Temperature, Noise And Power Benchmarks
The first comparison is between Zotac's cooler and the reference GeForce GTX 980. Is this third-party solution an improvement over Nvidia's popular design?
The results are surprisingly close. Zotac's cooler does take a little longer to reach peak temperature, and it beats the stock cooler's maximum by a couple degrees, but our measurements aren't anything to write home about. In fact, the reference cooler's advantage is that it pushes heated air out of the back of your case, while Zotac's cooler recirculates waste heat.
In order to focus on the graphics card's acoustics, we stop all of the system's fans during our measurement. Noise is sampled two inches from the card's output bezel.
The chart starts at 30dB, which is the practical floor of what a human might consider silence. Once again, we see near-identical performance from both solutions. That's not necessarily a bad thing because the reference cooler is quite good, but we expect more from an aftermarket solution.
Finally, let's see how power draw compares to the reference model.
We begin this chart at 80W, which is the approximate power draw of the system at idle minus the graphics card. Zotac's AMP! Omega Edition pulls almost 5W more at idle and about 4W more under a Battlefield 4 load. This certainly doesn't necessitate stepping up to two 8-pin auxiliary power connectors, so let's see what happens when we overclock the card on the next page.
