FUD Zilla writes NVIDIA's GeForce GTX 970 graphics cards are selling pretty well and that stock clears out rather fast. The site also points out that some of these cards suffer from coil whine but notes that not all cards are affected, it seems that some of NVIDIA's partners decided to pick cheaper components that may produce this unpleasant noise, but with a closed case it should be hard to hear.
Some of the cards suffer from Coil Whine but at the same time, it is hard to hear this unpleasant noise in a closed case. It turns out that some components probably R22 inductors are to blame and not all the cards are affected. A lot of people wanted to RMA their cards as they didn’t like the noise.
The Geforce GTX 980 cards are not affected by the issue as all the GTX 980cards are manufactured under Nvidia supervision. One can imagine that Taiwanese partners decided to use cheaper components to make slightly larger profits as higher end components don’t get affected by the issue.
