24.8% smaller than the GK104, but the exact transistor count is not yet disclosed. It is responsible for the memory chips and has no cooling.The card’s GK106 revision A1 processor was manufactured in Taiwan on the 31st week of 2012 (late July or early August). One phase is placed between the GPU and the video connectors. It’s surrounded by memory chips.In the back part of the PCB, below the small aluminum heatsink with thermal pad, there are four phases of the GPU voltage regulator. The GPU is placed in the center of the small PCB. A 450-watt or higher PSU is recommended for a system with this graphics card (the same as for the Ti version). The peak power consumption of the GeForce GTX 660 is specified to be 140 watts while its typical 3D consumption is 115 watts. Thus, you can only join two such cards in a SLI setup. The GeForce GTX 660 has only one MIO connector (for building SLI configurations) and one 6-pin power connector. There’s also a vent grid in the mounting bracket to exhaust the hot air out of the system case. The new card is equipped with DVI-I and DVI-D (dual-link) outputs as well as with HDMI and DisplayPort. It’s actually rather hard to tell them from each other. The Zotac GeForce GTX 660 2GB is as compact as its Ti cousin, measuring 173x100x38 millimeters. Zotac provides an extended 3-year warranty for this product. The graphics card is manufactured in China and has a recommended price of $229, exactly as the reference GeForce GTX 660 2GB. The Zotac GeForce GTX 660 2GB is shipped together with the following accessories: one power adapter, a DVI->D-Sub adapter, a CD with drivers, utilities and other software, short and long versions of the installation guide, and a coupon for downloading TrackMania 2. Key product features, supported Nvidia technologies and minimum system requirements are all listed there, too. Two icons tell you that the card’s cooler is 10☌ more efficient and 10 dB quieter than the reference one. Similar to the Zotac GeForce GTX 660 Ti, there’s a picture of the card on the back of the box. The product’s model name, memory amount, DirectX 11 support and extended warranty are all indicated on the front of the packaging: The graphics card is shipped in a small cardboard box. Like the rest of the Kepler GPUs, the new GK106 offers all modern technologies from Nvidia including adaptive V-Sync, NVENC encoder, support for up to four monitors concurrently, GPU Boost, FXAA and TXAA antialiasing.
