We take our noise level measurements with the decibel meter on the top and middle section of the case, overhanging the side panel (power supply side, not motherboard tray side) by exactly 1 inch to avoid any airflow pressure coming from the exhausting AIO cooler.
I measured the sound floor to be 34 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.
Noise levels were measured after 5 minutes under three scenarios: desktop idle, Deus Ex: Mankind Divided at 4K, and the Fire Strike Ultra stress test.
Barely coming in louder than the MSI Gaming 8G, the noise levels of the Palit 1070 Ti are very good. It also benefits from the ‘zero dB' mode so low-load tasks like web browsing can be done in silence.
With the shortage of GDDR5X, I’m wondering if the GTX 1080 is being phased out, because this is (95% of) a GTX 1080 GDDR5. Maybe the endgame is for the 1080 to be discontinued, the GP104s going into 1070 Ti instead, and the GDDR5X to be saved for the 1080 Ti and possibly mid-range Volta cards if the early flagships use GDDR6?
