Guys, I have a problem with my Shappire 7970. From the start and until it hits 75ºC, the fan is completely stuck. At 0 rpm. And then suddenly, it hits 100% to lower the temperature.
As you can guess, this one of the most annoying things that I have ever heard.
The thing is, that with MSI Afterburner, if I turn the fan speed any lower than 80% manually, the fan keeps still, no change. I turn it from 79% to 80% then it suddenly revives.
Here you have an image with the problem: http://i.imgur.com/yaQvtJE.png
As you can see, the temperature and the fan "speed" keep rising, but the fan is idle, doing nothing, until it hits a certain temp and you get a spike like that one.
Any of you had ever have this problem?
