I have been trying to set a fan curve on my gtx 660 and it doesnt want to apply it. it remain between 1200 and 1260 rpms. It wont go higher than that. It does this even on auto. It simply wont bring up the fan speed to cool down the gpu at higher temperatures. I have seen it hit 95c and i am afraid of bricking my gpu. I have used zotac firestorm, evga precision x, asus gpu tweak, and msi afterburner nothing seems to work.I have also uninstalled the drivers multiple times to no avail. I have a zotac gtx 660 synergy edition. Any help will be greatly appreciated.

Since you have tried a lot of software it's entirely possible that this perticular card does not allow custom settings. However, make sure that the graphics driver isn't set to regulate the fan speed at the same time as the other program. That could interfere.
has the card always done this since you bought it? because that could be something in the bios of the card.
