Thermals and Noise
The GTX 950 FTW is a factory overclocked card with bumped up GPU frequencies, yet thanks to the ACX 2.0 cooler it is supposed to be cooler and quieter than the competitive cards. Indeed the GTX 950 FTW fans are almost inaudible in 3D and this time we can confirm there is no coil whine.
The card is silent in idle and during media playback or light gaming. Namely the card turns its fans off when GPU temperature is below 60 degrees Celsius. The screenshot below shows this works in practice. Note how fan RPM reaches zero before the fans are stopped, but this is normal since the fans can not stop rotate immediately.
You can use PrecisionX to monitor and control the fan speed.
