Is this a joke?
The 5770 fan is dead/stopped and the card is throttling to keep from turning itself into a pool of bubbling plastic.
The fan isn't dead... I've ramped it up to 100% on purpose. But it is clearly running.
Have you opened the case and looked at it to make sure the blades are actually moving, that the blades haven't melted off the spindle? Your hardware monitor is showing it at 0 RPM in every picture. The speed percentage isn't a monitor it's an indicator of the speed your software is attempting to run it at.
If it is in fact actually spinning somehow I'd consider the possibility that the card's heatsink has become detached.
