Inno3D iChill GTX 650 Ti BOOST HerculeZ 2000 2GB

The graphics card from Inno3D is shipped in a large box with a honeycomb picture on its front:

It is not the largest packaging we’ll see in this review, but the Inno3D product features a lot of accessories which are not typical of this class of graphics cards. They include a power cable, a video adapter, an Inno3D sticker, a CD with drivers, an L-shaped hex key for the cooler, and such extras as a copy of 3DMark (2013) and a high-quality mouse pad.

Manufactured in China, the card costs $190, which is a mere $20 more expensive than the other products in this review. The warranty period is 3 years.

The Inno3D iChill GTX 650 Ti BOOST looks stylish and attractive. Its face side is covered with the HerculeZ 2000 cooler whose fans are surrounded with titanium-like figured faceplates. An iChill logo can be seen between them.

The card is only 231 mm long but it is not the shortest in this review. It is the thickest, though, at 58 millimeters.

The thickness is due to the HerculeZ 2000 cooler which we will describe below. The mounting bracket with video outputs is no different from the other cards reviewed here:

The MIO connector is the same, too. The card can only be used for 2-way SLI configurations. As for additional power connectors, the Inno3D iChill GTX 650 Ti BOOST has two of them rather than only one as the other GTX 650 Ti Boost cards in this review.


The manufacturer must have tried to ensure a reserve of power for better overclocking and stability at increased frequencies. The peak power consumption written in the specs is 168 watts, which is 34 watts higher than the reference card’s. A 500-watt PSU is recommended for a computer with one Inno3D iChill GTX 650 Ti BOOST inside.

Covered with a metal heatsink, the GPU power system has four phases but is reinforced with additional solid-state capacitors.

The power system is governed by a ON Semiconductor NCP5395G controller. There are also one power phase for memory and PLL each.

The GPU is revision A1 again and is dated the 7th week of 2013. Its base clock rate is 1059 in 3D mode (boostable to 1124 MHz). It is the second fastest GPU (after the EVGA card) in this test session.


Like the Gigabyte card, this one is equipped with Hynix H5GQ2H24AFR R0C memory chips, which are pre-overclocked to 6212 MHz.

Besides its pre-overclocked frequencies, the Inno3D iChill GTX 650 Ti BOOST is interesting for its exclusive cooling system called HerculeZ 2000. It is a triple-slot cooler with an aluminum heatsink, four nickel-plated copper heat pipes (6 mm in diameter), two fans in plastic frames, and a metallic heat-spreading plate on the power components and memory chips located on the face side of the PCB.


The L-shaped hex key included into the box can be used to remove the decorative faceplates from the cooler. The fans are 90mm in diameter and their thickness is 15 mm. They are manufactured by Colorful and run on sleeve bearings:

Their speed is PWM-regulated in a range of 1000 to 2600 RPM.

We described the performance of the Gigabyte’s cooler as excellent, so now we have problems finding a suitable word for the HerculeZ 2000 because it’s even better! When its fans were regulated automatically and only reached 1230 RPM, the peak GPU temperature was only 57°C! 

Auto fan mode

Maximum fan speed

At the maximum speed of 2610 RPM, the temperature was barely above 50°C! Such a high performance is really worth the additional PCIe slot you have to give away. The triple-slot HerculeZ 2000 is just the best cooler in this review.

The Inno3D iChill GTX 650 Ti BOOST is as good as the other graphics cards in terms of overclocking potential. We could increase its GPU and memory clock rates by 70 and 600 MHz, respectively.

The resulting frequencies were 1129/1194/6812 MHz.

The HerculeZ 2000 kept the overclocked GPU as cool as 59°C without accelerating its fans much (1260 RPM).

That’s definitely the best result in today’s test session.
