Inno3D GeForce GTX 660 Ti HerculeZ2000S
The graphics card from Inno3D is packed into a small upright box:
There’s little information on the packaging and all of it seems to be copied from the Nvidia website. The card is shipped together with a power adapter, a DVI->D-Sub adapter, and a CD with drivers.
The card was manufactured in China. It comes with a 1-year warranty for $299.
The face side of the PCB is covered by a cooling system which is somewhat larger than the PCB itself.
The total length of the card is 203 millimeters. Its height is 42 millimeters.
The PCB follows the reference design.
So, there is nothing special about the power system.
The Inno3D boasts the newest GPU chip in this review. It was manufactured in late June or early July this year.
The base GPU clock rate in 3D mode is 915 MHz (boosted to 980 MHz), exactly like on the reference GeForce GTX 660 Ti. The memory frequency and amount are also the same as the reference card’s: 6008 MHz and 2 GB.
Thus, the Inno3D GeForce GTX 660 Ti HerculeZ2000S is the only graphics card in this review to have no factory overclocking.
That’s why the only interesting thing about this model is its exclusive cooler HerculeZ2000S. Compact and light, it consists of a dual-section aluminum heatsink with four copper heat pipes (6 millimeters in diameter), two fans in plastic frames, fan faceplates, and a metallic plate with thermal pads for the memory chips and power system components.
The heatsink fins are soldered to the heat pipes.
The two 75mm impellers are secured in plastic frames which are hooked on to the sides of the heatsink. Manufactured by Colorful, these fans run on sleeve bearings.
The speed of the fans is PWM-regulated automatically in a range of 1260 to 3240 RPM. Each fan is specified to consume no more than 3.4 watts.
Let’s see how efficient the HerculeZ2000S is:
Automatic fan mode
Maximum fan speed
The GPU was 71°C hot as the fans were automatically set at 1680 RPM. At the maximum speed of 3240 RPM the temperature was 59°C. That’s average performance compared to the other coolers in this review.
The low default clock rate helped the Inno3D do well in our overclockability test. We managed to increase its GPU frequency by 105 MHz and its memory frequency by 980 MHz.
However, the resulting GPU frequency of the Inno3D card was only 1020 MHz. This is lower than the default clock rates of the ASUS and Gigabyte cards, for example.
The peak temperature of the overclocked Inno3D was 72°C, its fans rotating at 1770 RPM.
That’s good, considering that the Inno3D is quieter than most of the other cards in this review.
