You need to test these cards in games like Star Wars Battlefront, FrostBite 3 i killing them. Try it. Cos I don't think, that I need 1.26V, 1100Mhz for other games...
Overclocking is not really a thing with those cards, at least from what I see on my Fury. I tested this 1100 MHz -48mV more extensively and it crashes and needs stock voltage, and any overclock above that will crash even with full overvoltage. And for only 50MHz less at 1050 MHz I can set voltage to -90 mV and be stable. Gains from overclocking compared to power draw and temperature increase are just...pathetic.
As for FrostBite3, I think that Witcher 3 is also very merciless in terms of overclocking and stability, I always had to set my cards lower than for other games to be stable. I was testing FreeSync for like an hour running around Novigrad and some woods and swamps and it never crashed at -90mV stock or 1100 MHz stock voltage.

HWInfo reports that after 10 minutes of Valley Extreme HD, my GPU uses about 271W and 1.181V. Considering you're stock undervolt reading, I would think you'd use less wattage and voltage than my card. Does the Nitro use more power than the Tri-X?
I don't know about Tri-X, but Tri-X is reference PCB and Nitro is custom, so there may be differences. This would explain temperature and noise difference between the two in tests.
I am using HWInfo and MSI Afterburner for voltage monitoring. As for wattage, I am just measuring total power draw from the wall with wall meter or however it is called in English. And this includes monitor and speakers because I was too lazy to reconnect it, so you can cut ~25W from those measurements.

Ambient here is 22C and copying your settings (1440P, same undervolt, 35% fixed fan speed, etc.), mine hits 75C and sits there or bouncing up to 76. Same game too (Witcher 3). This is with a open side panel too.
I don't know what is causing a almost 15C different in temps we are seeing but either something is wrong with my card or you live at the North Pole.

EDIT: Yeah just changed paste, made zero different in temperatures.
Toms required around 1450RPM to maintain 75C in their review. My experience matches theirs when I close my side panel. I gotta stop believing everything on the internet.
Tests are made for ambient temperature of 23,7-24,1 degrees. I am measuring at night because during the day I have around 28C ambient temperature. Basically very hot room with 2 big windows and no ventilation, and only 2-3 degrees cooler than outside, so if there is like 36C outside than you can imagine that I am dying there
My case is Fractal Design Define R5. I am using slow RPM Silentium PC Sigma Pro 140mm fans set to 5V, which gives 400 RPM. I was afraid that they will be useless since you can barely feel any air pushed by them if you place your hand behind one, but actually they work well. There are two for front intake, one for bottom intake (1-2 degrees improvement for GPU), one for side intake (lowers temperature by another 4-5 degrees) and rear exhaust. Those measurements for fans, how much each helps, was made with R9 390, I didn't test them yet for Fury, but temp goes up quickly if I turn case fans off, so there is some airflow after all even with those not very well performing in theory fans.
Keep in mind that -90mV undervolt lowered temps from 71C to 61-62 C. On stock voltage I am getting 71.
This is how the temp scales with fan speed after undervolting (10 minutes Heaven Benchmark).:
I can make video of 10 minutes Valley run, what recording software doesn't take 500 GB for 10 minutes and won't take video on 50 parts like FRAPS?Edited by Krzych04650 - 7/28/16 at 2:48am
