One main reason why the Zotac GTX 1070 AMP! Extreme has such a huge cooler is to provide impressive and unmatched air cooling capability. It’s big for a reason, and not just for showing off. I was able to get as low as 36° Celsius on idle, and around 39° Celsius on light load.

Even on full load, the Zotac GTX 1070 AMP! Extreme didn’t even come close to 70° Celsius; as it was just hovering around 58° to 65° Celsius even when overclocked further. That’s really an impressive and superb cooling solution; and this is one reason why you should consider the AMP Extreme variant compared to the AMP! Edition or any other GTX 1070s out there.

Zotac GTX 1070 AMP! Extreme – Noise
Aside from the superb cooling capability of the GTX 1070 AMP! Extreme’s IceStorm, the graphics card is also literally dead silent. The fans do not turn on unless they hit a certain threshold of temperature making it dead silent. Once all three fans starts to spin, the AMP! Extreme is still generally silent. I’m using an open test bench chassis and I could hear clearly whether there is noise coming from the graphics card or none. Even when I cranked up the fan speed up to 80%, the fans doesn’t sound like a jet engine. At around 80% to 100% fan speed, the fans do emit audible sound already, but they are not annoying unlike with other graphics cards.

Out of the box, the Zotac GTX 1070 AMP! Extreme already comes with factory overclock settings. It features a GPU base clock speed of 1632MHz and boost clock speed of 1835MHz, and a memory clock speed of 2502MHz. The reference GTX 1070 or the GTX 1070 Founders Edition comes with a base clock of 1506MHz, boost clock of 1683 MHz and memory clock speed of 2000MHz.

I was able to push the GTX 1070 AMP! Extreme up to 2151 MHz boost clock speed and 2227MHz memory clock speed. But it was not that easy as before where you just adjust or increase the core clock, memory clock, voltage, power limit, etc. Overclocking the new GTX 1070 graphics card is quite tricky since it now features GPU Boost 3.0, where clock speeds and voltages becomes “fluid” or variably changes.

I have written a separate guide on how you can overclock your GeForce GTX 1070 graphics card here. It’s a step by step overclocking guide that will show you how I was able to reach 2151 MHz GPU clock speeds by adjusting or editing the voltage/frequency curve. The results of (further) overclocking the GTX 1070 AMP! Extreme are reflected on the synthetic benchmark results on the next page.
