The original cooler doesn’t have a proper name as yet. Its design is simple but clever, featuring four 6mm copper heat pipes that go out of the copper base.

The pipes pierce the heatsink consisting of slim aluminum fins. Fans are attached on top of the heatsink and the whole arrangement is covered with a protective casing.

It’s hard to tell how the heat pipes contact with the copper base as we can see no trace of thermal glue or solder.

There are small heatsinks with thermal pads on the memory chips and power system components.

The fans were made by Protechnic (part number MGT9212YB-W20).

We couldn’t find their specs. According to our monitoring tools, their speed is PWM-regulated from 1300 to 3600 RPM.

Let’s see how Zotac’s original cooler copes with the fastest off-the-shelf GTX 670:

Automatic fan mode

Maximum fan speed

65°C at 1920 RPM in the automatic regulation mode and 56°C at the maximum speed of 3620 RPM – these are outstanding results for a 1098MHz GPU, even if we don’t count the boost mode in.

Unfortunately, they had squeezed everything out of the GPU back at the factory, so we could only overclock it to 1148 MHz (+50 MHz) at the default voltage. Anyway, that’s the highest clock rate among the three graphics cards in this review. The memory chips did well, too, overclocking to 7468 MHz.

When overclocked, the GPU got a mere 2°C hotter, the fans rotating at the same speed in the automatic regulation mode.

Thus, the Zotac GeForce GTX 670 AMP! Edition is something in between the top-end GeForce GTX 680, whose PCB it uses, and the GeForce GTX 670, but its excellent factory overclocking makes it faster as you’ll see in our upcoming report.
