So, in order to keep noise in check while cooling the GTX 780 Ti with a 104MHz factory overclock Gainward developed an exceptional cooler. Let’s see how it performs in the real world. Nvidia’s GPU Boost 2.0 watch-dog ensures that the graphics card is always running at the highest possible clock and with a massive cooler it is able to prevent significant fluctuations in operating frequencies.
The card’s maximum GPU temperature is 95 degrees Celsius but you do not have to worry with the GTX 780 Ti Phantom. Under load the GPU temperature can hit 84 degrees Celsius in some applications, but mostly we measured temperature under 82 degrees Celsius. The temperatures are similar what we got on a reference GTX 780 Ti card, but bear in mind that the Phantom ships with a 104MHz GPU overclock.
In terms of performance we have nothing to complain about. However, despite the factory overclock, the new Phantom cooler keeps the card quiet. The noise level, even under load, is acceptable for a living room setting. The fans were not loud even under load, and of course while idling the card is practically silent. In idle we measured 31 degrees Celsius.
Once the game is started and the GPU starts heating up, there are no abrupt fan speed changes.
