Gainward GeForce GTX 570 Phantom: Fan does not reduce speed anymore

[smoo]

Hey there!

The fan of my new Gainward GeForce GTX 570 Phantom suddenly decided to not throttle down anymore. I would guess its running at an average 65%. I tried the Gainward Tool "EXPERTool" to throttle the Fan... I can throttle it up to 100% and it works fine. If I choose dynamic the fan speed IN THE TOOL is shown decreasing 1% per second but at some point the fan of the graphic card does not reduce the speed anymore. Minimum should be 30%. What to do?

Temp is 30°C.
- Gainward GeForce GTX 570 Phantom
- Gigabyte GA-Z68XP-UD3, Z68

Any ideas?

Just unplugged the GPU from the mobo and plugged it back in: fan is reducing speed now.

Well smoo! trial and error!
That's how alot of us learn this stuff!
Glad you're working this and the other post out on your own.
My first build, i had all kinds of issues that eventually worked themselves out.

The next day: The GPU does not throttle down its speed again. :/

Talked to the support, they told me to send the GPU in.
