Temperature and Noise
With the FREEZE technology, the fans on the Zotac GTX 950 AMP! Edition turns off when under idle or light load. The fans start spinning when the GPU hits a certain temperature. I think the threshold is around 60° to 65° degrees Celsius, and that’s the time the fans start to kick in. The lowest idle temperature I got is around 36° degrees Celsius, as seen from the screenshot below. But that’s in a totally idle state. Usually the temperature plays around 40° to 50° when not in gaming.
When I fired up Fire Strike benchmark, the temperature went up to 72° degrees Celsius. It’s the highest temperature I got during my test, but it’s doesn’t constantly stays at that point. Depending on the load, the GTX 950 AMP! Edition’s temperature plays around between 53° to 70° degrees Celsius. Those are very much acceptable numbers and it shows that Zotac’s IceStorm technology is quite effective.
When it comes to noise level, the Zotac GTX 950 AMP! Edition remains dead silent during idle to light load. The fans are not running, thus no noise is being produced. However, when the fans start to spin, I noticed that it is a tad louder compared to the fans Zotac used in their GTX 970 AMP! Extreme Core edition. If you are using an open case like a test bench, or you didn’t put the side panel of your casing, you may hear some noise, specially if your casing is just right beside your monitor. But if you are using a closed casing, the noise level is barely noticeable at all.
Unfortunately, the sample we got is not coil whine-free. When the GTX 950 AMP is in full load, I can hear a certain amount of coil whine emitted by the graphics card. I thought that the coil whine would somehow disappear after several days of using it (just like in the case of our Asus STRIX GTX 970), but it didn’t go away. I’m not sure if this is just an isolated case or not, but other GTX 950 AMP! Edition graphics card doesn’t seem to have coil whine issues.
