We take our noise measurements with the sound meter positioned 1 foot from the graphics card. I measured the noise floor to be 32 dBA, thus anything above this level can be attributed to the graphics cards. The power supply is passive for the entire power output range we tested all graphics cards in, while all CPU and system fans were disabled. A reading under load comes from running the 3DMark Time Spy stress test for 30 minutes.
The card's temperature results look even more impressive when we get to the acoustic testing. That's because the Phantom Gaming's three fans spun at just over 30% during our testing, typically between 1000-1100rpm, making it a fantastically quiet card, edging out even the MSI Gaming X according to our sound meter. If you value low noise, the Phantom Gaming ticks that box emphatically.
