Thermal Imaging

Thermal imaging didn’t pick up anything amiss but then again we can’t see beneath the heatsink. We didn’t see any signs of thermal throttling throughout hours upon hours of testing regardless of whether it was the VRMs or core.

Acoustical Testing

What you see below are the baseline idle dB(A) results attained for a relatively quiet open-case system (specs are in the Methodology section) sans GPU along with the attained results for each individual card in idle and load scenarios. The meter we use has been calibrated and is placed at seated ear-level exactly 12” away from the GPU’s fan. For the load scenarios, Hitman Absolution is used in order to generate a constant load on the GPU(s) over the course of 15 minutes.

This card is quiet. Extremely quiet. At idle the fans turn themselves off and even when under load they’re barely audible. While the Founder’s Edition was already quiet, EVGA’s card takes near-silence to the next level.

System Power Consumption

For this test we hooked up our power supply to a UPM power meter that will log the power consumption of the whole system twice every second. In order to stress the GPU as much as possible we used 15 minutes of Unigine Valley running on a loop while letting the card sit at a stable Windows desktop for 15 minutes to determine the peak idle power consumption.

Power consumption here is pretty much in line with a cooler running yet slightly faster GTX 1080. Remember, even though it is overclocked, the EVGA GTX 1080 Superclocked ACX 3.0 allows for better thermal dissipation which leads to higher overall efficiency.
